Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1. Organization and Basis of Presentation Organization MGT Capital Investments, Inc. (“MGT” or the “Company”) was incorporated in Delaware in 2000. MGT was originally incorporated in Utah in 1977. MGT is comprised of the parent company and its wholly owned subsidiary MGT Sweden AB. MGT’s corporate office is located in Durham, North Carolina. On February 27, 2019, the Company’s stockholders approved an increase in the Company’s authorized common shares from 125,000,000 to 2,500,000,000 and the Company filed an amendment to its Certificate of Incorporation with the state of Delaware to reflect this change. On June 4, 2019, the Company filed a registration statement on Form S-1 covering up to 76,558,643 shares of common stock the Company may sell from time to time. On June 25, 2019, this registration was declared effective by the Securities and Exchange Commission (“SEC”). Through November 14, 2019, the Company sold 55,000,000 shares of its common stock under this registration statement for gross proceeds of $1,804. Cryptocurrency mining Following a review of its Bitcoin mining operations in early 2019, the Company determined to consolidate its activities in Company-owned and managed facilities. Central to this strategy was the purchase of land in LaFayette, GA and the entry into a favorable contract for electricity there in the second quarter of 2019. Located adjacent to a utility substation, the several acre property has access to over 20 megawatts (MW) of low-cost power. The facility will accommodate shipping containers racked with miners with individual capacities of up to 1 MW. The Company began Bitcoin mining at its LaFayette facility in late September 2019, using a newly designed container solution with a capacity of 456 Bitmain S9 miners or 300 Bitmain S17 miners. The property now has three of these containers onsite, awaiting the deployment of 320 S17 Pro miners that have been delivered by Bitmain, as well as MGT’s previously ordered 1,100 S17 miners, expected by mid-December 2019. By the end of November 2019, the Company expects delivery of two POD5 containers, each able to house 360 S17 miners. Including all hardware purchases to date, MGT projects a total of 1,475 new generation Bitcoin miners in operation in five containers at year end 2019. The machines collectively are rated at a total of approximately 80 Ph/s in computational power and will require an electric load of 4.0 MW. Phase one of the physical facility in LaFayette is substantially complete with five transformers installed with 12.5 MW of total load capacity and property improvements in place, such as access roads, security fencing, workshop, network wiring and underground high voltage electrical feeder lines. The Company’s agreements with third-party hosting facilities have been reduced to 1,200 S9 miners in Colorado Springs, and a location in Coshocton, Ohio, where MGT operates 576 S9 miners housed in the first production model of the Pod5 container, as further described in Note 9. In September 2019, the Company also terminated all third-party management agreements. With the ongoing transition to the new generation of Bitcoin miners, the Company has been selling its inventory of S9 miners, rather than enter into short term uneconomic hosting arrangements. To date, the Company has sold approximately 2,500 units. Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10–Q and Rule 10 of Regulation S–X. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America. However, in the opinion of the management of the Company, all adjustments necessary for a fair presentation of the financial position and operating results have been included in these statements. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10–K for the fiscal year ended December 31, 2018, as filed with the SEC on April 16, 2019. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for any subsequent quarters or for the year ending December 31, 2019.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Going Concern and Management's Plans	Note 2. Going Concern and Management’s Plans The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of September 30, 2019, the Company had incurred significant operating losses since inception and continues to generate losses from operations. As of September 30, 2019, the Company had an accumulated deficit of $413,303. As of September 30, 2019 and October 31, 2019, MGT’s cash and cash equivalents were $2,113 and $1,077, respectively. Management’s plans include the consolidation of its activities in Company-owned and managed facilities, executing on its expansion model to secure low cost power and grow its cryptocurrency assets. Based on current budget assumptions, the Company believes that it will be able to meet its operating expenses and obligations for one year from the date these unaudited condensed consolidated financial statements are issued. The Company will need to raise additional funding to grow its operations and to pay current maturities of debt. There can be no assurance however that the Company will be able to raise additional capital when needed, or at terms deemed acceptable, if at all. Such factors raise substantial doubt about the Company’s ability to sustain operations for at least one year from the issuance of these unaudited condensed consolidated financial statements. Management’s plans, including the consolidation of its activities in Company-owned and managed facilities, the raising of additional capital and potentially curtailing its operations, alleviate such substantial doubt. The accompanying unaudited condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies Principles of consolidation The unaudited condensed consolidated financial statements include the accounts of MGT and MGT Sweden AB. All intercompany transactions and balances have been eliminated. Use of estimates and assumptions and critical accounting estimates and assumptions The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, and also affect the amounts of revenues and expenses reported for each period. Actual results could differ from those which result from using such estimates. Management utilizes various other estimates, including but not limited to determining the estimated lives of long-lived assets, determining the potential impairment of long-lived assets, the fair value of warrants issued, the fair value of conversion features, the recognition of revenue, the valuation allowance for deferred tax assets and other legal claims and contingencies. The results of any changes in accounting estimates are reflected in the financial statements in the period in which the changes become evident. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period that they are determined to be necessary. Prior Period Financial Statement Correction of an Immaterial Misstatement During the first quarter of 2019, the Company identified certain adjustments required to correct balances within notes payable, accretion of debt discount, and the gain on extinguishment of debt relating to the modification to the June 2018 Note (as defined in Note 5) that had occurred on December 10, 2018. The Company had incorrectly calculated the fair value of the June 2018 Note as the date of its modification, which in turn, led the Company to calculate an incorrect gain on extinguishment and an incorrect accretion of debt discount. The errors discovered resulted in an overstatement of the Company’s notes payable balance of $566 as of December 31, 2018, and an overstatement of the accretion of debt discount of $14 and understatement on the gain on extinguishment of $580 for the year ended December 31, 2018. Based on an analysis of Accounting Standards Codification (“ASC”) 250 – “Accounting Changes and Error Corrections” (“ASC 250”), Staff Accounting Bulletin 99 – “Materiality” (“SAB 99”) and Staff Accounting Bulletin 108 – “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”), the Company determined that these errors were immaterial to the previously-issued consolidated financial statements, and as such no restatement was necessary. Correcting prior year financial statements for immaterial errors would not require previously filed reports to be amended. Such correction may be made the next time the registrant files the prior year financial statements. Accordingly, the misstatements were corrected during the period ended March 31, 2019 in the accompanying consolidated balance sheet as of December 31, 2018. The effect on these revisions on the Company’s consolidated balance sheet as of December 31, 2018 is as follows: As previously reported at December 31, 2018 Adjustment As revised at December 31, 2018 Notes payable, net of discount $ 1,851 $ (566 ) $ 1,285 Total current liabilities 2,398 (566 ) 1,832 Total liabilities 2,398 (566 ) 1,832 Accumulated deficit (405,285 ) 566 (404,719 ) Total stockholders’ deficit (1,875 ) 566 (1,309 ) Revenue recognition The Company’s primary revenue stream is related to the mining of digital currencies. The Company derives its revenue by solving “blocks” to be added to the blockchain and providing transaction verification services within the digital currency network of Bitcoin, commonly termed “cryptocurrency mining.” In consideration for these services, the Company receives digital currency (“Coins”). The Coins are recorded as revenue, using the average spot price of Bitcoin on the date of receipt. The Coins are recorded on the balance sheet as an intangible digital asset valued at the lower of cost or net realizable value. Net realizable value adjustments, to adjust the value of Coins to market value, is included in cost of revenue on the Company’s consolidated statement of operations. Further, any gain or loss on the sale of Coins would be recorded to costs of revenue. Costs of revenue include hosting fees, equipment and infrastructure depreciation, rent, net realizable value adjustments, and electricity costs. The Company also recognized revenue from its management agreements through their termination in August and September 2019, as further described in Note 9. The Company received a fee from each management agreement based on the amount of Bitcoin mined and was reimbursed for any electricity costs incurred to run the Bitcoin mining machines it managed in its facility. Additionally, the Company has machines located in facilities in Ohio and Colorado. The Company receives an allocation of profits from the Ohio facility. For the Colorado location, the Company recognizes Bitcoin revenue and recognizes hosting fees as cost of revenue. The Company also has machines in a temporary facility in Georgia whereby the Company recognizes Bitcoin revenue and recognizes hosting fees as cost of revenue. These machines will be moved to MGT’s permanent location in LaFayette, GA during Q4 2019. