              After reviewing your response to these comments, we may have 
additional
       comments. Unless we note otherwise, our references to prior comments are

   1.                                                   Clarify the types of 
businesses that are "ancillary" to your bitcoin mining business that
                                                        you may expand into in 
the future.
       Risk Factors, page 12

   2.                                                   Please revise to also 
address any material risk or impact that the current crypto asset
                                                        market disruption may 
have on the use and valuation of your mining rigs. In this regard,
                                                        we note the decrease in 
the cost of bitcoin mining rigs that was driven by the drop in
                                                        bitcoin prices during 
the fourth quarter ended December 31, 2022 resulted in significant
                                                        impairment of your 
mining rigs and the deposits with bitcoin mining equipment

         manufacturers. Also address the risk that bitcoin mining rigs would 
have to be shut down
         for lack of profitability once the price of bitcoin declines below a 
certain amount.
We may have further restrictions on our liquidity due to unique risks which we 
could face in
2023, page 24

3.       We note your response to prior comment 23 regarding various risks due 
to disruptions in
         the crypto asset markets. Please address the termination of your term 
loan and line of
         credit with the now closed Silvergate Bank, which was your primary 
lender. Clarify here
         and in your MD&A section how the lack of access to up to $200 million 
of bank loans and
         credit will impact your operations and liquidity. For example, clarify 
whether the lack of
         a lender and current market conditions will make it difficult to meet 
your funding
         obligations for the Abu Dhabi joint venture or the buildout of your 
mining operations in
         2023. Further, clarify whether you may have difficulty finding another 
lender that will
         offer you similar or favorable terms given the current volatile 
environment in the crypto
         asset markets.
4.       We note that your cash is primarily held at Signature Bridge Bank, NA, 
as overseen by the
         FDIC, since Signature Bank, NA, was closed by New York State banking 
regulators.
         Please address the risk to your cash, acknowledging that your deposits 
are only insured up
         to $250,000 at the bank, however, the federal government will provide 
you access to your
         funds but are not required to do so under current banking laws or in 
the future. Address
         how you will mitigate such risks in the future for bank failure of any 
institution where you
         will hold a material amount of cash assets.

5.       Please explain how you determined that the price of digital assets 
used for purposes of
         assessing impairment is a Level 2 input under ASC 820. Refer to ASC 
820-10-35-37
         through 35-54A. Also explain how the use of    multiple observable 
inputs (exchanges)
         that provide slightly differing benchmarks of digital asset value    
is consistent with the
         guidance in ASC 820-10-35-5.
6.     Please tell us why your policy indicates that any realized gains or 
losses from sales of
       digital assets are included in other income (expense). In this regard, 
we note the
       classification of realized and unrealized gains (losses) on digital 
assets loan receivable and

7.       Please clarify your performance obligation in contracts with mining 
pool operators as a
         participant. You indicate that computing power is the only performance 
obligation, but
         also indicate that providing computing power to solve a block is the 
primary output of
         your ordinary activities.
8.       We note your statement on page 39 that    There is currently no 
definitive guidance under
         GAAP or alternative accounting framework for the accounting for 
digital assets
         recognized as revenue or held,    and your disclosure on page 29 that  
  no official guidance
         has yet been provided by the Financial Accounting Standards Board.    
Please help us
         understand the basis for these statements and consider the need to 
revise or remove this
         disclosure.

9.       You indicate that the impairment tests for items of property and 
equipment other than
         mining rigs are performed annually and the recoverable amounts in 
property equipment
         are determined based on the higher of value-in-use or fair value less 
costs to sell. Tell us
         how your accounting policy complies with ASC 360-10-35-17 and 35-21.
Results of Operations, page 42

10.      We note that you disclose your bitcoin production during the period in 
the supplemental
         information provided in the charts on pages 42 and 45. Tell us what 
consideration you
         gave to also discussing and analyzing additional metrics that are key 
performance
         indicators, such as the average BTC produced per day, 
operational/energized hash rate,
         and installed hash rate, as disclosed in your monthly press releases 
announcing updates to
         your bitcoin production and mining operation. Refer to Item 303(a) of 
Regulation S-K
         and SEC Release No. 33-10751.
11.      In your discussion of the change in cost of revenues, please explain 
how higher production
         costs of $30,134 thousand per bitcoin mined contributed to an increase 
in cost of revenues
         of only $45,226 thousand during the year ended December 31, 2022. In 
this regard, we
         note that bitcoin production increased by 947 BTC in 2022. Tell us if 
$30,134 thousand is
         actually the increase in production costs for the total bitcoin mined 
during the year, rather
         than the increase per bitcoin, and, if so, please revise.
12.      Please revise to describe the underlying reasons for the material 
changes in stock-based
         compensation expense. Refer to Item 303(b) of Regulation S-K.

