OUR BUSINESS
Blockchain Strategic Investments
In September 2017, pursuant to a subscription agreement, we purchased an approximate 10.9% ownership in goNumerical Ltd., a leading Canadian Blockchain company known as Coinsquare Ltd., one of Canada's leading exchanges for trading digital currencies.  In connection with the foregoing transaction, we also received warrants to purchase shares of Coinsquare's Common Stock, which would result in an additional 3.8% net ownership interest, if exercised in full.

On October 20, 2017, we acquired approximately 52% of Tess Inc., a private Ontario company which is developing blockchain solutions for telecommunications companies, in consideration for our payment of $320,000 and 75,000 shares of our Common Stock.  As a result, Tess, Inc. became our majority owned subsidiary.ABOUT RIOT BLOCKCHAIN

On November 1, 2017, we acquired 100% of Kairos Global Technology, Inc. ("Kairos") in consideration for the issuance of 1,750,001 shares of our Series B Convertible Preferred Stock, which are convertible into an aggregate of 1,750,001 shares of our Common Stock, which we issued to the shareholders of Kairos. Kairos is the owner of certain new computer equipment and other assets used for the mining of cryptocurrency, specifically servers consisting of 700 AntMiner S9s and 500 AntMiner L3s, all manufactured by Bitmain.  Certain of the shareholders of Kairos also received a royalty to be paid from cash flow generated from operations, which shall entitle such shareholders to receive 40% of the gross profits generated on a monthly basis until they have received a total of $1,000,000, at which point the royalty is extinguished.

Business Strategy

The above referenced acquisitions, as well as our new name, reflect a new segment (in addition to veterinary and life science oriented businesses of the Company) being pursued by us.  The decision to invest in companies exposed to blockchain and digital currency related risks is a strategic decision by the Company.  Our strategy will be to continue to pursue opportunistic investments and controlling positions in these new and emerging technologies which will continue to expose us to the numerous risks and volatility associated with this sector.  We expect this volatility and uncertainty to continue both in terms of the acceptance or non-acceptance of blockchain transaction verification business models, as well as the value of blockchain cryptocurrency products and solutions.  The price of underlying digital currencies (referred to herein as "cryptocurrencies") have varied wildly in recent periods and may reflect "bubble" type volatility in the future, meaning that support for high prices may have little or no merit, may be subject to rapidly changing investor sentiment, and may be influenced by unknown factors such as technology challenges, regulatory uncertainty, fraudulent actors and media reporting.  We anticipate we will continue to increase our exposure to this industry through passive investment, majority owned or controlled investments, and organic expansion, but do not presently intend to invest in any manner that would result in us being required to register as an investment company, although the SEC, NASDAQ and other government or quasi-governmental agencies or authorities (in the United States or elsewhere) may adopt further regulations that require such registration or expose us to similar registration requirements that could increase costs, make such activities undesirable, or prohibited, and further regulate, impede, impose costs or outright prohibit some of the activities we are or may become involved with.  These factors are incapable of prediction and are out of our control.  Depending, in part, on the evolving nature of rules and regulations governing blockchain and cryptocurrency, our investments and these businesses may become worthless and the value of an investment in our securities could be volatile and potentially worthless.

Description of Coinsquare's Business

Coinsquare is a Canadian digital currency platform, enabling the buying and selling of various digital currencies, including Bitcoin, Bitcoin Cash, Ether, and Litecoin. Coinsquare's view is that each country requires a digital currency platform that is bound by existing and forthcoming regulation of each geographic location, and so has focused on building its platform, support and marketing expertise specifically in Canada. Their revenue model consists of charging fees on customer deposits, withdrawals, and transaction volume.  Coinsquare's mission is to provide an easy-to-use, cost-efficient, and trustworthy way to buy and sell digital assets.

Description of Tess, Inc.'s Business

Tess is in the early stages of developing its TESSPAY transaction settlement service.  The TESSPAY transaction settlement service aims to be first applied, by way of proof of concept, to the global telecommunications industry to settle cross border voice call minutes transferred between telecommunications carriers. The intention is for transactions between telecos to be effected under TESSPAY Smart Contracts using fixed value closed loop TESSPAY-Minute-Tokens. Miners who may operate and secure the blockchain semi-public ledgers in support of these transactions will be rewarded by receipt of TESSPAY-Minute-Tokens dispensed by TESSPAY for work done.

Following a potential entry into the global telecommunications industry, TESSPAY intends to proceed to develop blockchain based settlement solutions for component and sub-component cross border supply chains such as those embedded in commercial aircraft fabrication, automobile production, electronic device assembly, and the retail supply chain.
Description of Kairos Global Technology, Inc.'s Business
Kairos is in the early stages of developing and deploying technological assets for cryptocurrency mining.  Kairos is the owner of certain computer equipment and other assets used for the mining of cryptocurrency, specifically servers consisting of 700 AntMiner S9s and 500 AntMiner L3's, and manufactured by Bitmain.

Historical Operations
We hold an exclusive license agreement with Washington University ("WU") in St. Louis which granted us an exclusive license and right to sublicense its technology for veterinary products worldwide, subject to certain exceptions.  In July 2012, we granted Ceva Sante Animale S.A. ("Ceva") an exclusive royalty-bearing license to our intellectual property and other assets, relating to recombinant single chain reproductive hormone technology for use in non-human mammals.  This license includes a sublicense of the technology licensed to us by WU.  Ceva continues to advance development of the bovine rFSH product and cumulative cash payments received to date by us from Ceva have been approximately $2 million.
On February 25, 2016, we completed the sale of our corporate headquarters, land and building, to a third party at a purchase price of $4,053,000.  The sale generated approximately $1.8 million in net cash after expenses and mortgage payoffs. In addition to agreeing to the sale, we rented back space in the building under short-term lease agreements that provide storage space required for our current level of operations.
Through our wholly owned subsidiary, BiOptix Diagnostics, Inc. ("BDI"), which we acquired in September 2016, we have developed a proprietary Enhanced Surface Plasmon Resonance technology platform for the detection of molecular interactions.  We acquired a Surface Plasma Resonance (SPR) platform which seeks to combine high sensitivity with microarray detection capability to allow researchers to understand whether their target molecules have functionality against the disease targeted. SPR is an advanced and highly sensitive optical technology that can measure refractive index changes on a sensor chip's gold surface due to a change in mass that occurs during a binding event. This change can be used to monitor biological interactions such as the concentration of target molecules, kinetic rates and affinity constants.
BDI is a life science tools company that provides an affordable solution for drug discovery scientists who require label-free, real-time detection of bio-molecular interactions.  BDI manufactures, sells and services instruments and consumables to pharmaceutical researchers allowing them to develop new drugs faster than by using older technologies such as enzyme-linked immunosorbent assay or "ELISA". BDI was originally established with technology developed in conjunction with Dr. John L. "Jan" Hall, Adjoint Professor, JILA (University of Colorado), who shared the Nobel Prize for Physics in 2005 for his work on laser-based precision spectroscopy and the optical frequency comb technique. SPR is the core of the BDI products and intellectual property.  Dr. Hall, in conjunction with the scientists at BDI, created a common path interferometer that was commercialized to become the 404pi instrument.