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight–line method on the various asset classes over their estimated useful lives, which range from one to ten years when placed in service. The cost of repairs and maintenance is expensed as incurred; major replacements and improvements are capitalized. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in income in the year of disposition. In connection with the Company’s plans to consolidate its activities in Company-owned and managed facilities, the Company has entered into agreements to acquire Bitcoin mining machines and containers to house the mining machines requiring upfront deposits. Deposits on such purchases are classified as Other Assets. Upon delivery, installation and full payment, the assets will be classified as property and equipment on the consolidated balance sheet. Income taxes The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”. ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and established for all the entities a minimum threshold for financial statement recognition of the benefit of tax positions and requires certain expanded disclosures. The provision for income taxes is based upon income or loss after adjustment for those permanent items that are not considered in the determination of taxable income. Deferred income taxes represent the tax effects of differences between the financial reporting and tax basis of the Company’s assets and liabilities at the enacted tax rates in effect for the years in which the differences are expected to reverse. The Company evaluates the recoverability of deferred tax assets and establishes a valuation allowance when it is more likely than not that some portion or all the deferred tax assets will not be realized. Management makes judgments as to the interpretation of the tax laws that might be challenged upon an audit and cause changes to previous estimates of tax liability. In management’s opinion, adequate provisions for income taxes have been made. If actual taxable income by tax jurisdiction varies from estimates, additional allowances or reversals of reserves may be necessary. Loss per share Basic loss per share is calculated by dividing net loss applicable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted loss per share is calculated by dividing the net loss attributable to common shareholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of unvested restricted shares, convertible debt stock warrants and stock options, are not reflected in diluted net loss per share because such potential shares are anti–dilutive due to the Company’s net loss. Accordingly, the computation of diluted loss per share for the three- and nine-month periods ended September 30, 2019 excludes 850,000 unvested restricted shares, 6,000,000 shares issuable under stock options, 97,575,510 shares issuable upon the conversion of convertible debt, and 68,452,381 shares under preferred stock. The computation of diluted loss per share for the three and nine months ended September 30, 2018 excludes 3,555,000 unvested restricted shares, 6,000,000 shares issuable under stock options, and 6,227,975 shares issuable under warrants. Stock–based compensation The Company recognizes compensation expense for all equity–based payments in accordance with ASC 718 “Compensation – Stock Compensation”. Under fair value recognition provisions, the Company recognizes equity–based compensation net of an estimated forfeiture rate and recognizes compensation cost only for those shares expected to vest over the requisite service period of the award. Restricted stock awards are granted at the discretion of the compensation committee of the board of directors of the Company. These awards are restricted as to the transfer of ownership and generally vest over the requisite service periods, typically over a 12 to 24-month period (vesting on a straight–line basis). The fair value of a stock award is equal to the fair market value of a share of the Company’s common stock on the grant date. The fair value of an option award is estimated on the date of grant using the Black–Scholes option valuation model. The Black–Scholes option valuation model requires the development of assumptions that are inputs into the model. These assumptions are the expected stock volatility, the risk–free interest rate, the expected life of the option, the dividend yield on the underlying stock and the expected forfeiture rate. Expected volatility is calculated based on the historical volatility of the Company’s common stock over the expected term of the option. Risk–free interest rates are calculated based on continuously compounded risk–free rates for the appropriate term. Determining the appropriate fair value model and calculating the fair value of equity–based payment awards requires the input of the subjective assumptions described above. The assumptions used in calculating the fair value of equity–based payment awards represent management’s best estimates, which involve inherent uncertainties and the application of management’s judgment. The Company is required to estimate the expected forfeiture rate and recognize expense only for those shares expected to vest. The Company accounts for share–based payments granted to non–employees in accordance with ASC 505–50, “Equity Based Payments to Non–Employees.” The Company determines the fair value of the stock–based payment as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more readily determinable. If the fair value of the equity instruments issued is used, it is measured using the stock price and other measurement assumptions as of the earlier of either (1) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (2) the date at which the counterparty’s performance is complete. The fair value of unvested equity instruments is re-measured each reporting period and such re-measured value is amortized over the requisite remaining service period. Gain (Loss) on Modification/Extinguishment of Debt In accordance with ASC 470, a modification or an exchange of debt instruments that adds or eliminates a conversion option that was substantive at the date of the modification or exchange is considered a substantive change and is measured and accounted for as extinguishment of the original instrument along with the recognition of a gain/loss. Additionally, under ASC 470, a substantive modification of a debt instrument is deemed to have been accomplished with debt instruments that are substantially different if the present value of the cash flows under the terms of the new debt instrument is at least 10 percent different from the present value of the remaining cash flows under the terms of the original instrument. A substantive modification is accounted for as an extinguishment of the original instrument along with the recognition of a gain/loss. Recent accounting pronouncements Management does not believe that any recently issued, but not yet effective accounting pronouncements, when adopted, will have a material effect on the accompanying unaudited condensed consolidated financial statements, other than those disclosed below. In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The guidance is effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, ASU 2018-07 is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. On January 1, 2019, the Company adopted ASU 2018-07, which has not had a material effect on the Company’s financial statements. In February 2016, the FASB issued ASU 2016-02 Leases which requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases with terms greater than 12 months. In July 2018, the FASB issued ASU 2018-10 Leases, Codification Improvements and ASU 2018-11 Leases, Targeted Improvements, to provide additional guidance for the adoption of ASU 2016-02. ASU 2018-10 clarifies certain provisions and corrects unintended applications of the guidance such as the application of implicit rate, lessee reassessment of lease classification, and certain transition adjustments that should be recognized to earnings rather than to stockholders’ (deficit) equity. ASU 2018-11 provides an alternative transition method and practical expedient for separating contract components for the adoption of ASU 2016-02. ASU 2016-02, ASU 2018-10, ASU 2018-11, (collectively, “Topic 842”) are effective for fiscal years beginning after December 15, 2018, with early adoption permitted. On January 1, 2019, the Company adopted Topic 842 and made the following elections: ● The Company did not elect the hindsight practical expedient, for all leases. ● The Company elected the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs for all leases. ● In March 2018, the FASB approved an optional transition method that allows companies to use the effective date as the date of initial application on transition. The Company elected this transition method, and as a result, will not adjust its comparative period financial information or make the newly required lease disclosures for periods before the effective date. ● The Company elected to not separate lease and non-lease components, for all leases. On January 1, 2019, the Company recorded a Right of Use Asset of $87, a corresponding Lease Liability of $84 and a corresponding cumulative adjustment to accumulated deficit of $3 in accordance with Topic 842. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which is intended to improve the effectiveness of fair value measurement disclosures. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this pronouncement. In August 2018, the FASB issued ASU 2018-15, Intangible – Goodwill and Other – Internal-Use Software (“ASU 2018-15”), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this pronouncement. Management’s evaluation of subsequent events The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Based upon the review, other than what is described in Note 11 – Subsequent Events, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the unaudited condensed consolidated financial statements.

