       Notes to Condensed Consolidated Financial Statements
       Note 4 - Revenue From Contracts With Customers, page 11

   1.                                                   As it relates to your 
pool operator activities, we note your statement that,    The Company   s
                                                        ongoing major or 
central operation is to provide bitcoin transaction verification services to
                                                        the bitcoin network     
  Please revise to indicate, if true, that you also provide these
                                                        services to the 
transaction requestor, in addition to the bitcoin network.
   2.                                                   As it relates to your 
pool participant activities, we note that your reference to       to
                                                        provide computing power 
      is too general to distinguish whether you provide a good or
                                                        service and too general 
to describe the nature of such good or service. Please revise to
                                                        clarify, if true, that 
as a pool participant in mining pools not operated by you that you
                                                        provide a service of 
performing hash calculations for pool operators.

3.       Your statement that    The Company currently mines in a self-operated 
pool    appears to be
         inconsistent with your disclosure that a pool in which nonconsolidated 
entities participate
         does not exist subsequent to May 2022 and, for the period from 
September 2021 to May
         2022, appears to conflate your pool participation activities and your 
pool operator
         activities. That is, as it relates to the activities of what you call  
  a self-operated pool    for
         all periods, including from September 2021 to May 2022 when 
nonconsolidated entities
         participated in your mining pool, it appears that your consolidated 
financial statements
         would depict you providing a transaction verification service, not a 
service of providing
         hash calculations. Please tell us if our understanding is correct. If 
our understanding is
         correct, reconsider the use of this phrase or make appropriate 
clarifying revision.
4.       Revise the table so that    Operator - block reward    revenue is not 
characterized as revenue
         from contracts with customers. Refer to ASC 606-10-50-4.
5.       We note your disclosures related to your Operator revenue policy 
indicating that a
         contract is deemed to exist at the point in time that the performance 
obligation is satisfied.
         Please further revise your disclosure to include your assertions that, 
if true:

                the transaction requestor and the bitcoin network each have a 
unilateral enforceable
              right to terminate their respective contracts at any time without 
penalty;

                for each of these respective contracts, contract inception and 
completion occur
              simultaneously upon block validation; that is, the contract 
begins upon, and the
              duration of the contract does not extend beyond, the validation 
of an individual
              blockchain transaction; and

                each respective contract contains a single performance 
obligation to perform a
              transaction validation service and that this performance 
obligation is satisfied at the
              point-in-time when a block is successfully mined.
6.       Revise your Operator revenue policy to clarify, if true, that the 
transaction price is fixed as
         of the inception of each individual contract, contract inception 
occurs at the same point in
         time you validate a block, and that you measure such noncash 
consideration at the point in
         time the Company successfully validates a block, which is contract 
inception.
7.       Consider clarifying the statement within the first sentence of the 
Participant revenue
         policy that references    only when the Company-operated mining pool 
is not available.   
         We note this statement appears to be referring to the Company   s 
business practice, rather
         than describing its accounting policy; however, as it relates to 
business practice, it is not
         clear what    not available    means and the frequency of this 
occurrence. We also note that a
         Company-operated pool does not exist after May 2022.
8.       For your Participant revenue policy, we note the revised description 
of your performance
         obligation in response to prior comment 4. As previously requested, 
please further revise
         your disclosures throughout the policy to consistently describe the 
nature of your
         performance obligation. That is, revise references to computing power 
or hash rate to

FirstName LastName
         more accurately describe the performance obligation as a service to 
perform hash
         calculations for the pool operator. Please make similar revision to 
references in your Pool
         Operator policy in which you state that you engaged unrelated 
third-party mining
         enterprises (   pool participants   ) to    contribute computing power 
   and to    contribute their
         hash rate.    In addition, in the 5th paragraph of your Participant 
revenue policy, please
         reconsider the appropriateness of referring to this as the    primary  
  output of your ordinary
         activities, considering you also generate revenue as a pool operator.
9.       In your Participant revenue policy, as previously requested, please 
revise to provide a
         more precise description of the payout formulas and identify the 
formula inputs that create
         variability for each component of the payout formula (i.e., block 
reward, transaction fee,
         and pool fee rate). Also, please describe the measurement period for 
the underlying
         variables used to calculate the payout (e.g., for the 24-hour period 
beginning at midnight
         UTC daily). Also, ensure your disclosure articulates the difference 
between PPS and FPPS
         payout methodologies. For example, revise to clarify that, under FPPS, 
transaction fees
         are also earned in addition to the block reward. In addition, in your 
description of rewards
         paid only when the pool successfully mines a block, replace your 
references to computing
         power in describing your fractional share with more precise terms.
10.      Please refer to the second paragraph in your Participant revenue 
policy and revise your
         disclosure to address the following:

                Clarify, if true, that contract inception occurs once your 
performance of hash
              calculations commences. That is, clarify, if true, that your 
enforceable right to
              compensation only begins when you commence providing hash 
calculation services
              for the mining pool operator;

                Revise the sentence that starts with    These contracts are 
period-to-period
              contracts       to be more precise. Similarly, remove the example 
that refers to second,
              minute or hour. For example, disclose your assertion that each 
party has the unilateral
              right to terminate the contract at any time without any 
compensation to the other
              party for such termination and, if true, that as a result the 
contract is continuously
              renewed many times throughout the day, such that the duration of 
each contract is
              less than daily; and

                Clarify the statement indicating the implied renewal option is 
not a material right.
              More specifically, is it correct that        there are no upfront 
or incremental fees in the
              initial contract       and       the terms, conditions, and 
compensation amounts for the
              renewal options are at the then market rates   ?
11.      In your Participant revenue policy, we note your disclosure that, for 
PPS and FPPS
         contracts, you measure revenue based on the average daily spot rate of 
bitcoin. Please tell
         us and clarify in your disclosure whether this is a simple average and 
whether the average
         is computed using spot prices on the date of contract inception. Also, 
consider replacing
         the reference to measuring    revenue earned    with    noncash 
consideration    to better
 Salman Khan

         distinguish your policy for measurement pursuant to Step 3 of ASC 606 
from recognition
         pursuant to Step 5 of ASC 606.
12.      We note that for third-party mining pools in which you participate 
that pay rewards only
         when the pool successfully mines a block that you measure noncash 
consideration using
         the spot rate of bitcoin at the time that the block is successfully 
mined. We note that this
         does not comply with the requirement in ASC 606-10-32-21 to measure 
noncash
         consideration at contract inception and is inconsistent with the 
method you use to measure
         noncash consideration in your other mine pool participant contracts 
for which you
         measure noncash consideration based on the average daily spot rate of 
bitcoin on the date
         of contract inception. Please revise to select an accounting policy 
that uses the same
         measurement approach for each date, consistently applied for all types 
of participant
         contracts, to measure the fair value of noncash consideration on the 
date of contract
         inception. Please provide us with your materiality analysis of the 
impact of this correction
         on each of the financial statement periods presented.
13.      Please revise your Participant revenue policy to clarify for each 
payout method whether
         variable consideration is constrained and to reference in your 
disclosure the threshold for
         application of the constraint articulated in ASC 606-10-32-11. If 
variable consideration is
         constrained, clarify in your disclosure whether the uncertainties 
underlying the constraint
         are resolved on the date of contract inception.
14.      In your Participant revenue policy, please revise to disclose when 
revenue is recognized
         and how that relates to the date on which control of the contracted 
service transfers and
         the date of contract inception. For example, if non-cash consideration 
is recognized on the
         same day that control of the contracted service transfers to the 
mining pool operator and
         that is the same day as contract inception, revise your disclosure to 
state this.
