4.       We note your response to prior comment 11. Further explain how your 
policy of testing
         for impairment on a nightly basis complies with ASC 350. In this 
regard, consistent with
         ASC 350-30-35-19, you indicate that impairment exists when fair value 
is below carrying
         value, and ASC 350-30-35-18 indicates intangible assets should be 
tested for impairment
         at any time events or changes in circumstances indicate that it is 
more likely than not that
         the asset is impaired.
5.       We note your disposition of digital currencies of $80,000. Tell us how 
this is reflected on
         the statement of cash flows. Provide an accounting analysis that 
supports your
         presentation, and explain the basis for any differences in the 
presentation from prior
         periods. Also, please tell us whether you lend your cryptocurrency or 
otherwise purchase
         forward contracts related to cryptocurrency. Tell us and disclose your 
accounting policy
         for such transactions, and cite the supportive accounting literature.
Investment Fund, page F-15

6.       You indicate in response to prior comment 13 that your capital 
contribution to the
         investment fund was made in cash. Please reconcile this to your 
disclosures on page F-11
         indicating that you purchased BTC through an investment fund and on 
page 48 that the
         bitcoin was purchased and placed into the investment fund. In 
addition, please explain the
         disclosures throughout your filing indicating that you hold bitcoin in 
an investment fund,
         expect to purchase additional bitcoin held by the investment fund, and 
may sell this
         bitcoin in future periods to generate cash. Also address your press 
release on January 25,
         2021 stating that you purchased $150 million in bitcoin. In this 
regard, you have
         represented that you own 100% of a limited partnership interest in an 
investment fund and
         that entity invests in and holds bitcoin.
7.       We note your response to prior comment 13. Please provide us with your 
proposed
         revised accounting policy for your investment in the investment fund. 
That is, as

comment 13.
         Please further describe to us the design and purpose of NYDIG Digital 
Assets Fund III,
         LP (   DAF III   ). Include in your response: (1) the basis for why 
you would fund 100% of
         the capital of DAF III, yet not retain any control over how that 
capital is deployed; (2)
         why the General Partner does not receive any economics in performance 
of its duties; (3)
         whether DAF III is designed to take on other investors; and (4) 
whether DAF III is
         designed to hold investments other than bitcoin.

General Partner
         and Investment Manager and describe to us any related party

10.      In order to help us further evaluate your response to prior comment 
13, please clarify
         which entity is the limited partner of the Fund and whether the 
limited partner is a
         consolidated subsidiary of the Company for all periods; clarify to 
whom the Other
         Considerations #5 in your response refers and how its expectation    
to purchase additional
         bitcoin held by the investment fund in future periods    is consistent 
with your accounting
         conclusion; and identify the various parties invested in or involved 
with the Fund and their
         relationships as well as the source of the Fund   s bitcoin.
11.      We note your response to prior comment 13 and continue to evaluate 
your analysis.
         Please provide us with a copy of the DAF III partnership agreement, 
the agreement with
         the Investment Manager, and any other pertinent agreements concerning 
the governance
         of DAF III.
Revenue Recognition, page F-15

12.      You indicate in response to prior comment 14 and in your disclosure on 
page 16 of your
         Form 10-Q for the quarterly period ended March 31, 2022 that you 
recognize revenue
         based on the closing price of BTC on the day of constructive receipt 
of the mining
         reward. We note that constructive receipt of the mining reward can be 
at least two days
         from contract inception. As previously requested, please tell us how 
you comply with
         ASC 606-10-32-21 to 32-24. That is, please provide us with your 
analysis of how you
         comply with the requirement to recognize the estimated fair value of 
the non-cash
         consideration at contract inception. In addition, please clarify the 
statement in your
         disclosure,    The value of the BTC rewards, utilizing the prevailing 
market prices at
         constructive receipt, is not materially different than the value 
recognized.    That is, how is
         there a difference in the value recognized if revenue is recognized 
based on the closing
         price of BTC on the day of constructive receipt.

13.      We note your responses to prior comments 15 and 16 and disclosure on 
page 16 of your
         Form 10-Q for the quarterly period ended March 31, 2022. Please 
distinguish between
         how you recognized revenue as a pool participant and how revenue is 
recognized as the
         pool operator. We may have further comment. Also address the 
following:

                As the pool operator, explain how account for the block reward 
earned and how you
              present the allocation of the block reward to the 3rd party 
miners. Provide us with
              your comprehensive principal versus agent accounting analysis. 
Refer to ASC 606-
              10-55-36 through 55-40; and

                You indicate that    mining revenues are recorded net of any 
pool fee, not gross, with
              an offsetting cost of revenue.    Please clarify this statement 
and differentiate your
              accounting for any pool fees earned as the pool operator with 
third party miners, as
              the pool operator and participant in your own pool, and when you 
participated in third
              party pools. Explain the nature of the amounts that are included 
in the offsetting cost
              of revenue. Tell us what consideration was given to whether the 
pool fee you retain
              relates to activities you must undertake to fulfill your contract 
as the pool operator.
              Also tell us whether the BTC rewarded among pool participants, 
net of the pool fee,
              represents the transaction price; and

                Provide us with your proposed revised revenue recognition 
policy disclosure in
              response to our comments.

Non-GAAP Financial Measures, page 17

17.      We note your revised presentation of non-GAAP measures in response to 
prior comments
         3 and 4. Please address the following:

                Revise to remove the adjustment for changes in the fair market 
value of your
              investment fund from your computation of non-GAAP measures. In 
this regard, we
              note your explanation that the adjustment is due to the 
fundamentally different
              accounting for your self-mined bitcoin and because the amount can 
vary significantly
              from period-to-period. Refer to Question 100.04 of the Compliance 
and Disclosure
              Interpretations on Non-GAAP Financial Measures.

                Revise to remove the adjustment for impairment of digital 
currencies from your
              computation of adjusted EBITDA. As previously noted in prior 
comment 3, we
              believe that adjusting for impairment of mined cryptocurrency 
does not provide
              useful information to investors in light of your strategy to hold 
bitcoin as a long term
              investment and sell bitcoin in future periods as needed to 
generate cash for treasury
              management and other general corporate purposes, in addition to 
the recurring nature
              of this charge.

                As previously requested in prior comment 4, explain the nature 
of the non-GAAP
              adjustment to adjusted EBITDA for amortization of prepaid service 
contracts.
              Explain why you believe that adjusting for this item is useful 
information to investors
              as it appears to represent a normal, recurring, operating 
expense. Refer to Item
              10(e)(1)(i)(C) of Regulation S-K and Question 100.01 of the 
Compliance and
              Disclosure Interpretations on Non-GAAP Financial Measures.

                Revise to present the most directly comparable GAAP financial 
measures to basic
              and diluted adjusted net income per share. Refer to Item 
10(e)(1)(i)(A) and (ii)(E) of
              Regulation S-K and Question 102.10 of the Compliance and 
Disclosure Interpretation
              of Non-GAAP Financial Measures.
Liquidity and Capital Resources, page 21

18.      We note your disclosure here as well as the proposed prospective 
disclosure in response to
         prior comment 7. Further revise to provide quantitative and 
qualitative analysis of the
         underlying reasons for the material changes in net cash used by 
operating activities, as
         previously requested.