When it was acquired by us in September 2016, BDI was in the initial stages of rolling out its first commercial product, the 404pi system.  BDI's initial revenue was generated in 2014 with first sales to customers including sales to leading academic researchers and biotech companies. BDI did not experience any significant seasonality to its business and provided normal terms to its customers, generally 30-60 days, net. Currently there is no back-log of orders.
Following the September 2016 acquisition of BDI, we began hiring sales, marketing and operational employees, adding a total of eight employees to the twelve hired in connection with the acquisition.Company Background
 
The BDI products include a reader instrument (404pi) and the consumable test products consisting of test chips (cassettes) and packaging.  The instrument is assembled in-house using primarily off the shelf parts and certain customized components.  Consumable test product components are manufactured at the BDI facility using certain sub-assemblies processed by third-party contractors. Raw materials and certain sub-components are acquired from a number of suppliers. 
Effective January 14, 2017, the Company adopted a plan to exit the business of BDI and commenced a significant reduction in the workforce. The decision to adopt this plan was made following an evaluation by the Company's Board of Directors in January 2017, of the estimated results of operations projected during the near to mid-term period for BDI, including consideration of product development required and updated sales forecasts, and estimated additional cash resources required. Accordingly, the historical results of BDI have been classified as discontinued operations for all periods presented.  During the fourth quarter of 2017, all then remaining assets of BDI which at that point were not material, had been disposed of.
Following the decision to exit the BDI business, we have begun making investments in entities in the digital currency and blockchain sectors, while continuing to evaluate other potential strategic alternatives. We expect, in the near term, to establish further consider alternatives as we evaluate our next steps and strategic path forward with the goal of maximizing value for our stockholders.

We were incorporated on July 24, 2000 in the stateState of Colorado under the name "AspenBio,AspenBio, Inc.", which was subsequently changed to AspenBio Pharma, Inc. In December 2012, we changed our name to "Venaxis,Venaxis, Inc." and in 2016, in connection with our acquisition of BiOptix Diagnostics, Inc., we changed our name to "Bioptix,Bioptix, Inc." and as of October 19, 2017 we changed our name to Riot Blockchain, Inc., to reflect our new focus on our blockchain business. That operational focus and the Company's recently completed acquisitions of Kairos Global Technologies, Inc. ("Kairos") and 1172767 B.C. Ltd., formerly known as Tess Inc., and its investment in goNumerical Ltd., (d/b/a "Coinsquare"), as well as the Company's new name, reflects a strategic decision by the Company to operate in the blockchain and digital currency related business sector. On March 26, 2018, the Company also acquired 92.5% of Logical Brokerage Corp. ("Logical Brokerage"). Logical Brokerage is a futures introducing broker headquartered in Miami, Florida registered with the Commodity Futures Trading Commission, and a member of the National Futures Association.

In September 2017, we changed our state of incorporation to Nevada from Colorado. Our principal executive offices are located at 202 6th Street, Suite 401, Castle Rock, CO 80104 and our telephone number is (303) 794-2000. Our website address is www.riotblockchain.com.www.riotblockchain.com. The information contained on, or accessible through, our website is not part of this prospectus.

Management Changes
The Company experienced significant changes to its management and board of directors in 2018 and 2019, including: (i) the resignation of its chief executive officer and chairman of the board of directors, John O’Rourke on September 8, 2018, (ii) the subsequent appointment of Christopher Ensey as the Company’s Interim Chief Executive Officer, (iii) the appointment of Remo Mancini as chairman of the board of directors, who had previously served as a member of the board of directors beginning on his appointment in February 2018; (iv) the resignation of Mr. Andrew Kaplan from his position as an independent member of the board of directors as of October 22, 2018; (v) the subsequent appointment of Mr. Benjamin Yi to serve as an independent member of the board of directors as of October 23, 2018; (vi) the termination of Mr. Ensey as Interim Chief Executive Officer effective February 5, 2019; and (vii) the appointment of Mr. Jeffrey G. McGonegal as Chief Executive Officer of the Company effective February 6, 2019.
These changes to the management and the board of directors of the Company during 2018/19 have been made according to the needs and strategic vision of the Company.  Management and the board of directors believe these changes will enable the Company to achieve its short- and long-term goals of (1) improving the operational effectiveness of its mining operations, (2) developing its RiotX exchange, (3) raising additional capital, and (4) improving the efficiency and cost-effectiveness of its operations and management over the medium and long terms.

Digital Currency Mining Operations

Overview of Mining Operations

The primary focus of the Company is our digital currency mining operations.  Digital currencies are digital or virtual currencies used as a medium of exchange outside of the traditional state-backed fiat currencies. Digital or "crypto" currencies rely on complex cryptographically recorded data entries known as "blocks" on decentralized digital ledger system known as a blockchain.  Blocks are added to the blockchain chronologically and, once added, are unchangeable. Thus, digital currencies are seen as a secure means of storing and recording information regarding a transaction or set of transactions.  To incentivize the creation of blocks for the blockchain, digital currency tokens are awarded on a per block basis for block creation, a process which is known in the industry as mining.

The Company's mining operations focus primarily on bitcoin mining.  Bitcoin mining entails solving complex mathematical problems using custom designed and programmed application-specific integrated circuit computers (referred to as "miners"). Bitcoin miners provide transaction verification services to a given blockchain by solving complex algorithms to encode additional blocks into the blockchain, which blocks serve as immutable records of transactions once added to the blockchain. When a miner is successful in adding a block to the blockchain, it is rewarded with a fixed number of bitcoin. Blocks are added to the blockchain on a first-to-finish basis, meaning that the first miner to solve an algorithm and verify a given transaction is the only miner to receive a bitcoin reward.  This first-to-finish environment has created a computing power arms race whereby miners are encouraged through competition to allocate ever-increasing computing power (known as "hash rate") to solving algorithms.  The resulting energy costs are substantial, and, in light of the recent decline in the market price of bitcoin and other "benchmark" digital currencies such as bitcoin cash, litecoin, and ethereum, the profitability of mining operations has been reduced as competition increases to solve each block.  The Company's digital currency mining operations operate at a maximum hash rate of 95 petahash per second.

In response to these factors, the Company has entered into mining pools, whereby multiple miners allocate their collective computing powers to solving a given algorithm thereby increasing the collective hash rate devoted to a given algorithm. By pooling their efforts, miners in a pool are more likely to verify a given transaction and add a block to the Blockchain than miners acting individually.  Pool miners are awarded a fractional reward based on the hash rate each contributed to the pool on a given successful transaction, regardless of whether the individual miner actually solved the applicable algorithm.  Miners are allocated a share of every reward obtained by the pool operator, and thus the risk of not solving the algorithm first is reduced.  The Company participates in pools on an at-will basis, and is under no obligation to remain in a given pool and may terminate its engagement with a given pool at any time.  Presently, management believes participating in mining pools is the most efficient means of mining digital currencies, but is under no obligation, nor does it provide any assurance that it will continue to do so in the future.  

Oklahoma City Mining Facility

Beginning in February of 2018, we relocated our mining operations to our Oklahoma City facility, which is leased by our subsidiary, Kairos. As of the date of this prospectus, we moved all of our 8,000 digital currency “miners,” which includes 7,500 model S9 and 500 model L3+ miners to our Oklahoma City facility.  These miners have been installed and operational since being deployed in June of 2018. Kairos leased the Oklahoma City facility from 7725 Reno #1, L.L.C.  (“7725 Reno”) by a lease agreement dated February 27, 2018, as amended on March 26, 2018 (the “Lease”). Effective as of November 29, 2018, Kairos amended the Lease with 7725 Reno by: (i) extending the initial term of the Lease through August 15, 2019; (ii) effective as of December 1, 2018, changing the monthly rent for the Lease as follows: (a) $235,000 for December of 2018, (b) $230,000 for January of 2019, and (c) $190,000 per month thereafter for the duration of the Lease, including any renewals; (iii) reducing the monthly electricity usage charges due under the Lease; (iv) providing that Kairos will reimburse 7725 Reno for up to $14,000 of the costs of installing electricity metering devices in the facility; and (v) Kairos will have the option to renew the Lease for up to two (2) three (3) month periods after the expiration of the initial term of the Lease. Under the initial terms of the Lease, the Company was required to pay for 12 megawatts of power per month, regardless of the actual power consumption by its miners.  Before upgrades were made to the software of our miners which made our mining activities much more energy efficient, this fixed cost arrangement was beneficial to the Company, as the Company had access to the allotted 12 megawatts of power each month during a time of peak demand for electric power.  When the original lease was entered into, computing power, and therefore electricity, was in high demand among competitors in the bitcoin mining marketplace; securing access to 12 megawatts of electric power per month at a fixed price was important given those market conditions. Subsequent changes to the software of our miners and facility improvements have made the miners far more energy-efficient and therefore this fixed cost arrangement had become cost-inefficient, as the Company used less than the allotted 12 megawatts of power per month. Accordingly, for these reasons and other economic factors, the Company renegotiated the Lease.