Debt Disclosure [Abstract]
Notes Payable	Note 5. Notes Payable On May 23, 2018, the Company entered into a securities purchase agreement with two accredited investors, pursuant to which the Company issued $840 in unsecured promissory notes for aggregate consideration of $700 (the “May 2018 Notes”). The outstanding balance of the May 2018 Notes was to be made in nine equal monthly installments beginning July 23, 2018. The May 2018 Notes were scheduled to mature on March 23, 2019. Subject to the terms and conditions set forth in the May 2018 Notes, the Company may prepay all or any portion of the outstanding balance at any time without pre-payment penalty. Upon the occurrence of an event of default, the outstanding balance of the May 2018 Notes shall immediately increase to 120% of the outstanding balance immediately prior to the event of default and become immediately due and payable. On June 1, 2018, the Company entered into a note purchase agreement with an accredited investor, pursuant to which the Company issued an unsecured promissory note in the amount of $3,600 (the “June 2018 Note”) for consideration of $3,000. The outstanding balance of the June 2018 Note was to be made in nine equal monthly installments beginning August 1, 2018. The June 2018 Note was scheduled to mature on April 1, 2019. Subject to the terms and conditions set forth in the June 2018 Note, the Company may prepay all or any portion of the outstanding balance at any time without pre-payment penalty. Upon the occurrence of an event of default, the outstanding balance of the June 2018 Note shall immediately increase to 120% of the outstanding balance immediately prior to the event of default and become immediately due and payable. On December 6, 2018, the Company entered into a note purchase agreement with an accredited investor, pursuant to which the Company issued an unsecured promissory note in the amount of $598 (the “December 2018 Note”) for consideration of $500. The outstanding balance of the December 2018 Note had a maturity date of May 6, 2019 and was paid in full in March 2019. The December 2018 Note bore interest at a rate of 8% per annum and, subject to the terms and conditions set forth in the December 2018 Note, the Company was permitted to prepay all or any portion of the outstanding balance at any time without pre-payment penalty. On January 7, 2019, and again on March 28, 2019 the Company entered into amendments to one of the May 2018 Notes. Pursuant to the amendments, the borrower has agreed to extend the maturity date of the note to July 15, 2019 and does not require the Company to make its monthly installment payments due from December 2018, through March 2019, provided that the Company makes all installment payments for the months thereafter beginning April 15, 2019. Installment payments shall be paid in cash unless the Company elects to make payments in shares of the Company’s common stock, in which case the number of shares to be issued will be based on the lowest VWAP of the Company’s common stock during the preceding twenty trading days multiplied by 70%, or any lower price made available to any other holder of the Company’s securities. In consideration of these amendments, the Company incurred extension fees payable to the borrower of $121. On January 28, 2019, the Company entered into an amendment to the June 2018 Note. Pursuant to the amendment, the borrower has agreed to extend the maturity date to October 1, 2019 and not require the Company to make its installment payment due under the Note Purchase Agreement during January, February, and March 2019. The Company and the borrower have agreed that the Company is to pay all installment payments in cash unless both the Company and the borrower agree to make payments in shares of the Company’s common stock, in which case the number of shares to be issued will be based on the lowest intra-day trade price of the Company’s common stock during the preceding twenty trading days multiplied by 70%. In consideration of this amendment, the Company incurred an extension fee payable to the borrower of $527. Because the January 2019 and March 2019 amendments were considered a substantive change, the Company has treated the modification as an extinguishment of debt and determined the gain or loss on the exchange of instruments. Based on the analysis performed, the Company determined that there was a gain on extinguishment of debt of $1,275. On April 9, 2019, the Company entered an amendment to one of its May 2018 Notes to (a) forego the installment payments due on February 23, 2019 and March 23, 2019, (b) extend the maturity date of the note to August 15, 2019, and (c) include a substantial conversion feature allowing the debt holder, in its sole discretion, to have the right to convert the April 15, 2019 monthly payment, and each payment thereafter, into shares of the Company’s common stock. The number of shares to be issued will be based on the lower of: i) 70% of the lowest intra-day price of the Company’s common stock during the preceding twenty (20) trading days, or ii) any lower price that is made available to any other holder of the Company’s securities, whether by sale or conversion, on the date of a conversion notice. In exchange for the amendment, the Company compensated the holder of the note by increasing the outstanding principal due by $50. The Company accounted for this amendment as an extinguishment of debt and recorded a gain of $127. On May 10, 2019, the original holders of the Company’s May 2018 Notes assigned and sold all notes to Oasis Capital, LLC (“Oasis Capital”). On the same date, the Company and Oasis Capital executed a letter agreement to amend the terms of the May 2018 Notes allowing Oasis Capital to convert the total outstanding principal amount of $421 into shares of the Company’s common stock, at a price equal to 70% of the lowest trading price during the 20 days preceding the conversion dates, or any lower price made available to any other holder of the Company’s securities. This amendment also eliminated the Company’s mandatory monthly amortization payments and extended the maturity of the May 2018 Notes until August 15, 2019. After such date, and within 10 business days, any outstanding balance shall be satisfied, at the Company’s election, either with cash, common stock conversion or any combination thereof. On May 15, 2019, the Company issued 10,568,087 shares of its common stock pursuant to the full conversion of the May 2018 Notes. On May 10, 2019, the Company executed a letter agreement with the holder of the June 2018 Note to amend the terms of the June 2018 Note allowing the holder to covert the total outstanding principal amount of $3,159 into shares of the Company’s common stock, at a price equal to 70% of the lowest trading price during the 20 day period preceding the conversion dates, or any lower price made available to any other holder of the Company’s securities. This amendment also eliminates the Company’s mandatory monthly amortization payments and extends the maturity of the June 2018 Note until December 15, 2019. After such date, and within 10 business days, any outstanding balance shall be satisfied, at the Company’s election, either with: cash, common stock conversion, or any combination thereof. The Company accounted for this amendment as an extinguishment of debt and recorded a gain of $1,004. During the three months ended September 30, 2019, the Company issued 16,654,170 shares of its common stock upon the conversion of $450 in outstanding principal by the holder and during the nine months ended September 30, 2019 issued 63,310,326 shares of its common stock upon the conversion of $1,725 in outstanding principal by the holder reducing the outstanding principal to $1,434 as of September 30, 2019. The holder of the June 2018 Note also acquired 17,500,000 shares of the Company’s common stock on April 12, 2019, is an affiliate of the acquirer of 150 shares of the Preferred Shares acquired on April 12, 2019 and acquired 10 shares of the Preferred Shares on July 15, 2019, see Note 7 below, and are collectively subject to a maximum beneficial ownership of 9.99%. Of the 160 shares of Preferred Stock acquired by the affiliate, 115 shares are issued and outstanding as of September 30, 2019. Notes payable consisted of the following: As of September 30, 2019 Principal Discount Net June 2018 Note $ 1,434 $ (495 ) $ 939 Total notes payable $ 1,434 $ (495 ) $ 939 As of December 31, 2018 Principal Discount Net May 2018 Notes $ 400 $ (25 ) $ 375 June 2018 Note 2,448 (1,803 ) 645 December 2018 Note 351 (86 ) 265 Total notes payable $ 3,199 $ (1,914 ) $ 1,285 During the three months ended September 30, 2019 and 2018, the Company recorded accretion of debt discount of $946 and $0, respectively.

