        2.  execute for and on behalf of the undersigned any Form 3, Form 4,
            Form 5 and Form 144 (including any amendments, corrections,
            supplements or other changes thereto) in accordance with Section
            16(a) of the Exchange Act, and the rules thereunder, but only to the
            extent each form or schedule relates to the undersigned's beneficial

            its subsidiaries;

        3.  do and perform any and all acts for and on behalf of the undersigned

            corrections, supplements or other changes thereto) and timely file
            the forms or schedules with the SEC and any stock exchange or
            quotation system, self-regulatory association or any other
            authority, and provide a copy as required by law or advisable to
            such persons as the attorney-in-fact deems appropriate; and

        4.  take any other action in connection with the foregoing that, in the
            opinion of the attorney-in-fact, may be of benefit to, in the best
            interest of or legally required of the undersigned, it being
            understood that the documents executed by the attorney-in-fact on
            behalf of the undersigned pursuant to this Power of Attorney shall
            be in the form and shall contain the terms and conditions as the
            attorney-in-fact may approve in the attorney-in-fact's discretion.

The undersigned hereby grants to the attorney-in-fact full power and authority
to do and perform all and every act requisite, necessary or proper to be done in
the exercise of any of the rights and powers herein granted, as fully to all
intents and purposes as the undersigned might or could do if personally present,
with full power of substitution or revocation, hereby ratifying and confirming
all that the attorney-in-fact shall lawfully do or cause to be done by virtue of
this Power of Attorney and the rights and powers granted herein. The undersigned
acknowledges that the attorneys-in-fact, in serving in such capacity at the
request of the undersigned, are not assuming (nor is Stronghold Digital Mining,
Inc. assuming) any of the undersigned's responsibilities to comply with Section
16 of the Exchange Act.

The undersigned agrees that the attorney-in-fact may rely entirely on
information furnished orally or in writing by or at the direction of the
undersigned to the attorney-in-fact. The undersigned also agrees to indemnify
and hold harmless Stronghold Digital Mining, Inc. and the attorney-in-fact
against any losses, claims, damages or liabilities (or actions in these
respects) that arise out of or are based upon any untrue statements or omissions
of necessary facts in the information provided by or at the direction of the
undersigned, or upon the lack of timeliness in the delivery of information by or
at the direction of the undersigned, to the attorney-in fact for purposes of
executing, acknowledging, delivering or filing a Form 3, Form 4, Form 5 or Form
144 (including any amendments, corrections, supplements or other changes
thereto) with respect to the undersigned's holdings of and transactions in
securities issued by Stronghold Digital Mining, Inc., and agrees to reimburse
Stronghold Digital Mining, Inc. and the attorney-in-fact on demand for any legal
or other expenses reasonably incurred in connection with investigating or
defending against any such loss, claim, damage, liability or action.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Form 3, Form 4, Form 5 and Form 144
(including any amendments, corrections, supplements or other changes thereto)
with respect to the undersigned's holdings of and transactions in securities
issued by Stronghold Digital Mining, Inc., unless earlier revoked by the
undersigned in a signed writing delivered to the attorney-in-fact. This Power of
Attorney does not revoke any other power of attorney that the undersigned has
previously granted.

                           [Signature page follows.]


        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