The changes to the Lease will not impact the number of miners deployed at the facility.  The Company's monthly electricity usage costs are now variable, rather than fixed under the Lease, and are assessed at a lower rate per kilowatt/hour for the electricity used.  The reduction in the base rent was the product of negotiations between the Company and 7725 Reno and reflects changes to the economics of the Lease, rather than any change in the leased space or the number of deployed miners.  These changes to the Lease will allow the Company to be more responsive to changes in the profitability of its digital currency mining operations.

The Company can, under the amended Lease, decide to reduce or temporarily switch off, any number of its miners in the facility and therefore reduce its variable electricity costs for that period. Whereas under the original Lease, the Company would have still incurred the same electricity cost, regardless of actual electricity use. These changes allow the Company to monitor its monthly costs by optimizing its mining performance by operating its miners at less than full capacity during times of peak electricity rates.

Miners generate a substantial amount of heat when operating, which heat must be dissipated to avoid damaging the miners’ circuitry.  Heat dissipation requires significant electrical power. As the hash rate produced from operation of the miners is increased, so too is the electricity used both in operation and from heat dissipation. Accordingly, the electricity cost incurred in operation of the miners increases exponentially as the hash rate produced is increased. This increased electricity usage comes at substantial cost to the Company, and, accordingly, when the conversion spot price of bitcoin declines, the profitability of operating the mine at peak capacity declines.  In addition to the need to dissipate the heat generated from the operation of the miners, environmental heat must also be dissipated. Under the original Lease, the Company incurred the same electricity cost regardless of electricity used, so it was negatively incentivized to reduce or halt its mining activities in response to dips in the conversion spot price of bitcoin. Under the amended Lease, however, the Company can reduce or even halt the operation of its miners temporarily in response to changing market conditions and obtain a corresponding reduction of its electricity costs for its facility. Furthermore, the Company expends electricity in dissipating environmental heat affecting its miners. As the environmental heat increases, so does the amount of electricity required to dissipate that heat. In times of extreme heat, the cost of dissipating the heat from operation of the miners can be substantial. Accordingly, running the Company’s miners at peak capacity during times of high heat is more expensive for the Company.  Because the amended lease does not have a fixed power cost built in, the Company can reduce, increase, or even shut off the mining power devoted to the miners when environmental factors or market forces contract the net revenue generated from the Company’s mining activities, without incurring the high fixed power cost required under the original lease.  This variability in the Company’s power costs resulting from the operation of its mining facility makes the Company’s mining activities more responsive to variables affecting the cost of digital currency mining, therefore bringing more of the Company’s variable expenses under the Lease within management’s control.  
Development of a U.S.-based Digital Currency Exchange

Overview of the RiotX Exchange

In addition to those business developments previously reported by the Company in its annual report on Form 10-K, quarterly reports on Form 10-Q, and periodic reports on Form 8-K, the Company has continued its exploration of the development of a U.S.-based digital currency exchange.  The Company has been investigating and pursuing the regulatory pathway for the launch of a digital currency exchange in the United States since the beginning of 2018. The Company’s planned digital currency exchange under the name “RiotX” is being developed by and is contemplated to be operated through the Company’s subsidiary, RiotX Holdings, Inc. (“RiotX Holdings”). The Company believes that, by providing a stable and secure platform for the exchange of digital currencies, it will attract significant trading volume, thereby providing the Company with consistent revenue per trade, independent of the price of any one digital currency. The Company intends to launch RiotX for the exchange of bitcoin, bitcoin cash, litecoin, and ethereum (the “Exchanged Currencies”) and for U.S. Dollars. The Company has selected the Exchanged Currencies for exchange on RiotX based on internal and external reviews, and will only include those currencies for which it has obtained regulatory approval.
The Company views its RiotX exchange as being comprised of three core services: (i) Banking Services; (ii) a Trading Engine; and (iii) Digital Wallet Services. The Company intends to provide each of these services by engaging experienced third party vendors in the industry through software-as-a-service agreements, which will be reviewed on a case-by-case basis by the Company's management, along with external advisors and legal counsel, and will ultimately be subject to review by the Company's board of directors.  The Company plans to only contract with companies that have established track records as industry leaders, which comply with federal, state and local laws, and, if required are in compliance with U.S. securities law to provide such services.  The Company assesses each vendor using a risk management process that evaluates key risk factors related to their performance and their potential impact on the Company, including, without limitation, its capital structure, financial condition and liquidity.  The Company has engaged external advisors and legal counsel to review contracts and conduct due diligence related to financial stability and performance, and cybersecurity procedures.  Additionally, the Company assesses each vendor as they relate to its regulatory compliance framework needs such as reporting, fraud monitoring, "know your customer," anti-money laundering, and data privacy standards to ensure compliance with applicable rules, regulations, and industry best practices.

Agreements with Third Party Vendors

As the Company continues to explore and develop its planned U.S.-based digital currency exchange, it will continue to develop relationships with third party vendors to support the RiotX exchange. As of the date of this prospectus, the Company has entered into several such relationships with third parties to provide RiotX with these core services. 

(i) Banking Services

As previously reported in the Company's Current Report on Form 8-K filed on October 29, 2018, the Company's subsidiary, Logical Brokerage, entered into a material definitive agreement with Synapse Financial Technologies, Inc. ("SynapseFi"), and its partner, Evolve Bancorp, Inc., through its subsidiary, Evolve Bank & Trust (collectively, "Evolve"), to provide RiotX with banking services and transactional support (the "SynapseFi Agreement"). SynapseFi's proprietary software technologies will provide the RiotX exchange with secure banking services to enable RiotX users to efficiently and securely create accounts to hold, transfer, and deliver Exchanged Currencies, allowing RiotX users to make deposits and take withdrawals of fiat currencies into and from their RiotX user accounts.  SynapseFi is an industry leader in the provision of Application Program Interfaces ("API") to the financial services industry. SynapseFi's APIs provide a secure and stable means of communication between users and financial institutions, while providing security and compliance assurances to financial institutions. Under the terms of the SynapseFi Agreement, SynapseFi will engage Evolve, or any prospectus supplement.successor financial institution designated by SynapseFi, to provide banking services directly to RiotX and its end users. SynapseFi's API will allow RiotX to efficiently communicate user requests to Evolve, while assisting Evolve with managing the risks and compliance concerns associated with the exchange of digital currencies. Pursuant to the terms of the SynapseFi Agreement, the Company has agreed to permit SynapseFi to conduct periodic security, compliance and risk reviews, and audits of RiotX on behalf of Evolve as a means of ensuring continued compliance. The SynapseFi Agreement is a significant milestone in the development of the planned RiotX exchange.