Equity [Abstract]
Common Stock, Preferred Stock and Warrants	Note 7. Common Stock, Preferred Stock and Warrants Common stock Equity Purchase Agreement under Form S-3 From January 1, 2019 through April 16, 2019, the Company sold shares of its common stock pursuant to an equity purchase agreement with Oasis Capital. The equity purchase agreement was entered on August 30, 2018 and was amended on November 30, 2018, whereby the Company could issue and sell to Oasis Capital from time to time up to $50,000 of the Company’s common stock that was registered with the SEC under a registration statement on Form S–3. Subject to the terms of the equity purchase agreement, the Company provided notice (a “Put Notice”) requiring Oasis Capital to purchase a number of shares (the “Put Shares”) of the common stock equal to the lesser of $500 and 200% of the average trading volume of the common stock in the ten trading days immediately preceding the date of such Put Notice. The terms also provided the purchase price for such Put Shares to be the lowest traded price on a principal market for any trading day during the five trading days either following or beginning on the date on which Oasis Capital receives delivery of the Put Shares, multiplied by 95.0%. During the three and nine months ended September 30, 2019, the Company issued 23,900,000 and 67,000,000 shares of its common stock in exchange for $1,575 and $3,731, respectively. Of the proceeds received during the three months ended March 31, 2019, $354 was applied directly as payment against the December 2018 Note. On April 16, 2019, the Company became ineligible to issue shares under its registration statement on Form S-3 as the aggregate market value of the Company’s common stock held by non-affiliates was below the regulatory threshold of $75,000. In connection with this ineligibility, the equity purchase agreement was terminated. Equity Purchase Agreement under Form S-1 On June 3, 2019, the Company entered into an equity purchase agreement with Oasis Capital, whereby the Company shall have the right, but not the obligation, to direct Oasis Capital to purchase shares of the Company’s common stock (the “New Put Shares”) in an amount in each instance up to the lesser of $1,000 or 250% of the average daily trading volume by delivering a notice to Oasis Capital (the “New Put Notice”). The purchase price (the “Purchase Price”) for the New Put Shares shall equal 95% of the one lowest daily volume weighted average price on a principal market during the five trading days immediately following the date Oasis receives the New Put Shares via DWAC associated with the applicable New Put Notice (the “Valuation Period”). The closing of a New Put Notice shall occur within one trading day following the end of the respective Valuation Period, whereby (i) Oasis shall deliver the Investment Amount (as defined below) to the Company by wire transfer of immediately available funds and (ii) Oasis shall return surplus New Put Shares if the value of the New Put Shares delivered to Oasis causes the Company to exceed the maximum commitment amount. The Company shall not deliver another New Put Notice to Oasis within ten trading days of a prior New Put Notice. The “Investment Amount” means the aggregate Purchase Price for the New Put Shares purchased by Oasis, minus clearing costs payable to Oasis’s broker or to the Company’s transfer agent for the issuance of the New Put Shares. The shares issuable under the equity purchase agreement are registered with the SEC under a registration statement on Form S-1 that was declared effective on June 25, 2019 and are subject to a maximum beneficial ownership by Oasis Capital of 9.99%. During the three months ended September 30, 2019, the Company issued 40,000,000 shares of its common stock in exchange for $1,442, net of deferred offering costs of $71. No shares were issued under the Form S-1 prior to July 1, 2019. Other Common Stock Sales and Issuances On April 12, 2019, the Company entered into a purchase agreement with an accredited investor whereby it sold 17,500,000 shares of its common stock for $525 pursuant to the Company’s then-effective registration statement on Form S-3. The holder of these shares is also the holder of the June 2018 Note and an affiliate of the acquirer of 150 shares of the Preferred Shares acquired on April 12, 2019 described below. During the three months ended March 31, 2019, the Company issued 160,500 shares of its common stock to consultants in exchange for services. These services were valued based upon the value of the shares issued of $60. No shares were issued to consultants during the second and third quarters of 2019. During the three and nine months ended September 30, 2018, the Company issued 360,500 and 1,539,051 shares of its common stock, respectively, to consultants in exchange for services. These services were valued based upon the value of the shares issued of $322 and $2,036, respectively. In connection with the termination of its management agreements, see Note 9 below, the Company issued 10,250,000 shares of its common stock to acquire 2,000 S9 miners from its former partners. The S9 miners were valued at $312, based on the trading value of the Company’s common stock on the date each management agreement was terminated. Preferred Stock On January 11, 2019, the Company’s Board of Directors approved the authorization of 10,000 shares of Series B Preferred Stock with a par value of $0.001 (“Series B Preferred Shares”). The holders of the Series B Preferred Shares shall be entitled to receive, when, as, and if declared by the Board of Directors of the Company, out of funds legally available for such purpose, dividends in cash at the rate of 12% of the stated value per annum on each Series B Preferred Share. Such dividends shall be cumulative and shall accrue without interest from the date of issuance of the respective share of the Series B Preferred Shares. Each holder shall also be entitled to vote on all matters submitted to stockholders of the Company and shall be entitled to 55,000 votes for each Series B Preferred Share owned at the record date for the determination of stockholders entitled to vote on such matter or, if no such record date is established, at the date such vote is taken or any written consent of stockholders is solicited. In the event of a liquidation event, any holders of the Series B Preferred Shares shall be entitled to receive, for each Series B Preferred Shares, the stated value in cash out of the assets of the Company, whether from capital or from earnings available for distribution to its stockholders. The Series B Preferred Shares are not convertible into shares of the Company’s common stock. On April 12, 2019, the Company’s Board of Directors approved the authorization of 200 shares of Series C Convertible Preferred Stock with a par value of $0.001 and a stated value of $10,000 per share (“Preferred Shares”). The holders of the Preferred Shares have no voting rights, receive no dividends, and are entitled to a liquidation preference equal to the stated value. At any time prior to the one-year anniversary from the issuance date, the Company may redeem the Preferred Shares at 1.4 times the stated value, following which the Company may redeem the Preferred Shares at 1.2 times the stated value. Each Preferred Share is convertible into shares of the Company’s common stock in an amount equal to the greater of: (a) 200,000 shares of common stock or (b) the amount derived by dividing the stated value by the product of 0.7 times the market price of the Company’s common stock, defined as the lowest trading price of the Company’s common stock during the ten day period preceding the conversion date. The holder may not convert any Preferred Shares if the total amount of shares held, together with holdings of its affiliates, following a conversion exceeds 9.99% of the Company’s common stock. The Company has accounted for the beneficial conversion feature of the Preferred Shares, convertible at 0.7 times the market price of the Company’s common stock, as a deemed dividend of $859 for the three months ended June 20, 2019 and $46 for the three months ended September 30, 2019, measured as the difference between the conversion price of the Preferred Shares and the fair value of the underlying common stock. The common shares issued upon conversion have been registered under the Company’s then-effective registration statement on Form S-3. On April 12, 2019, the Company sold 190 Preferred Shares for $1,890, net of issuance costs and on July 15, 2019 sold 10 Preferred Shares for $100. During the three months ended June 30, 2019, holders of the preferred shares converted 50 of their Preferred Shares into 14,077,092 shares of common stock. During the three months ended September 30, 2019, the holder of the preferred stock converted 35 of their shares Preferred Shares into 13,528,575 shares of common stock. Given the right of