Subsequent Events [Abstract]
Subsequent Events	On March 19, 2021, the Company and Greenidge Generation Holdings, Inc. (“Greenidge”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) providing, among other things, that on the terms and subject to the conditions set forth therein, Greenidge will acquire the Company through a merger of a wholly owned subsidiary of Greenidge with and into the Company (the “Merger”). The Company will survive as a wholly owned subsidiary of Greenidge. The Merger is subject to customary closing conditions, including the approval of the shareholders of the Company. The Merger is expected to close during the third quarter of 2021. Effective as of the closing of the Merger, all outstanding shares of the Company’s common stock and all outstanding restricted stock units and options to purchase shares of the Company’s common stock will be cancelled and converted into the right to receive shares of Class A Common Stock of Greenidge (the “Greenidge Common Stock”). Following completion of the Merger, it is expected that the Company’s stockholders and holders of stock options and restricted stock units collectively will own approximately 8% of the outstanding shares of the Greenidge Common Stock, and existing Greenidge stockholders are expected to own approximately 92% of the Greenidge Common Stock. If the Merger Agreement is terminated under certain circumstances, the Company will be required to pay a termination fee. In connection with and as a condition to Greenidge's willingness to enter into the Merger Agreement, on March 19, 2021, the Company entered into a subscription agreement (the "Subscription Agreement") with 210 Capital, LLC (“210 Capital”), pursuant to which 210 Capital subscribed for and purchased, and the Company issued and sold, an aggregate of 3,909,871 shares of the Company’s Common Stock for a purchase price of $1.85 per share, for aggregate gross proceeds to the Company of $7,233,261.35. Pursuant to and subject to the terms and conditions set forth in the Subscription Agreement, among other things, and only upon any termination of the Merger Agreement, the Company has agreed that, not later than the earlier of (i) thirty (30) days following the date of such termination and (ii) December 31, 2021, it will increase the size of the Company’s board of directors in order to appoint two individuals designated by 210 Capital to the board of directors for a term expiring at the next succeeding annual meeting of the Company’s stockholders.