(ii) Trading Engine

On August 31st, 2018, the Company signed a Software Licensing and Subscription Services Agreement (the "Coinsquare Agreement") with Coinsquare to provide the Company with a comprehensive digital currency exchange platform inclusive of a Trading Engine and Digital Wallet Services. Under the Coinsquare Agreement, Coinsquare would have been responsible for the day to day management, hosting, customer support and other operational services. In total, the Coinsquare Agreement constituted an initial cost for the first year in excess of $1,500,000 and an equity grant of 9.9% of the equity interest in RiotX Holdings, as well as an additional 450,000 shares of the Company's common stock. The Coinsquare Agreement was terminated by mutual agreement of the Company and Coinsquare on September 17, 2018, as reported by the Company in its Current Report on Form 8-K filed on September 18, 2018.  Termination of the Coinsquare Agreement caused the Company to search for replacement third party service vendors to fulfil the roles which would have been performed by Coinsquare under the Coinsquare Agreement.

As reported in the Company's press release disclosed in its Current Report on Form 8-K filed on November 28, 2018, RiotX Holdings, Inc. entered into a Master Services Agreement with Shift Markets, Ltd. ("Shift") to provide the Company with a license to use Shift's exchange trading platform on RiotX. After conducting a search and review of third party service vendors to provide RiotX with a Trading Engine, the Company selected Shift for RiotX. The agreement between RiotX Holdings and Shift (the "Shift Agreement") provides the RiotX exchange with a license to use Shift's proprietary Trading Engine, which allows for the efficient and effective exchange of the Exchanged Currencies for U.S. Dollars.

Shift will only replace the Trading Engine component of the services which were to be provided to RiotX by Coinsquare under the Coinsquare Agreement. As a result, the Company plans to take on the role of customer support, account management and operations internally and is seeking out a third party Digital Wallet Services provider. In order to accommodate this change, the Company has revised its operating budget for RiotX to include a reallocation of the costs for headcount and other internal investments that were previously supported by Coinsquare.

The Shift Agreement is for an initial term of 12 months, which may be renewed for a period of six months by the Company.  The Shift Agreement is payable in two separate amounts: an initial set up charge, and recurring monthly fees.  The recurring monthly charges will not accrue and become payable prior to (i) integration of Shift's trading engine into the RiotX exchange is completed, and (ii) the RiotX exchange becomes operational and is launched by the Company. The Shift Agreement may be terminated at will by the Company, upon delivery of 60 days' notice to Shift.  Termination of the Shift Agreement will terminate all performance obligations of Shift and the Company.

The selection and integration of a Trading Engine into the planned digital currency exchange represents a milestone in the development of RiotX. While Shift Markets will provide a necessary tool to the Company's planned digital currency exchange, the Shift Agreement itself is financially immaterial to the Company, representing less than 5% of the Company's operating budget for its planned RiotX exchange, its contract price is less than 10% of the contract price of the Coinsquare Agreement, and it does not include an equity grant.  Shift, while an effective service provider, is not so unique to the market for exchange platform technologies to be material to the Company's strategic vision or success. Management believes the Shift Agreement will ultimately prove beneficial to the Company and its planned digital currency exchange, and that it represents an important milestone in the development timeline of its planned digital currency exchange.

(iii) Digital Wallet Services

The Company plans to integrate a third party service vendor's Digital Wallet Services technology into the RiotX exchange which, along with Shift's Trading Engine and SynapseFi's Banking Services, will complete the development of RiotX. Digital Wallet Services will provide RiotX exchange users with secured digital means of storing digital currencies for exchange on RiotX.  Digital Wallet Services are a core component of the Company's planned RiotX exchange, and will be integrated into RiotX by Shift as soon as a service vendor is selected and an agreement is finalized. Once the Company has consummated an agreement with an appropriate Digital Wallet Services provider, the Company will be in a position to start bringing its RiotX digital currency exchange online in those jurisdictions where it has obtained regulatory approval.

Project Timeline for RiotX

The Company anticipates launching its RiotX digital currency exchange by the end of the first half of 2019, which plan is subject to change based on several factors as discussed in this Prospectus. Once RiotX is online, the Company plans to offer services in a limited number of states in order to validate the performance of the system and debug any potential issues with the software. Throughout this time, the Company plans to increase staff levels to support additional users and refine its procedures for compliance, security and general support of RiotX. As the Company obtains the necessary regulatory approval in a given jurisdiction, the Company intends to bring RiotX online in that jurisdiction, with the ultimate goal of bringing RiotX online in all 50 states except Hawaii and Wyoming by the end of 2019. The regulatory hurdles faced by the Company, and its progress in this regard, is discussed in greater detail under the section titled "Regulatory Framework of RiotXbelow.  Management believes this timeline is achievable, but, in light of difficulties in obtaining regulatory approval, reaching software-as-a-service agreements with third party vendors, and capital restrictions affecting the Company, this timeline may be delayed.

Reaching software-as-a-service agreements with third party vendors for the RiotX exchange has delayed the Company's development of the RiotX exchange. Termination of the Coinsquare Agreement required the Company to replace Coinsquare with other providers that would fulfill various technology components (such as the Trade Matching Engine and Digital Wallet Service for RiotX), as well as customer support and management services, all of which were to be handled by Coinsquare staff under the original Coinsquare Agreement. In addition to allocating its own personnel and resources to handling the customer service and troubleshooting aspects of the RiotX exchange, which would have been handled by Coinsquare under the Coinsquare Agreement, the Company must integrate the services of third party vendors into the RiotX exchange to provide the Company with the necessary services for the development and operation of RiotX.
6

The Coinsquare Agreement would have fulfilled many of the outstanding development milestones for the planned RiotX exchange, but after termination of the Coinsquare Agreement, the Company entered into the SynapseFi Agreement to provide RiotX with the necessary banking services.  Additionally, the Company entered into the Shift Agreement to provide RiotX with a license to use Shift's exchange Trading Engine platform.  Finally, the Company is working towards contracting with a third party vendor to provide RiotX with Digital Wallet Services. With the Shift and SynapseFi agreements in place, once the Company has secured a digital wallet service provider, it will be in a position to deploy the RiotX exchange in all jurisdictions in which it has obtained regulatory approval.

The timeline to launch the RiotX exchange will depend on several factors including, but not limited to: performance of the Company and its ability to finance its deployment; the federal and state regulatory landscape; the ability of the Company to secure proper licensing in each state in which it intends to operate; the Company's technology implementation schedule; and the Company's ability to raise capital to continue funding the development of the RiotX exchange. Any delay in these factors, as well as additional unforeseen or unforeseeable factors, may result in the delay of the launch of the RiotX exchange platform.

Cost of Development and Operation of RiotX

Prior to the anticipated launch by the end of the first quarter of 2019, the Company estimates the initial development costs of launching the RiotX exchange inclusive of software development, license applications, legal fees, and general overhead should not exceed $250,000.  This estimate is based on current projections, and is subject to change as factors such as protracted legal costs affect the cost profile of the development of the RiotX exchange. Once operational, the RiotX exchange budget for 2019, inclusive of the contract costs of the Shift and SynapseFi agreements, as well as the to-be-determined Digital Wallet Services provider agreement, employee, utility, regulatory, and legal costs, is not anticipated to exceed $2,000,000 per year.  Factors such as rapid growth, changes in the regulatory landscape, and changes in our business plan could have a material effect on these estimates, and, as such, these costs are subject to change over time. You should not assume that the estimates disclosed under this subheading of this prospectus are accurate on any date subsequent to the date set forth on the front of this prospectus. Additionally, the Company will continually provide updated disclosures reflecting any and all material changes to our affairs that have occurred since the end of the latest fiscal year that we file with the Securities and Exchange Commission under the terms of Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, including, if not included in a report on Forms 10-K, 10-Q, or 8-K incorporated by reference therein, by providing updated disclosures in any applicable prospectus, prospectus supplement, or free writing prospectus.