redemption is solely at the option of the Company, the Preferred Shares are not considered mandatorily redeemable, and as such are classified in shareholders’ equity on the Company’s condensed consolidated balance sheet. Warrants The following table summarizes information about shares issuable under warrants outstanding during the nine months ended September 30, 2019: Warrant Weighted Weighted Intrinsic Outstanding at January 1, 2019 5,477,975 $ 1.01 Issued - - Exercised (4,000,000 ) $ 1.12 Expired or cancelled (1,477,975 ) $ 0.72 Outstanding and exercisable at September 30, 2019 - $ - - $ - On June 5, 2019, the Company entered into an agreement with a holder of a warrant for 10,000 shares of common stock, whereby the holder agreed to sell the warrant back to the Company for a nominal amount. The Company subsequently cancelled the warrant. On May 9, 2019, the Company entered into a modification agreement with the holder of six separate warrants. Under the terms of the initial warrant agreements, the holder was entitled to purchase 4,000,000 shares of the Company’s common stock at prices of between $0.50 per share and $2.00 per share at various times through September 2022. Under the terms of the modification agreement, the holder was permitted to exercise all 4,000,000 warrants at a price of $0.03 per share, or $120. The Company accounted for this modification as a down-round feature under the guidance of ASC 260-10-30, whereby the change in fair value of the warrants before and after the down-round was triggered was recorded as a deemed dividend in the amount of $101. During the three months ended September 30, 2019, the Company entered into agreements with three holders of warrants for 1,450,000 shares of common stock, whereby the holders agreed to sell the warrants back to the Company for $14. The Company subsequently canceled the warrants.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9. Commitments and Contingencies Bitcoin Mining Agreements On May 20, 2019, the Company entered into an agreement with a third-party consultant whereby the consultant would advise and consult with the Company on certain business and financial matters relating to crypto-currency mining. The Company engaged the consultant to: (1) assist in locating at least 5 acres of real property in Georgia within close proximity to a fully operational electric substation with a minimum of 15 MW of available capacity, subject to approval by the power company, (2) negotiate a power rate between the Company and a power company, (3) assist in the identification, purchase, and delivery of transformers required to serve the containerized mining systems, (4) successfully install the aforementioned transformers, and (5) obtain an electrical permit and successfully inspect all electrical infrastructure between the container and substation. The consulting agreement was valued at $400 and such amount was transferred to a third-party escrow account, payable to the consultant upon successful achievement of defined milestones. Upon achievement, the value of the milestone is recorded as a component of general and administrative expenses with an offsetting reduction to prepaid expense. During the second and third quarters of 2019, $200 and $50 in milestone achievements were earned, respectively, and the remaining $150 is recorded as a prepaid expense as of September 30, 2019. On October 23, 2018, the Company entered into a hosting agreement (“Colorado Hosting Agreement”) with a hosting facility in Colorado, whereby the service provider provides a facility to host Bitcoin computing servers. The Colorado Hosting Agreement has been amended several times and currently provides for the hosting of 1,200 miners, a reduction of a security deposit from $204 to $66 and a termination date of December 3, 2020. Because the price of Bitcoin steadily decreased in 2018 and throughout the first quarter 2019, the Company decided it was not economically responsible to commence mining under this hosting arrangement until May 2019 when Bitcoin mining economics started to improve. On May 10, 2019, the Company, entered into a hosting agreement (“Ohio Hosting Agreement”) relating to the generation of Bitcoin mining revenues at a facility located in Coshocton, Ohio (the “Facility”) for a term that is the earlier of (i) two years, or (ii) when the parties determine that the Bitcoin mining business at the Facility is uneconomical. The Ohio Hosting Agreement was amended in September 2019 and currently provides for the hosting of 576 miners and a reduction of the security deposit from $240 to $80. Under the terms of the Ohio Hosting Agreement, the Company agreed to provide the necessary hardware to conduct Bitcoin mining at the Facility. The service provider agreed, among other things, to provide necessary hosting capacity, equipment, infrastructure and electricity to operate the mining hardware at the Facility. A third-party operator agreed, among other things, to and maintain the Facility in accordance with prudent industry standards and to maintain the hardware. The service provider is required to disburse on a monthly basis: (i) the total electricity costs to the utility provider; (ii) 10% of Gross Profits (as defined in the Ohio Hosting Agreement) to the operator; (iii) the Net Profits (as defined in the Ohio Hosting Agreement) such that 10% of all Gross Profits (as defined in the Ohio Hosting Agreement) shall be paid to the Company, 40% of all Gross Profits shall be paid to service provider, and 40% of all Gross Profits will be paid into the Security Deposit account until such time as the Security Deposit is paid in full; and (iv) subsequent to the satisfaction of the Security Deposit, Net Profits equally between the Company and the service provider. During the three and nine months ended September 30, 2019, the Company recognized $78 and $148 under these agreements, respectively, a portion of which was accounted for under the management agreements that were terminated during the three months ended September 30, 2019. Management Agreements On May 2, 2019, the Company entered into amended management agreements with two accredited investors, Deep South Mining LLC and BDLM, LLC (the “Users”). The Users’ miners were reconnected, and mining Bitcoin was resumed upon execution of these agreements. Due to wear and tear, the parties acknowledge the Users’ Bitcoin Hardware consist of 1,800 Bitmain Antminer S9 mining computers, collectively. The Company entered into two Settlement and Termination Agreements (the “Settlement Agreements”) to its existing management agreements with the Users on August 31, 2019. Under the terms of the Settlement Agreements, the Company will pay the Users a percentage of profits (“User Distribution”) of Bitcoin mining as defined in the Settlement Agreements for a period not to exceed 16 months. The estimated present value of the User Distributions of $337 was recorded as termination expense with an offsetting liability on August 31, 2019. Since two of the components of the User Distribution, Bitcoin price and Difficulty, as defined in the Settlement Agreements, are based on market conditions, the liability will be marked-to-market on a quarterly basis and any changes will be recorded in the statement of operations. As of September 30, 2019, the Company recognized a gain on the change in the fair value of $135 based on a reduction of Bitcoin price and an increase in Difficulty, reducing the liability to $194. Beginning on December 31, 2019 and for a period of 12 months thereafter and conditioned on other events as defined in the Settlement Agreements, the parties may unilaterally terminate the Settlement Agreements for a one-time payment of $270,000, collectively, by the Company. Additionally, the Company acquired the 1,800 Antminer S-9 Bitcoin miners owned by the Users for 9,000,000 restricted shares of the Company’s common stock valued at $279. On September 30, 2019, the Company terminated its remaining management agreement with a third party for a one-time payment of $27 and the acquisition of 200 Antminer S-9 Bitcoin miners owned by the third party for 1,250,000 restricted shares of the Company’s commons stock valued at $33. On August 14, 2018, the Company entered into a collaborative venture with a third-party cryptocurrency miner to develop a fully contained crypto currency mining pod (the “POD5 Agreement”). Pursuant to the POD5 Agreement, the Company will assist with the design and development of the pods (“POD5 containers”). The Company will retain naming rights to the pods and receive royalty payments from the third party in exchange for providing capital as well as engineering and design expertise. During the three and nine months ended September 30, 2019, the Company received royalties and recognized revenue of $7 under this agreement. Legal On August 28, 2019, a shareholder derivative action was filed by shareholder Tyler Tomczak against the Company and certain of