your responses to prior comments regarding your revenue

         amount of cumulative revenue recognized will not occur       Please 
revise to clarify that
         the constraint is based on cumulative revenue under the accounting 
contract, rather than
         implying it is based on cumulative revenue earned from a customer.
3.       In the last paragraph on page 17, you indicate that when you provide 
bitcoin transaction
         verification services as the operator and a participant in a private 
pool, it is included as
            Operator    revenue. Please tell us why it is necessary to also 
refer to when you are a
         participant in a private pool considering that the mining pool is 
Company-operated and
         this intercompany activity would be eliminated.
4.       In the last paragraph on page 17, you state that you provide computing 
power to
         collectives of third-party bitcoin miners as a participant. Please 
clarify how you define
         computing power. In this regard, consider revising your accounting 
policy to define the
         performance obligation as a service to perform hash calculations for 
the pool
         operator. Please revise your disclosure to use consistent terms to 
describe this
         performance obligation.
5.       For Operator revenue, please revise to describe the components of the 
consideration
         received. That is, explain the nature of block rewards and 
transactions fees.
6.       For Participant contracts, please revise to provide a more complete 
description of the
         payout formulas by identifying the formula inputs that create 
variability for each type of
         compensation.
7.       For Participant contracts, you indicate that a new contract is 
determined to exist each
         period that neither the Company, nor the pool operator, terminates the 
arrangement.
         Considering that the termination provisions are similar to a renewal 
option, revise to
         disclose, if true, that such renewal option is not a material right 
because either the pricing
         in the renewal periods is the exact same as the pricing in the initial 
contract and there are
         no upfront or incremental fees in the initial contract or the terms, 
conditions, and
         compensation amounts for the renewal options are at then market rates.