Regulatory Framework of RiotX

As of the date of this prospectus, RiotX is licensed and/or approved in five states and has pending licenses in another 17 states, with review in another two states. The Company plans to be operational in 24 states by the launch date of RiotX by the end of the first quarter of 2019.  However, management continues to work towards the long-term goal of obtaining regulatory approval of the RiotX exchange in all 50 U.S. states, with the exception of Hawaii and Wyoming, by the end of 2019, which timeline is subject to delays caused by regulatory review, market forces, and other factors which may be outside of the Company's control.

In furtherance of its plan to obtain regulatory compliance, the Company purchased 92.5% of Logical Brokerage, which is an introducing broker registered with the Commodities Futures Trading Commission and the National Futures Administration, in March of 2018. The Company subsequently obtained a Money Services Business License from FinCEN in May of 2018. The Company then obtained a Money Transmitter License from the State of Florida in June 2018. In October of 2018, Logical Brokerage and RiotX were approved for application in a consortium of 17 states for fast track approval for Money Transmitter Licenses. We expect to receive these licenses in the first quarter of 2019. In December of 2018, RiotX obtained a Sellers-Issuers of Payment Instruments and Money Transmitter License from the State of Georgia. By the end of the first quarter of 2019, the Company plans for RiotX to be approved in 24 states in the United States. These additional licenses may permit the Company to explore additional exchange developments in the future.

Throughout 2019, the Company plans to pursue additional money transmitter licenses in the United States for RiotX, as well as a New York State Bitlicense, which will license the RiotX exchange to engage in cryptocurrency business in New York.  The New York State Bitlicense is seen as a benchmark license in the cryptocurrency business, and has traditionally been difficult to obtain.  In the third and fourth quarter of 2018, however, New York State regulators have increased the number of New York State Bitlicenses issued, and have done so at a greater frequency than in previous quarters.  While management does not believe this bears any indication on its own application, management believes this movement indicates increasing action by New York State regulators to grant state licenses. The Company may not, however, ever succeed in obtaining a New York State Bitlicense for RiotX, and RiotX may therefore never obtain regulatory approval to conduct cryptocurrency business in New York.  This lack of regulatory approval in one of the largest and most economically important states in the United States could have a detrimental effect on the planned RiotX exchange, which may have a material negative impact on our business operations.

Business Risks Associated with RiotX

The Company has devoted significant resources to the development of the planned RiotX exchange and the Company may lose most or all of its investment if RiotX fails. If the Company faces significant delays in the deployment of RiotX, or if the development costs of RiotX become unbearable, the Company may have to reduce or even halt its efforts to develop and deploy RiotX. If the Company is unsuccessful in the deployment of RiotX, it may lose most or all of the capital it has invested into the exchange. Additionally, if RiotX is not adopted by users, it may never gain traction in the market and become viable long-term. These risks to the deployment and adoption of RiotX pose significant risks to the capital the Company has invested in RiotX and the Company may be unable to sustain the short- and long-term costs associated with the development of RiotX.
Liquidity and Capital Resources
The Company has experienced recurring losses and negative cash flows from operations.  We expect to continue to incur losses from operations for the near-term and these losses could be significant as we incur costs and expenses associated with recent and potential future acquisitions and development of the RiotX exchange platform, as well as public company, legal and administrative-related expenses being incurred. We are closely monitoring our cash balances, cash needs and expense levels.

As of September 30, 2018, the Company had approximate balances of cash and cash equivalents of $1,607,000, a working capital deficit of $1,178,000, total stockholders' equity of $16,532,000 and an accumulated deficit of $185,796,000. To date, the Company has in large part relied on debt and equity financing to fund its operations.  As of the date of this prospectus, the Company has been closely monitoring its cash and cash equivalents and has reduced its operating expenses, as needed, in order to continue to execute the Company's strategy.  Management believes that the Company will require additional capital to meet its obligations arising from normal business operations for the next twelve months.  Without additional capital, the Company's ability to continue to operate as a going concern will be limited. If unable to obtain adequate capital, the Company could be forced to reduce or cease its operations. The Company is currently pursuing capital transactions in the form of debt and equity; however, management cannot provide any assurance that we will be successful in its plans.

Cash flow from our operations relies substantially on our ability to continue to mine digital currencies and the conversion spot price at which our digital currencies are exchangeable for U.S. Dollars.  We expect to generate ongoing revenues from the production of digital currencies, primarily bitcoins, in our Oklahoma City mining facility. Our ability to liquidate bitcoins at future values above the cost of production of bitcoins will affect our ability to generate positive cash flow from operations. However, our primary variable expense associated with our mining operation is the electricity expense of operating our Oklahoma City facility. Accordingly, the revenue from our mining operation is a function of the conversion spot price of bitcoin to U.S. Dollars over our electricity and other variable costs associated with operating our mining facility.

As of the date of the prospectus, the trading spot price of bitcoin, our primary digital currency asset, has significantly declined from its highest conversion spot price in 2018. Management has determined that a conversion spot price for bitcoin of $3,000 per bitcoin is the lowest acceptable "floor price" at which continued peak operation of the mine comports with the Company's short- and long-term strategies. At a conversion spot price at or below $3,000 per bitcoin, the ratio of revenue generated to operating costs from our digital currency mining operation is not supportable based on current internal projections. Should the spot price of bitcoin fall below $3,000 per bitcoin, management may reduce or completely deactivate its digital currency miners as a cost-saving measure.  Management could substantially reduce or cease the Company's mining activities until such a time as bitcoin begins to trade at a more advantageous conversion spot price against the U.S. Dollar, at which point the Company could immediately re-initiate its miners and resume bitcoin production from its mining facility. 
8

If the spot price of bitcoin were to consistently trade at or below $3,000 per bitcoin and management were to successfully reduce or eliminate its variable operating expenses associated with its digital currency mining operation, sell certain of its salable assets at prices below fair market value, reduce payroll and delay the launch of its RiotX exchange, management believes that the Company can continue as a going concern for at least three months.  This estimate is based on current internal projections of the Company's expenses, and does not account for unforeseen or unforeseeable costs such as additional legal or regulatory expenses which the Company cannot reasonably predict.  Should such isolated or continuing unpredictable costs occur, the Company's predictions could change materially.

The Company does not, at present, anticipate initiating these cost mitigation efforts, but is prepared to do so should access to capital markets not materialize in the short-term. Cutting its core mining operations, reducing its payroll, and delaying the development and launch of its RiotX exchange platform may have a material negative impact on the trading price of our common stock, and our shareholders may lose part or all of their investment.  Management believes, however, that continued decline in the conversion price of bitcoin to U.S. Dollars may reduce cash flow to the extent that the Company is forced to engage in these cost-saving measures in order to continue as a going concern.
On January 28, 2019, as reported on our current report on Form 8-K filed on February 02, 2019, the Company secured $3,000,000 of proceeds in connection with the issuance of senior secured promissory notes and warrants.  As previously disclosed, the debt incurred in this financing transaction permit the conversion of the principal balance of the notes into shares of our common stock as well as the future cashless exercise of an equal number of warrants for the purchase of shares of our common stock at the initial exercise price of $1.94 per share.

