   1.                                                   In an appropriate place
in this section please provide a concise summary and table of the
                                                        use of funds in this
transaction, to include payments expected to be made to Bitfury and to
                                                        affiliates of the
Company.
       Our success will be highly dependent upon maintaining a successful
relationship with Bitfury...,

   2.                                                   Explain how your
agreement with Bitfury to deliver critical equipment will be maintained
                                                        "on an arm's length
basis" in light of Bitfury's control of Cipher.

Risk Factors
We are exposed to risks related to disruptions in the global supply chain...,
page 47

3.       Please revise this risk factor to include a discussion regarding
limitations of and
         competition in microchip manufacturing, including the current shortage
in supply.
Risks Related to Cryptocurrency Mining, page 64

4.       Discuss how the limited supply of bitcoins that can be mined (and the
current mining
         total) affects your business plan.
Background to the Business Combination, page 112

5.       We note your disclosure that Tyler Page worked on a contract basis for
Bitfury
         immediately prior to being designated to be CEO of Cipher. We further
note your
         disclosure on page 181 that Mr. Page served as Bitfury's Head of
Business Development
         for digital asset infrastructure. Please provide a more detailed
discussion regarding Mr.
         Page's duties while at Bitfury. As part of your disclosure, discuss
         management's determination that Mr. Page, the CEO of a Bitfury
affiliate, and former
         employee of Bitfury, could make decisions independently of Bitfury and
conduct
         negotiations on an arms-length basis.
6.       Define the phrase "greenfield company."
The GWAC Board's Reasons for the Business Combination, page 115

7.       In light of the pre-existing relationships between members of the
company's management
         and Bitfury, explain how the board determined that the company's
policies did not trigger
         the need to obtain a fairness opinion for the transaction.
Certain Cipher Projected Financial Information, page 119

8.     We note the assumptions used in preparing your projections through 2025.
Please clarify
       the following:
           The basis for the 100% linear growth in Bitcoin over the five year
period;
           How you determined that the network hashrate will be ~455 Eh/s at
the end of
            2025. In that regard, we note that over the last 4 years the
Bitcoin hashrate has
            increased by a substantially greater degree than your projections
for hashrate over the
            next 4 years;

            Whether you assumed    increases in ASIC efficiency in TH per watt,
and, if so, what

9.       Please revise to clarify whether Bitfury is the manufacturer and
fabricator of the ASIC
         Chips, or whether those chips are sourced from third-party
manufacturers. If so, provide
         disclosure regarding any agreements Cipher or Bitfury has with those
manufacturers, and
         provide the material terms of the agreement. If Bitfury fabricates and
manufacturers the
         ASIC chips, provide a discussion regarding the potential supply
         constraints and manufacturing capacity of Bitfury.
Information About Cipher, page 164

10.      We note your disclosure here and in the summary that you are a
"technological leader in
         the Bitcoin space". Please revise to provide your basis for this
assertion
         including whether it is based on objective factors such as market
penetration or revenue,
         or if it is a belief of management.
Our Key Strengths, page 166

11.      We note that your graph comparing the price of Bitcoin to the hashrate
only reflects
         January 2020 through February 2021. However, you provide projections
and assumptions
         regarding hashrate and price through 2025. Please revise the graph to
reflect a similar
         period of time as your projections to provide greater understanding of
your projections
         and assumptions.
12.      You indicate that your expected average cost of energy of 2.7c/kWh
will provide you with
         a cost leadership advantage over your main competitors and that you
may be able to gain
         market share if the Bitcoin price drops because of your low cost
electricity. Please revise
         to quantify how Bitfury's electricity costs compare to the electricity
costs of its main
         competitors.
13.      We note your disclosure that you may have the ability to mine over
21,000 Bitcoin per
         annum in December 2025. Please revise to clarify whether this is pre-
or post- halving,
         which is expected to occur in 2024. In addition, provide balancing
disclosure regarding
         the limitations on the underlying assumptions in determining that you
will be able to mine
         21,000 Bitcoin per annum.
Unique access to technology for best-in-class performance, page 166

14.      We note your disclosure that New Cipher will benefit from
"most-favored
         nation pricing." Please revise to disclose how Bitfury's Bitcoin ASIC
miners will be
         allocated between New Cipher's operations and Bitfury's existing
mining operations and
         any potential conflict of interest. In addition, disclose the material
terms of the Master
         Services and Supply Agreement, including whether Bitfury must provide
a minimum
         number of ASIC miners, the model and efficiency of the ASIC models to
be
         provided, the time frame for deliver of the ASIC miners, and whether
New Cipher has any
         minimum purchase or payment obligations.

15.      Please tell us whether the Master Services and Supply Agreement
requires that the supply,
         maintenance, and/or operation of the ASIC miners is exclusive to
Bitfury ASIC Miners
         and products. In that regard, we note there are several substantially
larger ASIC
         manufacturers, including Bitmain and Canaan, that may produce more
efficient ASIC
         Chips and miners.
Expected Revenue Structure, page 171

16.      We note that you expect your revenue to consist of Bitcoin block
rewards and transaction
         fees. However, Bitcoin transaction fees are both variable and are
included in the block
         rewards. Please tell us why you have disaggregated transaction fees
from block rewards,
         and provide a discussion regarding the variability in transaction
fees, including the current
         and past average transaction fees per block. In addition, please
expand your disclosure
         regarding your expectation that transaction fees will become a larger
proportion of
         revenue, your assumptions in that regard and by what proportion you
expect transaction
         fees to increase over time.
17.      Address how you will determine when to sell Bitcoin for fiat currency
to fund operations
         or growth and through what exchange. To the extent you have an
agreement with a third-
         party exchange, please disclose the material terms and file the
agreement as an exhibit.
          Discuss whether your Bitcoin will be held in digital wallets,
exchanges or hardware
         wallet, and the security precautions you will take to keep the mined
Bitcoin secure.
Bitcoin Mining, page 176

18.      Please discuss how the company will utilize mining pools and how
mining pools operate.
         As part of your discussion, explain whether the company will aggregate
the hashing
         power into pools hosted by third-parties, the company or Bitfury, and
the fees that will be
         incurred.
Cipher's Management's Discussion and Analysis of Financial Condition and
Results of
Operations, page 178

19.      Refer to your disclosure of Expected Revenue Structure on page 171. We
note that
         you expect to derive revenues from block rewards and transaction fees
earned for
         verifying transactions in support of the blockchain and that a trend
in which transaction
         fees will constitute an increasing portion of revenues as the total
number of Bitcoin
         available to mine declines over time. Please expand MD&A to include a
discussion of
         this trend in known trends or future events, integrating your
discussion with the industry
         information discussed on pages 175 and 176.

20.      We note in Risk Factor disclosure on page 34 that Cipher's success
will be highly
         dependent upon maintaining a successful relationship with Bitfury
Holding B.V. and upon
         the ongoing provision of equipment and services by Bitfury. We note