its directors, officers and shareholders in New York state court, alleging breach of fiduciary duties, waste and unjust enrichment and seeking declaratory relief and damages (the “Tomczak Derivative Action”). The underlying allegations in the Tomczak Derivative Action largely repeat the allegations of wrongdoing in the 2018 Securities Class Actions (as defined below). The Company-related defendants’ time to respond to the Tomczak Derivative Action has been extended until December 31, 2019. On September 11, 2019, a shareholder derivative action was filed by shareholder Arthur Aviles against the Company and certain of its directors, officers and shareholders in New York state court, alleging breach of fiduciary duties, waste and unjust enrichment and seeking declaratory relief and damages (the “Aviles Derivative Action”). The underlying allegations in the Aviles Derivative Action largely repeat the allegations of wrongdoing in the 2018 Securities Class Actions. The Company-related defendants’ time to respond to the Aviles Derivative Action has been extended until December 31, 2019. In September 2018 and October 2018, various shareholders of the Company filed putative class action lawsuits against the Company, its then former Chief Executive Officer and certain of its individual officers and shareholders, alleging violations of federal securities laws and seeking damages (the “2018 Securities Class Actions”). The 2018 Securities Class Action followed and referenced the allegations made against the Company’s then former Chief Executive Officer and others in the SEC Action. The first putative class action lawsuit was filed on September 28, 2018, in the United States District Court for the District of New Jersey, and alleges that the named defendants engaged in a pump-and-dump scheme to artificially inflate the price of the Company’s stock and that, as a result, defendants’ statements about the Company’s business and prospects were materially false and misleading and/or lacked a reasonable basis at relevant times. The second putative class action was filed on October 9, 2018, in the United States District Court for the Southern District of New York and makes similar allegations. On May 28, 2019, the parties to the Class Actions entered into a binding settlement term sheet, and on September 24, 2019, the parties entered into a stipulation of settlement. On August 7, 2019, the lead plaintiff in the first class action filed a notice and order of voluntary dismissal with prejudice, and on October 11, 2019, the lead plaintiff in the second class action filed an unopposed motion for preliminary approval of the proposed class action settlement. On January 24, 2017, the Company was served with a summons and complaint filed by plaintiff shareholder Atul Ojha in New York state court against certain officers and directors of the Company, and naming the Company as a nominal defendant. The lawsuit is styled as a derivative action (the “Ojha Derivative Action”) and was originally filed (but not served on any defendant) on October 15, 2016. The Ojha Derivative Action substantively alleges that the defendants, collectively or individually, inadequately managed the business and assets of the Company resulting in the deterioration of the Company’s financial condition. The Ojha Derivative Action asserts claims including, but not limited to, breach of fiduciary duties, unjust enrichment and waste of corporate assets. On February 27, 2017, the parties to the Ojha Derivative Action executed a stipulated stay of proceedings pending resolution of a class action filed in 2016 (the “2016 Securities Class Action”). Shortly after issuance of the February 27, 2018, ruling dismissing the 2016 Securities Class Action, the parties to the Ojha Derivative Action agreed to extend the stay indefinitely, with the plaintiff having the option to vacate the stay on thirty days’ notice. On October, 28, 2019, the parties agreed to extend the stay indefinitely, with the plaintiff having the option to vacate the stay on thirty days’ notice. Should the plaintiff seek to vacate the stay, the Company will address and defend the Ojha Derivative Action. On December 12, 2018, a shareholder derivative action was filed by shareholder Bob Thomas against the Company and certain of its current and former directors, officers and shareholders in New York state court, alleging breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste and seeking declaratory relief and damages (the “Thomas Derivative Action”). The underlying allegations in the Thomas Derivative Action largely repeat the allegations of wrongdoing in the 2018 Securities Class Actions. Based on communications between the Company’s counsel and plaintiff’s counsel in the Thomas Derivative Action, plaintiff intended to seek consolidation of this case with the Ojha Derivative Action, and then to stay the consolidated derivative action pending resolution of the 2018 Securities Class Actions. The Company-related defendants’ time to respond to the Thomas Derivative Action has been extended until thirty days after the Court rules on plaintiff’s motion. On October 18, 2019 counsel for the plaintiffs in the Ojha Derivative Action advised the Company that plaintiffs had filed such a motion, and the court had denied it, but neither the motion nor the decision were ever served on the Company. Counsel for the Company is currently engaged in discussions with the counsel for plaintiffs about setting a new deadline for the Company-related defendants to respond to the complaint. On October 31, 2019, the Company, and its current officers and directors, received subpoenas from the SEC requesting information, including but not limited to, with respect to risk factors contained in certain of the Company’s filings with the SEC, any investigations by any government agency into Robert B. Ladd and certain other matters related to the Company’s securities. The time period covered by the subpoenas is January 1, 2019 through the date of issuance of the subpoenas. The Company and its current officers and directors are cooperating with the SEC’s request. The Company is unable to predict what action, if any, might be taken in the future by the SEC or any other governmental authority as a result of the subpoenas. The Company believes the claims in the actions filed against the Company are without merit and intends to vigorously defend against these actions.

Subsequent Events	Note 11. Subsequent Events The Company has evaluated the impacts of subsequent events through November 14, 2019 and has determined that no such events occurred that were required to be reflected in the unaudited condensed consolidated financial statements, except as described within the above notes and described below. Through November 14, 2019, the Company issued 15,000,000 shares of its common stock under the equity purchase agreement for gross proceeds of $264. Through November 14, 2019, the holder of the June 2018 Note converted $125 of debt principle into 8,503,401 shares of common stock, reducing the outstanding principal to $1,309. On October 29, 2019, the Company purchased 320 Bitmain S17 Pro Antminers which were received in early November 2019. The purchase of the S17 Pro Antminers is in addition to the previously announced purchase of 1,100 Bitmain S17 Antminers. The Company expects delivery of that batch prior to mid-December of this year. The containers to house these 1,100 miners include two POD5 containers and are expected onsite by the end of November 2019. Due to contractual provisions of the 1,100 Bitmain S17 order, MGT took advantage of a material price reduction, and chose to allocate some of the savings to the new order of S17 Pro Antminers.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of consolidation The unaudited condensed consolidated financial statements include the accounts of MGT and MGT Sweden AB. All intercompany transactions and balances have been eliminated.
Use of Estimates and Assumptions and Critical Accounting Estimates and Assumptions	Use of estimates and assumptions and critical accounting estimates and assumptions The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, and also affect the amounts of revenues and expenses reported for each period. Actual results could differ from those which result from using such estimates. Management utilizes various other estimates, including but not limited to determining the estimated lives of long-lived assets, determining the potential impairment of long-lived assets, the fair value of warrants issued, the fair value of conversion features, the recognition of revenue, the valuation allowance for deferred tax assets and other legal claims and contingencies. The results of any changes in accounting estimates are reflected in the financial statements in the period in which the changes become evident. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period that they are determined to be necessary.