Additionally, even if the present trend of the decline in the conversion price of bitcoin to U.S. Dollars reverses and the Company is able to convert its digital currency assets to U.S. Dollars at a more advantageous price, the Company will need to raise additional capital to continue its operations and pursue its strategies, including the development of RiotX, and the need to respond to competitive pressures or unanticipated working capital requirements. The Company may not be able to obtain additional debt or equity financing on favorable terms, if at all, which could impair our growth and adversely affect our existing operations. 
If the Company raises additional equity financing, the Company's shareholders may experience significant dilution of their ownership interests, and the value per share of the Company's common stock could decline. Furthermore, if the Company engages in additional debt financing, the holders of debt would have priority over the holders of common stock, and the Company may be required to accept terms that restrict its ability to incur additional indebtedness and take other actions that would otherwise possibly not be in the interests of the Company's shareholders, forcing it to maintain specified liquidity or other ratios.
Accounting for Digital Currencies
The lack of U.S. Generally Accepted Accounting Principles (U.S. GAAP) instruction regarding the proper accounting treatment of digital currency assets has created uncertainty regarding the reporting and proper asset classification of digital currency holdings.  Management has exercised its business judgment in determining appropriate accounting treatment for the recognition of revenue from mining of digital currencies. Management, in conjunction with its outside public accountants and its auditors, has examined various factors surrounding the substance of the Company's operations and the available guidance published for public company accounting practices in Accounting Standards Codification. 

Initially, the Company undertook to record its digital currency assets at fair market value on receipt and disposition. Based on subsequent reviews of the available accounting guidance, the Company has concluded that its originally adopted accounting policy was in error and that its digital currencies should have been recorded at cost less impairment. The Company has since revised its treatment of its digital currency assets in line with this corrected reevaluation. This change in accounting policy did not have a material impact of the Company's previously reported condensed interim consolidated financial statements.

Consequentially, the Company presently accounts for its digital currency assets as indefinite life intangible assets. An intangible asset with an indefinite useful life is not amortized, but rather is assessed for impairment annually, or more frequently, when events or changes in circumstances occur which indicate that it is more likely than not that the indefinite-lived asset is impaired. Impairment exists when the carrying amount exceeds its fair value. In testing for impairment, the Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted. Realized gain or loss on the sale of digital currencies is included in other income or expenses in the Company’s statements of operations.
As of December 31, 2017, the Company held digital currencies valued at $200,164.  For the year ending December 31, 2017, mining revenue was only $172,959 and unrealized gains from digital currencies were only $27,205.  We considered these amounts clearly immaterial given total assets of $52,335,540 as of December 31, 2017 and the $19,970,932 net loss for the year ending December 31, 2017.  The U.S. Dollar spot price for bitcoin as of March 31, 2018 and June of 2018 declined from the previous quarterly periods and the Company recorded a $2,467,875 and a $511,170 loss related to the change in fair value of digital currencies for the three months ended March 31, 2018 and June 30, 2018, respectively.  Such change in the fair value of digital assets was recorded as a component of costs and expenses in our consolidated statements of operations and would have been categorized as an impairment loss under our updated policy with no impact on total costs and expenses for the six months ended June 30, 2018.  Accordingly, there was no material difference between our original accounting for our digital currency assets and recording them for cost less impairment.  Conversely, if there had been an increase in the conversion spot price of our digital currency assets to U.S. Dollars over these periods, our original accounting method would have shown corresponding increases in the book value of those assets; whereas, under the cost less impairment method, gains on assets are not recorded until those assets are sold, so our basis in our digital currency assets would have remained pegged to their lowest impairment value.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision, you should consider carefully consider the risks, uncertainties and forward-looking statements describedall risk factors set forth in the applicable prospectus supplement and the documents incorporated by reference in this prospectus, including the risk factors discussed under "Risk Factors"the heading “Risk Factors” in Item 1A of our most recent Form 10-Q for the period ended September 30, 2017 filed with the Securities and Exchange Commission (the "SEC") on November 13, 2017 and in Item 1A of our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 20162017, as amended, and each subsequent filed quarterly report on Form 10-Q and current reports on Form 8-K, which may be amended, supplemented or superseded from time to time by the other reports we file with the SEC on March 31, 2017, as amended as of April 27, 2017 and August 15, 2017, as well as informationin the future.

In addition to those risk factors incorporated by reference herein, the Company has identified the following uncertainties and risk factors which may affect our business:

The price of our common stock may be influenced by the market price of digital currencies, among other factors, which may be susceptible to wide swings in value.

Digital currency market prices, in particular that of bitcoin, which represents our primary digital currency asset, have experienced significant short- and long-term fluctuations in value. There is no assurance that the price of digital currencies (i.e. bitcoin) may not have an adverse effect on the price of our common stock, despite management’s best efforts to pursue the Company’s core businesses. This is because the value and price of our common stock, as determined by the investing public, may be influenced by future anticipated adoption or appreciation in value of digital currencies or the blockchain generally, factors over which the Company has little or no influence or control. The Company’s share price may also be subject to pricing volatility due to supply and demand factors associated with few or limited public company options for investment in the digital currency industry.

Digital currency market prices are determined primarily using data from various exchanges, over-the-counter markets, and derivative platforms. Furthermore, such prices may be subject to factors such as those that impact commodities, more so than business activities, which could be subjected to additional influence from fraudulent or illegitimate actors, real or perceived scarcity, and political, economic, regulatory or other conditions. Pricing may be the result of, and may continue to result in, speculation regarding future appreciation in the value of digital currencies, or the Company or its share price, inflating and making their market prices more volatile or creating “bubble” type risks.  As of the date of this prospectus, the trading price of bitcoin and other digital currencies has experienced significant decline and the trading price of our common stock has experienced a similar decline. If the trading price of the Company’s common stock declines below NASDAQ listing standards for an extended period our common stock could be suspended or delisted from the NASDAQ exchange.

Future sales and issuances of our equity securities or rights to purchase our equity securities would result in additional dilution of the percentage ownership of our stockholders.

Our stockholders may experience substantial dilution as we raise additional capital through issuances of equity securities. We may, from time to time, sell common stock, preferred stock, warrants, units, options or convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, preferred stock, warrants, units, options or convertible securities or other equity securities in more than one transaction, investors may be further diluted by subsequent sales. Management believes additional capital must be raised to continue executing the Company’s strategic plans. Management believes potential shareholder dilution resulting from the Company’s capital raising activities will be offset by increases in Company value and corresponding increases in the trading price of our common stock.  Management cannot, however, guarantee that such sales will not result in material dilution to our existing stockholders, and further notes that new investors could gain rights superior to existing stockholders.

The price of our common stock could be adversely affected by subpoenas issued to the Company by the Securities and Exchange Commission pertaining to an ongoing investigation.
As previously disclosed, on April 9, 2018, the Company received a subpoena from the Securities and Exchange Commission (the “SEC”) in connection with an ongoing investigation. The Company has endeavored to fully cooperate with this ongoing investigation. The ultimate outcome of the investigation and its potential impact on the Company cannot be ascertained at this time. Regardless of the ultimate outcome, cooperation with the investigation has entailed, and may continue to entail, significant legal costs and the diversion of management’s attention away from the Company’s core businesses, which could have an impact on the trading prices of the Company’s common stock.
Further, as previously disclosed, the Company received a letter from the SEC (the “Letter”) on July 30, 2018 by the SEC that it had issued an Order Directing Examination and Designating Officers Pursuant to Section 8(e) of the Securities Act of 1933 with respect to the following registration statements: (i) a Form S-8 filed on July 19, 2017 (File No. 333-219357); (ii) a Form S-3 filed January 5, 2018, and amended February 7, 2018 (File No. 333-222450); and (iii) a Form S-3 filed on July 10, 2018 (File No. 333-226111).  The Letter stated, “while the Section 8(e) examination is pending, the Division of Corporation Finance will not take any further action on the Registration Statements, and all communications with regard to the Registration Statements and the Section 8(e) examination should be made to the Commission’s Division of Enforcement.” The Company fully cooperated with the SEC’s examination and withdrew or terminated such registration statements on October 12, 2018. On October 22, 2018, the Company was notified by the SEC staff that the SEC had terminated the Section 8(e) examination with respect to the above-referenced registration statements.  The previously disclosed SEC investigation associated with the subpoena received by the Company on April 9, 2018 is still ongoing, however, and the Company is continuing to cooperate in that investigation.
Currently, there is relatively small use of bitcoins in the retail and commercial marketplace in comparison to relatively large use by speculators, thus contributing to price volatility that could adversely affect an investment in the Company.