         impacts of the errors. Considering your assertion that the period 
ended December 31,
         2022 was not subject to restatement, please tell us why your tables 
show the impact for
         that period. In addition, revise to disclose the impact of each of the

19.      We note your disclosure that you measure the fair value of bitcoin 
earned using the daily
         quoted closing U.S. dollar spot rate each day for reasons of 
operational practicality. As
         we continue to evaluate your Operator accounting policy disclosure, 
please further explain
         why it is appropriate to measure noncash consideration other than at 
contract inception in
         accordance with ASC 606-10-32-21. Tell us what consideration you gave 
to measuring
         noncash consideration at the point in time that the block is 
successfully solved.
20.      As we continue to evaluate your Participant accounting policy 
disclosure, please tell us
         and further revise your revenue recognition policy disclosure to 
ensure the following
         items are succinctly articulated, as previously requested in prior 
comment 5:

                Explain the payment terms of your contracts, including how the 
amount of
              compensation paid to you by third-party pool operators is 
determined;

                Clearly disclose what you believe is the duration and inception 
of your contracts. In
              this regard, you disclose that your contracts are    
period-to-period    contracts and a
              new contract is determined to exist    each period    that 
neither party terminates the
              arrangement. Revise to define what you consider to be the    
period.    We note from
              your response to comment 20 in your letter dated December 2, 2022 
and your
              response to prior comment 6 in your letter dated March 10, 2023 
that such period
              reflects a distinct increment of time of a minute. However, you 
also indicate in
              response (d) to prior comment 6 in your letter dated March 10, 
2023 that contract
              inception is upon successful placement of a block on the bitcoin 
blockchain;

                Indicate when you believe that you satisfy your performance 
obligation; and

                Clarify your disclosure of why you believe variable 
consideration is no longer
              constrained upon settlement, consistent with the guidance in ASC 
606-10-32-11 and
              32-12. That is, you indicate this is the point that the    
variability is resolved    and
              there is no longer the    reasonable possibility    of 
significant reversal of revenue and,
              before settlement, the estimation of variable consideration    
carries the risk of    a
              significant revenue reversal. In this regard, variable 
consideration should be
              constrained to the extent that it is probable that a significant 
reversal of revenue will
              occur when the uncertainty related to the variable consideration 
is subsequently
              resolved.
21.      We note your supplemental response to prior comment 6 in your letter 
dated March 10,
         2023 regarding the quantitative impact of your accounting convention 
as a Participant. As
         we continue to evaluate your accounting policy, please also provide us 
with your
         sensitivity analysis of the impact of the difference between 
recognizing revenue at fair
         value of bitcoin at contract inception versus recognizing and 
measuring revenue at the
         daily closing U.S. dollar spot rate of bitcoin on the date of receipt 
of the block rewards
         and transaction fees for the quarterly and annual periods in the year 
ended December 31,
         2021.

22.      As we continue to evaluate your revenue recognition policy as a 
Participant, please clarify
         the basis for measuring noncash consideration using the daily closing 
U.S. dollar spot rate
         of bitcoin on the date of settlement. Although, as indicated in 
response to prior comment
         6 in your letter dated March 10, 2023, you do not have visibility into 
the exact moment of
         contract inception, tell us what consideration you gave to measuring 
noncash
         consideration at the point in time that the third-party mining pool is 
successful in the
         placement of a block on the bitcoin blockchain. Tell us how much 
transaction fees and
         your proportional contribution of computing power to the pool actually 
vary from block to
         block during a single 24-hour period.
23.      In response to comment 20 in your letter dated December 2, 2022, you 
state,    ASC 606-
         10-32-21 requires noncash consideration to be measured at fair value 
at contract inception
         which is at each minute...    However, you state in your response to 
prior comment 6 in
         your letter dated March 10, 2023,    as a participant in a third party 
pool, the company has
         no visibility into the exact time of contract inception and it is 
therefore impossible to fair
         value the revenue recognition at the contact inception.    You also 
indicate that the amount
         of remuneration to which you are entitled is not known at the time a 
block is won as the
         transaction fees per block, and the proportion of the Company   s 
contributed computing
         power to the pool (which have significant effect on the fractional 
share of the block
         reward and transaction fees to which the Company is entitled) are both 
unknown until
         settlement into the Company   s wallet. Tell us what impact, if any, 
your inability to
         measure noncash consideration in accordance with GAAP has on your 
assessment of
         controls and procedures.

24.      In response to prior comment 15, you indicate that the use of the
