1.     We note that depreciation is not included within costs of revenue.
Consistent with SAB
       Topic 11.B, in future filings, please change your description of the
line items for cost of
       revenues to indicate that the amounts are exclusive of depreciation
shown separately
       below.

2.     We acknowledge your response to prior comment 1. Please respond to the
following
       regarding your valuation of bitcoin for purposes of impairment testing
under ASC 350:
 July 10, 2024
Page 2

             You told us that you consider Coinbase to be bitcoin   s principal
market, but you did
           not tell us whether Coinbase is your principal market for bitcoin.
Per ASC 820-10-35-
           6A, you should consider the principal (or most advantageous) market
from the
           perspective of the reporting entity.
             For your impairment analysis for the year ended December 31, 2022,
you told us you
           used the lowest intraday quoted bitcoin price from the bitcoin USD
historical data on
           Yahoo Finance and that this is in accordance with ASC 820-10-35-5A
because
           bitcoin prices derived from Yahoo Finance are widely accessible. We
note that Yahoo
           Finance is not itself a market where bitcoin and other
cryptocurrencies are traded.
           Accordingly, we do not believe that your response provides
sufficient analysis to
           demonstrate how your use of Yahoo Finance to determine the fair
value of your
           bitcoin complies with ASC 820. Please expand your analysis to
include, but not
           necessarily limit it to, identifying your principal market and
demonstrating how you
           comply with ASC 820.
             If you agree that your principal market is not Yahoo Finance,
please provide us with
           your analysis of the quantitative impact of using Yahoo Finance
rather than your
           principal market to value your cryptocurrencies for impairment
purposes for all
           periods presented in your financial statements.

3.     We acknowledge your response to prior comment 2. Please respond to the
following:
           Please represent to us that you will revise your revenue recognition
policy in future
          filings to address the following:
            o Disclose, similar to your response, that you have a single
performance
               obligation.
            o Disclose, if true, that the mining pool operators are your
customers.
            o Disclose, similar to your response to comment 6 in your July 27,
2023 letter that
               the services you provide are an output of your ordinary
activities.
             Your response indicates your only performance obligation is to
supply computing
           power because the mining pool operators perform computations based
on their own
           systems. We understand that you run software from the pool operators
that constructs
           block header candidates and performs hash computations on behalf of
the pool
           operators. If you do perform hash calculations for the pool
operators, tell us whether a
           more accurate description of your promise and single performance
obligation is a
           service to perform hash calculations for the pool operator, and if
so, represent to us
           that you will make corresponding revisions to your accounting policy
and related
           disclosures throughout your filing.
             You told us that you believe, under ASC 606-10-25-1, contract
inception occurs when
           you provide computing power to Foundry or Luxor, which is the
beginning of the 24
           hour period (12:00am UTC time) and the contract duration is 24
hours. However, you
           have also told us that your contracts can be terminated at any time
by either party and
           the duration of the contract does not extend beyond the goods or
services already
           delivered. Given your statements about termination rights and
contract duration not
           extending beyond the goods or services already delivered (i.e., the
last hash
 July 10, 2024
Page 3

           calculation) coupled with the discussion in FASB Revenue Recognition
           Implementation Q&As Question 8 that indicates that customer
cancellation rights can
           be similar to a renewal option, tell us your consideration of
whether the contract
           continuously renews throughout the day and therefore that the
duration of the contract
           is less than 24 hours. To the extent that you agree, represent to us
that you will revise
           your accounting policy disclosure accordingly in future filings.
             Because termination rights are akin to renewal options, tell us
whether the customer   s
           renewal option is a material right and whether the terms,
conditions, and
           compensation amounts of the renewal option are at the then-current
market rates. If
           so, tell us whether you concluded that the customer   s renewal
option is not a material
           right that represents a separate performance obligation. Refer to
ASC 606-10-25-18(j)
           and 606-10-55-42. Also if so, represent to us that you will make
corresponding
           revisions to your accounting policy and related disclosures in
future filings that links
           this conclusion to your determination that you have only one
performance obligation.
             The disclosure in your September 30, 2023 Form 10-Q stated that
you measured your
           noncash consideration on the date earned rather than the date that
control of your
           service transfers to the pool operator. We note that you have
revised your disclosure
           to state that you measure the fair value of the noncash
consideration at contract
           inception. Please address the following:
             o Provide us with an analysis supporting your prior statement that
historically
                 measuring noncash consideration on the date earned is not
materially different
                 from the date of contract inception.
             o Tell us the time you use for determining the estimated fair
value of the bitcoin
                 (e.g., at the beginning or at the end of the date of contract
inception, or using a
                 simple average price throughout that date, etc.) and whether
your timing is
                 consistently applied for all periods presented. Represent to
us that you will make
                 corresponding revisions to your accounting policy and related
disclosures in
                 future filings.
             You previously disclosed that you recognized revenue when the
mining pool operator
           successfully places a block and you receive confirmation of the
consideration you
           will receive. We note that you have revised your disclosure to state
that you recognize
           the noncash consideration on the same day that control is
transferred, which is the
           same day as contract inception. Since it appears that you changed
the timing of when
           you recognize revenue, tell us whether applying the corrected policy
to historical
           periods resulted in a material change to the historical financial
statements presented.

4.     We acknowledge your response to prior comment 4 of our letter dated June
23, 2023. You
       disclose that digital assets are included in current assets due to your
ability to sell bitcoin
       in a highly liquid marketplace and the sale of bitcoin to fund operating
expenses to
       support operations. As noted in your response, the definition of a
current asset in the
 July 10, 2024
Page 4

       FASB Master Glossary refers to a reasonable expectation of realization.
Please revise
       your disclosure in future filings to state, if true, that your bitcoin
holdings are reasonably
       expected to be realized in cash or sold or consumed during the normal
operation cycle of
       your business.