A significant portion of bitcoin demand is generated by speculators and investors seeking to profit from the short or long-term holding of bitcoins. A lack of expansion by bitcoins into this prospectus. retail and commercial markets, or alternative uses, may result in increased volatility or a reduction in the price of bitcoin, either of which could adversely impact the market price of digital currencies and may cause the trading price of our common stock to decline.  Furthermore, no assurance can be made that, as markets for the exchange of digital currencies develop and mature, the inherent insubstantiality of stateless currency will not continue to contribute to the volatility of its conversion price to State-backed fiat currencies.

Banks and financial institutions may not provide banking services, or may cut off existing services, to businesses that provide digital currency related services or accept payment in the form of digital currencies, including financial institutions of investors in our securities.

The Company previously disclosed its agreement with SynapseFi and its banking partner, Evolve Bank and Trust, through the Company’s subsidiary, Logical Brokerage, on its periodic report on Form 8-K filed on October 29, 2018, in which SynapseFi and Evolve agreed to provide certain banking services to the Company’s planned digital currency exchange, RiotX.

A number of companies that provide digital currency related services have been unable to contract with banks or other similar financial institutions to provide such companies with banking services.  Similarly, a number of companies and individuals associated with digital currencies and the provision of digital currency related services have had their existing banking services relationships terminated as a result of their association with digital currencies. Accordingly, the Company recognizes that its relationships with banking institutions could be subject to reconsideration and even termination, depending on their internal controls and practices vis-à-vis digital currencies.
Many businesses and individuals in the digital currencies field may experience difficulty in finding banking services which may have an adverse effect on the usefulness of digital currencies as a payment system, and further, that such lack of broad based acceptance may cause further harm to the public perception of digital currencies. These acceptance issues pervade the market for digital currencies and could act as an artificial deflationary pressure on the price of our digital currency assets and the overall trading price of our common stock.
The lack of broad base acceptance of digital currencies by banking institutions could result in increased compliance costs, risk of loss, and adverse governmental regulatory action of our activities such that out business operations and projections may be significantly adversely affected.  This risk may also apply to underwriters, brokers, and ultimate holders of our securities, as our involvement in the digital currencies sector may be linked to our investors through our securities. Enforcement action by any governmental or quasi-governmental organization that prevents us from readily converting digital currencies into State-backed fiat currencies could have a material adverse effect on our Company.

If anywe are unable to attract major brokerage firms, we could have difficulty selling our common stock.

If we are unable to attract the interest of these risks were to occur, our business, financial condition or results of operations would likely suffer. In that event,major brokerage firms through the value of our securitiesCompany, we may be unable to secure their confidence and recommendation to purchase our common stock.  The absence of such coverage may depress or otherwise slow the development of a robust market for our common stock, slowing our ability to raise capital.

The online nature of the RiotX exchange will expose it to risks of third party hacking attacks, which, due to the nature of Blockchain technologies, may result in irreversible or unrecoverable losses to RiotX users.

The online marketplace has long been subject to hackers and other malicious actors.  The Company's business, and particularly its RiotX exchange, is an online-based platform and will be subject to these same hacking risks. Accordingly, RiotX is being developed with security measures to defend against such attacks and to provide as much security and reliability to its future end users as possible given current security protocols and technologies, but such efforts may ultimately be ineffective due to the highly sophisticated and evolving nature of cyber-attacks. The Company has written and maintains a cybersecurity policy that outlines an extensive list of controls and supervisory practices in place reasonably designed to diligently supervise the risks of unauthorized access or attack of its information technology systems, and to respond appropriately should unauthorized access or cyber-attack occur.  The Company, in conjunction with its third party vendors, will continually work to improve existing security protocols and develop new security techniques and software to address future threats to the RiotX exchange, its users and valuable assets.  The Company's policy of air-gapping its digital assets from the internet to the extent possible means that its digital currency assets should not be reached by an online penetration of its security framework, thereby limiting the impact of a hacking event on the overall Company.  The RiotX exchange will have similar air-gapping and private key protections for its users' digital currency wallets.  As such, similar hacking attacks should have limited success in illegally transferring user data and digital currency assets if they gain illegal access to the RiotX exchange system.


12

Although the Company will implement these anti-hacking measures, RiotX remains exposed to risks from: DDoS attacks to limit the availability of exchange services or otherwise disrupt normal operations; account takeover attempts in which RiotX users are targeted by hackers or other illegal actors to gain access to login credentials, which could allow the illicit user to transfer user assets held via RiotX or commit other fraud; targeted software exploits designed to take advantage of vulnerabilities and flaws in the underlying software components of the exchange, digital wallets, and web services provided to RiotX over which the Company has little to no control in order to gain access to or transfer of user digital currency assets; potential misdirection of funds and assets by online "spoofers" posing as RiotX representatives, by man in the middle interceptions of the digital transfers similar to wire-tapping, browser session tampering in which the user's internet service provider is compromised, and malware that is designed or may be designed to target the digital signal of digital currency exchanges in order to redirect exchanged assets away from their intended recipients; phishing activities in which user login credentials are stolen; natural disasters temporarily or permanently disabling our physical servers; human error and insider threats to our servers and the RiotX exchange; and other unforeseen or unforeseeable threats to the RiotX exchange.  The occurrence of any one or a number of these risk factors could have a material negative impact on our business, resulting in a decline and youin the trading price of shares of our common stock.  Should this occur, our investors could lose partsome or all of your investment.their investment in our common stock; accordingly, investors in our Company should seriously consider these risk factors when considering investing in our Company.
Regulatory action against existing bitcoin and other digital currency exchanges may have a detrimental effect on the acceptance and widespread use of our planned digital currency exchange, RiotX.

In recent years, a number of bitcoin exchanges have been closed by governmental regulatory action due to alleged fraud and security breaches.  Some investors were not compensated for the loss of their account balances on these exchanges.  While our planned exchange is being developed to be licensed by the appropriate U.S. governmental and quasi-governmental regulatory authorities prior to launch, its planned scope will make it a desirable target for malware, DDoS, and other hacking attacks, which could lead to regulatory backlash against RiotX. The Company is working with its regulators to ensure alignment with standards set for business in the same sector for compliance, fraud prevention, and cybersecurity.  The Company cannot, however, predict or prevent all future threats and acknowledges that digital currency exchanges are possibly exposed to the following risks: denial of service attacks, account takeover attempts, software exploits due to vulnerabilities and flaws, potential misdirection of funds and assets, phishing, natural disasters, human error, insider threats and other factors that can render the exchange of digital currency untrustworthy.