Prior Period Financial Statement Correction of an Immaterial Misstatement	Prior Period Financial Statement Correction of an Immaterial Misstatement During the first quarter of 2019, the Company identified certain adjustments required to correct balances within notes payable, accretion of debt discount, and the gain on extinguishment of debt relating to the modification to the June 2018 Note (as defined in Note 5) that had occurred on December 10, 2018. The Company had incorrectly calculated the fair value of the June 2018 Note as the date of its modification, which in turn, led the Company to calculate an incorrect gain on extinguishment and an incorrect accretion of debt discount. The errors discovered resulted in an overstatement of the Company’s notes payable balance of $566 as of December 31, 2018, and an overstatement of the accretion of debt discount of $14 and understatement on the gain on extinguishment of $580 for the year ended December 31, 2018. Based on an analysis of Accounting Standards Codification (“ASC”) 250 – “Accounting Changes and Error Corrections” (“ASC 250”), Staff Accounting Bulletin 99 – “Materiality” (“SAB 99”) and Staff Accounting Bulletin 108 – “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”), the Company determined that these errors were immaterial to the previously-issued consolidated financial statements, and as such no restatement was necessary. Correcting prior year financial statements for immaterial errors would not require previously filed reports to be amended. Such correction may be made the next time the registrant files the prior year financial statements. Accordingly, the misstatements were corrected during the period ended March 31, 2019 in the accompanying consolidated balance sheet as of December 31, 2018. The effect on these revisions on the Company’s consolidated balance sheet as of December 31, 2018 is as follows: As previously reported at December 31, 2018 Adjustment As revised at December 31, 2018 Notes payable, net of discount $ 1,851 $ (566 ) $ 1,285 Total current liabilities 2,398 (566 ) 1,832 Total liabilities 2,398 (566 ) 1,832 Accumulated deficit (405,285 ) 566 (404,719 ) Total stockholders’ deficit (1,875 ) 566 (1,309 )
Revenue Recognition	Revenue recognition The Company’s primary revenue stream is related to the mining of digital currencies. The Company derives its revenue by solving “blocks” to be added to the blockchain and providing transaction verification services within the digital currency network of Bitcoin, commonly termed “cryptocurrency mining.” In consideration for these services, the Company receives digital currency (“Coins”). The Coins are recorded as revenue, using the average spot price of Bitcoin on the date of receipt. The Coins are recorded on the balance sheet as an intangible digital asset valued at the lower of cost or net realizable value. Net realizable value adjustments, to adjust the value of Coins to market value, is included in cost of revenue on the Company’s consolidated statement of operations. Further, any gain or loss on the sale of Coins would be recorded to costs of revenue. Costs of revenue include hosting fees, equipment and infrastructure depreciation, rent, net realizable value adjustments, and electricity costs. The Company also recognized revenue from its management agreements through their termination in August and September 2019, as further described in Note 9. The Company received a fee from each management agreement based on the amount of Bitcoin mined and was reimbursed for any electricity costs incurred to run the Bitcoin mining machines it managed in its facility. Additionally, the Company has machines located in facilities in Ohio and Colorado. The Company receives an allocation of profits from the Ohio facility. For the Colorado location, the Company recognizes Bitcoin revenue and recognizes hosting fees as cost of revenue. The Company also has machines in a temporary facility in Georgia whereby the Company recognizes Bitcoin revenue and recognizes hosting fees as cost of revenue. These machines will be moved to MGT’s permanent location in LaFayette, GA during Q4 2019.
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight–line method on the various asset classes over their estimated useful lives, which range from one to ten years when placed in service. The cost of repairs and maintenance is expensed as incurred; major replacements and improvements are capitalized. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in income in the year of disposition. In connection with the Company’s plans to consolidate its activities in Company-owned and managed facilities, the Company has entered into agreements to acquire Bitcoin mining machines and containers to house the mining machines requiring upfront deposits. Deposits on such purchases are classified as Other Assets. Upon delivery, installation and full payment, the assets will be classified as property and equipment on the consolidated balance sheet.
Income Taxes	Income taxes The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”. ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and established for all the entities a minimum threshold for financial statement recognition of the benefit of tax positions and requires certain expanded disclosures. The provision for income taxes is based upon income or loss after adjustment for those permanent items that are not considered in the determination of taxable income. Deferred income taxes represent the tax effects of differences between the financial reporting and tax basis of the Company’s assets and liabilities at the enacted tax rates in effect for the years in which the differences are expected to reverse. The Company evaluates the recoverability of deferred tax assets and establishes a valuation allowance when it is more likely than not that some portion or all the deferred tax assets will not be realized. Management makes judgments as to the interpretation of the tax laws that might be challenged upon an audit and cause changes to previous estimates of tax liability. In management’s opinion, adequate provisions for income taxes have been made. If actual taxable income by tax jurisdiction varies from estimates, additional allowances or reversals of reserves may be necessary.
Loss Per Share	Loss per share Basic loss per share is calculated by dividing net loss applicable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted loss per share is calculated by dividing the net loss attributable to common shareholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of unvested restricted shares, convertible debt stock warrants and stock options, are not reflected in diluted net loss per share because such potential shares are anti–dilutive due to the Company’s net loss. Accordingly, the computation of diluted loss per share for the three- and nine-month periods ended September 30, 2019 excludes 850,000 unvested restricted shares, 6,000,000 shares issuable under stock options, 97,575,510 shares issuable upon the conversion of convertible debt, and 68,452,381 shares under preferred stock. The computation of diluted loss per share for the three and nine months ended September 30, 2018 excludes 3,555,000 unvested restricted shares, 6,000,000 shares issuable under stock options, and 6,227,975 shares issuable under warrants.
Stock-based Compensation	Stock–based compensation The Company recognizes compensation expense for all equity–based payments in accordance with ASC 718 “Compensation – Stock Compensation”. Under fair value recognition provisions, the Company recognizes equity–based compensation net of an estimated forfeiture rate and recognizes compensation cost only for those shares expected to vest over the requisite service period of the award. Restricted stock awards are granted at the discretion of the compensation committee of the board of directors of the Company. These awards are restricted as to the transfer of ownership and generally vest over the requisite service periods, typically over a 12 to 24-month period (vesting on a straight–line basis). The fair value of a stock award is equal to the fair market value of a share of the Company’s common stock on the grant date. The fair value of an option award is estimated on the date of grant using the Black–Scholes option valuation model. The Black–Scholes option valuation model requires the development of assumptions that are inputs into the model. These assumptions are the expected stock volatility, the risk–free interest rate, the expected life of the option, the dividend yield on the underlying stock and the expected forfeiture rate. Expected volatility is calculated based on the historical volatility of the Company’s common stock over the expected term of the option. Risk–free interest rates are calculated based on continuously compounded risk–free rates for the appropriate term. Determining the appropriate fair value model and calculating the fair value of equity–based payment awards requires the input of the subjective assumptions described above. The assumptions used in calculating the fair value of equity–based payment awards represent management’s best estimates, which involve inherent uncertainties and the application of management’s judgment. The Company is required to estimate the expected forfeiture rate and recognize expense only for those shares expected to vest. The Company accounts for share–based payments granted to non–employees in accordance with ASC 505–50, “Equity Based Payments to Non–Employees.” The Company determines the fair value of the stock–based payment as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more readily determinable. If the fair value of the equity instruments issued is used, it is measured using the stock price and other measurement assumptions as of the earlier of either (1) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (2) the date at which the counterparty’s performance is complete. The fair value of unvested equity instruments is re-measured each reporting period and such re-measured value is amortized over the requisite remaining service period.
