Equity [Abstract]
Preferred Stock [Text Block]	Note 12. Series A Convertible Preferred Stock (restated) On November 2, 2012, the Company closed a private placement sale of 1,380,362 shares of Series A Convertible Preferred Stock (“Preferred Stock”), (including 2,760,724 warrants to purchase MGT Common stock) for an aggregate of $4.5 million. This transaction was approved by the Exchange on October 26, 2012. The Preferred Stock will be convertible into the Company's Common stock at a fixed price of $3.26 per share and carry a 6% dividend. The warrants have a five-year life and are exercisable at $3.85 per share. Total issuance cost for this private placement was $88. Significant terms of the Preferred Stock, as specified in the Certificate of Designation are as follows: Cash Maintenance: The Company shall maintain a cash balance of at least $2,000 as long as at least 345,092 shares of Preferred Stock remains outstanding. As of December 31, 2012, 1,380,362 shares of the Preferred Stock remains outstanding. In February and March 2013, 241,748 and 30,000 shares of the Company’s Series A Convertible Preferred Stock were converted into 241,748 and 30,000 shares, of the Company’s common stock, respectively. In April 2013, 1,123,809 shares of the Preferred Stock were converted into 1,125,763 shares of the Company’s Common stock, which included 1,954 shares of accrued interest on the Preferred Stock. Conversion Option: At any time and from time to time on or after the Effective Date, the Preferred Stock shall be convertible (in whole or in part), at the option of the Holder, into such number of fully paid and non-assessable shares of Common stock as is determined by dividing (x) the aggregate Stated Value of $3.26 per shares (“Stated Value”) of Preferred Stock that are being converted plus any accrued but unpaid dividends thereon as of such date that the Holder elects to convert by (y) the Conversion Price ($3.26) then in effect on the date (the “Conversion Date”). Dividends: The Preferred Stock shall pay a six percent (6%) annual dividend on the outstanding Preferred Stock, payable quarterly on March 31, June 30, September 30 and December 31 of each year (the “Dividend Date”), with the first dividend payable for the period commencing on the Issuance Date. The Company has the option to pay each quarterly dividend in cash or additional shares of Preferred Stock (the "Dividend Shares"). For the year ended December 31, 2012, the Company issued 14,404 Dividend Shares, in connection with this Preferred Stock dividend. Liquidation preference: Upon the liquidation, dissolution or winding up of the business of the Corporation, whether voluntary or involuntary, each holder of Preferred Stock shall be entitled to receive, for each share thereof, a preferential amount in cash equal to (and not more than) the Stated Value (the “Liquidation Amount”) plus all accrued and unpaid dividends. The Preferred Stock Certificate of Designation and Warrant agreement (“Warrants”) each contain a fundamental transactions clause that provides for the conditional redemption of these instruments under certain circumstances that are not within the Company’s sole control. Management has therefore concluded that the Preferred Stock requires temporary equity classification in accordance with ASC 480-10-S99 “Accounting for Redeemable Equity Instruments” at its allocated value and the warrants require classification at fair value. When the Preferred Stock and Warrants were issued, the fair value of the Warrants exceeded the proceeds received from the sale and issuance of the Preferred Stock and Warrants. The Warrants were recorded at their fair value and the excess over the proceeds received was recorded as a deemed dividend. Changes in the fair value of the Warrants at each reporting date are included in the statement of operations. The carrying amount of the Preferred Shares requires no further adjustment unless and until the conditional redemption events are probable. The Company does not consider the conditional redemption events to be probable, as these events refer to fundamental change of control situations that do not currently exist, in the opinion of management. Accordingly, management concluded that the conversion option embedded in the preferred shares does not require bifurcation from the host contract, as the Preferred Stocks have the characteristics of a residual interest and therefore are clearly and closely related to the Common stocks issuable upon the exercise of the conversion option. Further, since the issuance date fair value of the warrants exceeded the proceeds received from the sale and issuance of the Preferred Stock, accounting recognition of the beneficial conversion feature was not required. The warrants were recorded at fair value as of October 29, 2012 of $6,731 based upon the following Black Scholes Model (“BSM”) to value warrants containing circumstances that are not within the Company’s sole control: risk free rate 0.760%; expected term five (5) years; annual volatility 75.0%; exercise price $3.85, adjusted market value of $3.98 per share. The adjusted market value was determined based on market conditions for our common shares, characterized by significant price volatility when compared to seasoned issuers. The Company expects that our share price will continue to be more volatile for the indefinite future. The volatility is attributable to a several factors, most notably the fact that our common shares are thinly traded. Share Price is one of the inputs needed to determine the fair value of derivative instruments, as used in the BSM. The Company feels that the share price volatility would distort a BSM calculation if based on a single day’s closing price, thereby dissuading us from utilizing the closing price on October 26, 2012. The Company has determined that a more representative measurement would be to utilize an average of the daily weighted average stock price of the Company’s Common stock for the 30 days prior to the deal close. This calculation minimizes the impact of specific daily news or market trading distortions caused by an imbalance of orders on a single day. On December 31, 2012, the warrants were re-measured at fair value of $6,364, based upon the following BSM inputs: risk free rate 0.760%; expected term five (5) years; annual volatility 75.0%; exercise price $3.85, closing stock price of $3.86. The Company recorded a gain of $365, caused by the change in fair value of its derivative liability from inception through December 31, 2012. In November 2012, in connection with the sale of the Preferred Stock, the Company was required to enter into investor/public relations service agreements, with terms of seven, ten and twelve months. Compensation under the agreements includes cash consideration of $444, the issuance of 100,000 shares of Preferred Stock and 400,000 warrants to purchase MGT Common stock. Issuance of Preferred Stock and warrants to service providers as compensation for services are subject to shareholder approval. No shares were approved or issued as of December 31, 2012. Under the terms of the agreements, there are no penalties or liabilities to the Company if approval is not received. For the year ended December 31, 2012, the Company expensed $79, relating to the cash consideration under the agreements. One agreement was mutually terminated in January 2013, reducing the remaining cash consideration due by $108. In connection with the sale of the Preferred Stock, the Company entered into a registration rights agreement with the investors agreeing to file a registration statement within 60 days of the closing and to have the registration statement declared effective within 150 days of the closing if the registration statement is not subject to a full review and within 180 days of the closing if the registration statement is subject to a full review. The Company filed a Registration Statement (Registrant No. 333-185284) with the SEC on November 30, 2012, which was declared effective on January 11, 2013.