Additionally, international action against bitcoin exchanges has been harsh; China has moved to shut down all digital currency exchanges operating within its borders.  Until such action was announced, mainland China and Hong Kong were responsible for a majority of global digital currency transactions.  We are aware of the threat posed by governmental and quasi-governmental regulators to the short and long-term success of RiotX, and we have taken steps to mitigate these risks by working closely with U.S. and uncertainties we describe are notstate regulators to obtain all proper licenses and approvals prior to the only ones facing us. Additionallaunch of RiotX.  The Company cannot mitigate against, or even fully anticipate, all regulatory actions which may be taken against it or the digital currency sector as a whole in the future, and such risks not presently knownpose a threat to us or that we currently deem immaterial may also impairthe success of our business operations. In addition,Further, the Company's efforts to mitigate against hacking attacks are necessarily limited by the present knowledge of various malware designs and other hacking methods; the remains the possibility that future unforeseeable hacking techniques could harm RiotX. Furthermore, occurrence of these hacking attacks may trigger regulatory backlash, which could temporarily suspend or even shut down operation of RiotX. We believe such regulatory actions will be less common in the future as digital currencies continue to gain acceptance, however, such enforcement actions presently pose a risk to the value of our past financial performanceplanned exchange, RiotX, and to the trading price of our common stock. Should any of these risk factors (or other unforeseen risk factors) occur, the Company may suffer substantial material harm, which may have a negative effect on the trading price of our common stock. 

We may not have adequate recourse against third parties if our bitcoins and other digital currency assets are lost, stolen or destroyed.

The online nature of digital currencies such as bitcoins and their immutability poses a unique threat to their security.  We have implemented robust security measures to minimize the exposure of our digital currencies to such risks including, without limitation, cold storage procedures to “air-gap” our digital currency keys from the internet.  These measures are not perfect and improper access to and transfer of our digital current assets may still occur despite our security measures.  By their nature, bitcoin transactions are largely irreversible.  Our recourse in the event of theft or other loss is limited to our ability to secure restitution from the improper transferors or transferees of our digital currency assets.  Recovery from such individuals may be limited by a number of factors including, without limitation, our ability to locate and identify both the transferors and transferees.  This risk may pose a threat to the trading price of our common stock, and the occurrence of such an event could have a materially adverse effect on our business and operations.

The senior secured convertible promissory notes and warrants issued in connection with our recent private financing transactions are convertible or exercisable for shares of our common stock, which, upon conversion or exercise, will dilute the Company’s current shareholders’ equity value.

We issued senior secured convertible promissory notes and warrants in connection with a private financing completed on January 28, 2019, as previously reported on our current report on Form 8-K filed on February 02, 2019.  As previously disclosed, these notes and warrants are convertible into or exercisable for shares of our common stock.  To the extent such notes are converted and such warrants are exercised, additional shares of common stock will be issued, which will result in dilution to the holders of common stock.  Upon registration of such shares for resale on the public market, such conversion and exercise will increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public trading market could adversely affect the market trading price of the Company’s common stock.


13

We have not registered the shares of common stock issuable upon the conversion of the senior secured convertible promissory notes and upon exercise of the warrants we issued to our investors in connection with our recent private financing transaction under the Securities Act or any state securities laws at this time, and such registration may not be in place when an investor desires to convert such notes or exercise such warrants, thus precluding such investor from selling the conversion and warrant shares on the public market, in violation of our agreements.

We have not registered the shares of common stock issuable upon the conversion of the notes or the exercise of the warrants under the Securities Act or any state securities laws at this time. Under the terms of the registration rights agreements entered into in connection with the financing, we have agreed to file a reliable indicatorregistration statement under the Securities Act covering such shares and maintain a current prospectus relating to the common stock issuable upon the conversion of future performance,the notes and/or exercise of the warrants, until the expiration of the warrants in accordance with the provisions of the agreements with our investors. However, we can offer no assurance that we will be successful in obtaining an effective registration status to cover such issued securities that we will be able to do so if, for example, any facts or events arise which represent a fundamental change in the information set forth in such registration statement or prospectus, the financial statements contained or incorporated by reference therein are not current or correct or regulatory action prevents or delays our registration.  These warrants are subject to cashless exercise in an amount representing 100% coverage of the principal balance of the notes upon issuance and historical trends shouldare exercisable by the investors six months after the closing date of the financing, but before the fifth year anniversary of the financing. However, no warrant will be exercisable, and we will not be usedobligated to anticipate resultsissue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder or an exemption is available. If the issuance of the shares upon the conversion of the notes or the exercise of the warrants is not so registered or qualified or exempt from registration or qualification, our investors may declare that we have defaulted on our obligations under the financing agreements. This would entitle our investors to significant remedial rights under the financing agreements.  Accordingly, our failure to register the securities issuable upon conversion of the notes and exercise of the warrants may result in a material adverse effect to the future.  See "Forward-Looking Statements" below. Company.

19

 Sale through Underwriters or Dealers

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

Direct Sales and Sales through Agents

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

Delayed Delivery Contracts

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Continuous Offering Program

Without limiting the generality of the foregoing, we may enter into a continuous offering program equity distribution agreement with a broker-dealer, under which we may offer and sell shares of our common stock from time to time through a broker-dealer as our sales agent. If we enter into such a program, sales of the shares of common stock, if any, will be made by means of ordinary brokers’ transactions on the NASDAQ Capital Market at market prices, block transactions and such other transactions as agreed upon by us and the broker-dealer. Under the terms of such a program, we also may sell shares of common stock to the broker-dealer, as principal for its own account at a price agreed upon at the time of sale. If we sell shares of common stock to such broker-dealer as principal, we will enter into a separate agreement with such broker-dealer, and we will describe this agreement in a separate prospectus supplement or pricing supplement.

Market Making, Stabilization and Other Transactions

Unless the applicable prospectus supplement states otherwise, other than our common stock all securities we offer under this prospectus will be a new issue and will have no established trading market. We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Item 15. Indemnification of Directors and Officers.

Nevada Revised Statutes Sections 78.7502 and 78.751 provide us with the power to indemnify any of our directors and officers. The director or officer must have conducted himself/herself in good faith and reasonably believe that his/her conduct was in, or not opposed to, our best interests. In a criminal action, the director, officer, employee or agent must not have had reasonable cause to believe his/her conduct was unlawful.
 
Under Nevada Revised Statutes Section 78.751, advances for expenses may be made by agreement if the director or officer affirms in writing that he/she believes he/she has met the standards and will personally repay the expenses if it is determined such officer or director did not meet the standards.

Our Articles of Incorporation provide that our officers and directors shall be indemnified and held harmless to the fullest extent legally permissible under the laws of the State of Nevada against all expenses, liability and loss (including attorneys' fees, judgments, fines and amounts paid or to be paid in settlement) reasonably incurred or suffered by them in connection with any civil, criminal, administrative or investigative action, suit or proceeding related to their service as an officer or director. Such right of indemnification shall be a contract right which may be enforced in any manner desired by such person. We must pay the expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by us. Such right of indemnification shall not be exclusive of any other right which such directors or officers may have or hereafter acquire.

Our Articles of Incorporation provide that we may adopt bylaws to provide at all times the fullest indemnification permitted by the laws of the State of Nevada, and may purchase and maintain insurance on behalf of any of officers and directors. The indemnification provided in our Articles of Incorporation shall continue as to a person who has ceased to be a director, officer, employee or agent, and shall inure to the benefit of the heirs, executors and administrators of such person.

Our Bylaws provide that a director or officer shall have no personal liability to us or our stockholders for damages for breach of fiduciary duty as a director or officer, except for damages for breach of fiduciary duty resulting from (a) acts or omissions which involve intentional misconduct, fraud, or a knowing violation of law, or (b) the payment of dividends in violation of Nevada Revised Statutes Section 78.3900.78.300.

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.