Gain (Loss) On Modification/extinguishment of Debt	Gain (Loss) on Modification/Extinguishment of Debt In accordance with ASC 470, a modification or an exchange of debt instruments that adds or eliminates a conversion option that was substantive at the date of the modification or exchange is considered a substantive change and is measured and accounted for as extinguishment of the original instrument along with the recognition of a gain/loss. Additionally, under ASC 470, a substantive modification of a debt instrument is deemed to have been accomplished with debt instruments that are substantially different if the present value of the cash flows under the terms of the new debt instrument is at least 10 percent different from the present value of the remaining cash flows under the terms of the original instrument. A substantive modification is accounted for as an extinguishment of the original instrument along with the recognition of a gain/loss.
Recent Accounting Pronouncements	Recent accounting pronouncements Management does not believe that any recently issued, but not yet effective accounting pronouncements, when adopted, will have a material effect on the accompanying unaudited condensed consolidated financial statements, other than those disclosed below. In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The guidance is effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, ASU 2018-07 is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. On January 1, 2019, the Company adopted ASU 2018-07, which has not had a material effect on the Company’s financial statements. In February 2016, the FASB issued ASU 2016-02 Leases which requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases with terms greater than 12 months. In July 2018, the FASB issued ASU 2018-10 Leases, Codification Improvements and ASU 2018-11 Leases, Targeted Improvements, to provide additional guidance for the adoption of ASU 2016-02. ASU 2018-10 clarifies certain provisions and corrects unintended applications of the guidance such as the application of implicit rate, lessee reassessment of lease classification, and certain transition adjustments that should be recognized to earnings rather than to stockholders’ (deficit) equity. ASU 2018-11 provides an alternative transition method and practical expedient for separating contract components for the adoption of ASU 2016-02. ASU 2016-02, ASU 2018-10, ASU 2018-11, (collectively, “Topic 842”) are effective for fiscal years beginning after December 15, 2018, with early adoption permitted. On January 1, 2019, the Company adopted Topic 842 and made the following elections: ● The Company did not elect the hindsight practical expedient, for all leases. ● The Company elected the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs for all leases. ● In March 2018, the FASB approved an optional transition method that allows companies to use the effective date as the date of initial application on transition. The Company elected this transition method, and as a result, will not adjust its comparative period financial information or make the newly required lease disclosures for periods before the effective date. ● The Company elected to not separate lease and non-lease components, for all leases. On January 1, 2019, the Company recorded a Right of Use Asset of $87, a corresponding Lease Liability of $84 and a corresponding cumulative adjustment to accumulated deficit of $3 in accordance with Topic 842. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which is intended to improve the effectiveness of fair value measurement disclosures. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this pronouncement. In August 2018, the FASB issued ASU 2018-15, Intangible – Goodwill and Other – Internal-Use Software (“ASU 2018-15”), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this pronouncement.
Management's Evaluation of Subsequent Events	Management’s evaluation of subsequent events The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Based upon the review, other than what is described in Note 11 – Subsequent Events, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the unaudited condensed consolidated financial statements.

Description on Cryptocurrency mining			Following a review of its Bitcoin mining operations in early 2019, the Company determined to consolidate its activities in Company-owned and managed facilities. Central to this strategy was the purchase of land in LaFayette, GA and the entry into a favorable contract for electricity there in the second quarter of 2019. Located adjacent to a utility substation, the several acre property has access to over 20 megawatts (MW) of low-cost power. The facility will accommodate shipping containers racked with miners with individual capacities of up to 1 MW. The Company began Bitcoin mining at its LaFayette facility in late September 2019, using a newly designed container solution with a capacity of 456 Bitmain S9 miners or 300 Bitmain S17 miners. The property now has three of these containers onsite, awaiting the deployment of 320 S17 Pro miners that have been delivered by Bitmain, as well as MGT's previously ordered 1,100 S17 miners, expected by mid-December 2019. By the end of November 2019, the Company expects delivery of two POD5 containers, each able to house 360 S17 miners. Including all hardware purchases to date, MGT projects a total of 1,475 new generation Bitcoin miners in operation in five containers at year end 2019. The machines collectively are rated at a total of approximately 80 Ph/s in computational power and will require an electric load of 4.0 MW. Phase one of the physical facility in LaFayette is substantially complete with five transformers installed with 12.5 MW of total load capacity and property improvements in place, such as access roads, security fencing, workshop, network wiring and underground high voltage electrical feeder lines. The Company's agreements with third-party hosting facilities have been reduced to 1,200 S9 miners in Colorado Springs, and a location in Coshocton, Ohio, where MGT operates 576 S9 miners housed in the first production model of the Pod5 container, as further described in Note 9.

Debt instrument conversion description

On May 10, 2019, the original holders of the Company's May 2018 Notes assigned and sold all notes to Oasis Capital, LLC (“Oasis Capital”).

Debt instrument conversion description

On May 10, 2019, the Company executed a letter agreement with the holder of the June 2018 Note to amend the terms of the June 2018 Note allowing the holder to covert the total outstanding principal amount of $3,159 into shares of the Company's common stock, at a price equal to 70% of the lowest trading price during the 20 day period preceding the conversion dates, or any lower price made available to any other holder of the Company's securities.

Debt extinguishment amendment description

On April 9, 2019, the Company entered an amendment to one of its May 2018 Notes to (a) forego the installment payments due on February 23, 2019 and March 23, 2019, (b) extend the maturity date of the note to August 15, 2019, and (c) include a substantial conversion feature allowing the debt holder, in its sole discretion, to have the right to convert the April 15, 2019 monthly payment, and each payment thereafter, into shares of the Company's common stock. The number of shares to be issued will be based on the lower of: i) 70% of the lowest intra-day price of the Company's common stock during the preceding twenty (20) trading days, or ii) any lower price that is made available to any other holder of the Company's securities, whether by sale or conversion, on the date of a conversion notice. In exchange for the amendment, the Company compensated the holder of the note by increasing the outstanding principal due by $50. The Company accounted for this amendment as an extinguishment of debt and recorded a gain of $127.

Agreement period, description	On May 20, 2019, the Company entered into an agreement with a third-party consultant whereby the consultant would advise and consult with the Company on certain business and financial matters relating to crypto-currency mining. The Company engaged the consultant to: (1) assist in locating at least 5 acres of real property in Georgia within close proximity to a fully operational electric substation with a minimum of 15 MW of available capacity, subject to approval by the power company, (2) negotiate a power rate between the Company and a power company, (3) assist in the identification, purchase, and delivery of transformers required to serve the containerized mining systems, (4) successfully install the aforementioned transformers, and (5) obtain an electrical permit and successfully inspect all electrical infrastructure between the container and substation. The consulting agreement was valued at $400 and such amount was transferred to a third-party escrow account, payable to the consultant upon successful achievement of defined milestones. Upon achievement, the value of the milestone is recorded as a component of general and administrative expenses with an offsetting reduction to prepaid expense. During the second and third quarters of 2019, $200 and $50 in milestone achievements were earned, respectively, and the remaining $150 is recorded as a prepaid expense as of September 30, 2019.

Agreement period, description			On October 23, 2018, the Company entered into a hosting agreement ("Colorado Hosting Agreement") with a hosting facility in Colorado, whereby the service provider provides a facility to host Bitcoin computing servers. The Colorado Hosting Agreement has been amended several times and currently provides for the hosting of 1,200 miners, a reduction of a security deposit from $204 to $66 and a termination date of December 3, 2020. Because the price of Bitcoin steadily decreased in 2018 and throughout the first quarter 2019, the Company decided it was not economically responsible to commence mining under this hosting arrangement until May 2019 when Bitcoin mining economics started to improve.
