Ladies and Gentlemen:
We have acted as counsel to Greenidge Generation Holdings Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing by the Company of a post-effective Amendment No. 3 to its Registration Statement on Form S-1 on Form S-3 (File No. 333-259247) (as amended or supplemented, the “Registration Statement”) on September 30, 2022 with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration by the Company of the offer and sale from time to time by the selling stockholders covered by the Registration Statement (the “Selling Stockholders”) of (i) up to 6,966,974 outstanding shares of class A common stock, par value $0.0001 (“Common Stock”), of the Company, held by certain of the Selling Stockholders (the “Common Stock Resale Shares”), and (ii) up to 3,491,500 shares of Common Stock (the “Class B Conversion Shares”) issuable to certain Selling Stockholders upon conversion of 3,491,500 shares of class B common stock, par value $0.0001, of the Company (the “Class B Common Stock”), as described in the prospectus forming a part of the Registration Statement (the “Prospectus”).
In rendering the opinions expressed below, we have reviewed originals or copies of the following documents (the “Opinion Documents”):

| (b) | The Registration Statement; |
| (d) | Such other corporate records of the Company, certificates of public officials and of officers of the Company and agreements and other documents as we have deemed necessary as a basis for the opinion expressed below. |
In our review of the Opinion Documents, we have assumed:
| (a) | The genuineness of all signatures; |
| (b) | The authenticity of the originals of the documents submitted to us; |
| (c) | The conformity to authentic originals of any documents submitted to us as copies; and |
| (d) | As to matters of fact, the truthfulness of the representations made in the Opinion Documents, and in certificates of public officials and officers of the Company. |
We have not independently established the validity of the foregoing assumptions.
Based upon the foregoing and upon such other investigation as we have deemed necessary and subject to the qualifications set forth below, we are of the opinion that:
| 1. | The Common Stock Resale Shares have been duly authorized by the Company and are validly issued, fully paid and non-assessable. |
