                                                        it appears that the
principal market to measure fair value of your Bitcoin was Coin Metrics

Summary, page 3

2.       We note the disclosure that the purpose of the Trust is to provide
investors a cost-effective
         and convenient way to invest in Bitcoin. Please revise to clarify that
an indirect
         investment in Bitcoin through your Units may operate and perform
differently from a
         direct investment in Bitcoin and to summarize the material
differences.
3.       We note the statement that there can be no guarantee that you will be
successful in listing
         the Units on a national securities exchange and that any such listing
will require the
         national securities exchange to first receive approval from the SEC.
Revise to
         additionally state that to date no national securities exchange has
received such approval
         for any Bitcoin trust. In addition, correct the erroneous cross
reference to    There is no
         guarantee that an active trading market for the Units will continue to
develop.
4.       Please disclose in the summary that the Trust is passive and not
actively managed, as you
         state on page 42.
5.       We note the statement on pages 4 and 5 that "The Trust currently
expects that the value of
         any such Additional Currency would be determined by reference to the
principal market."
         Please disclose what discretion the Trust has in this regard.
6.       Please define Actual Exchange Rate on page 5.
7.       We note the disclosure here that the Trust   s investment objective is
for the Units (based on
         Bitcoin per Unit) to reflect the value of the Bitcoins held by the
Trust, determined by
         reference to the Index, less the Trust   s expenses and other
liabilities. Please explain how
         the Trust evaluates its ability to meet the investment objective in
light of the fact that there
         is currently no secondary trading market or redemption program for the
Shares.
Valuation of Bitcoin and Bitcoin Holdings, page 3

8.       We note you disclose that the Bitcoin Market Price is calculated using
a non-GAAP
         methodology. We also note your disclosure on page 2 that appears to
indicate that the
         Bitcoin Market Price is used to measure fair value under US GAAP.
Please revise to
         more clearly explain the differences between the fair value
measurements used for US
         GAAP amounts and for non-GAAP financial measures. To the extent you
have non-
         GAAP financial measures, please revise to disclose the information
required by Item 10(e)
         of Regulation S-K. Additionally, please revise to ensure your
disclosure throughout the
         filing clearly distinguishes if a fair value metric is GAAP or
non-GAAP measure.

Risk Factors, page 7

10.      Provide separately-captioned risk factors addressing the following:
             The lack of insurance protection for the Bitcoin that you hold and
             Because the Units reflect the estimated accrued but unpaid
expenses of the Trust, the
             number of Bitcoins represented by a Unit will gradually decrease
over time as the
             Trust   s Bitcoins are used to pay the Trust   s expenses.
The value of the Units relates directly to the value of Bitcoins, the value of
which may be highly
volatile and subject to fluctuations..., page 15

11.      Please revise this risk factor to provide quantitative information
regarding the volatility of
         the price of Bitcoin generally and in recent periods, including the

Due to the unregulated nature and lack of transparency surrounding the
operations of Bitcoin
exchanges..., page 17

12.      You state that Bitcoin exchanges are relatively new and, in some
cases, unregulated.
         Please revise to discuss in greater detail the extent to which the
material aspects of the
         business and operations of Bitcoin exchanges are not regulated. For
example, please
         address the fact that trading platforms for digital assets do not
appear to be subject to
         regulation in a similar manner as other regulated trading platforms,
such as national
         securities exchanges or designated contract markets.
Difficulties or limitations in the processes of issuance and redemption (if
any) of Units may
interfere with opportunities for arbitrage, page 19

13.      Provide here a quantitative discussion of the historical premiums of
the closing price of
         the Units quoted on OTCQX (and OTC Markets) over the value of the
Trust   s NAV per
         Unit.
Disruptions at Bitcoin exchanges and potential consequences of a Bitcoin
exchange's failure...,

15.      Revise here and in the Description of the Custodial Services Agreement

             Explain what is meant by the statement that the Trust must use the
Custodian   s
             service on an    as is    basis;
             Explain more fully what is meant by the statement that the

Sponsor will employ

should one or more
         specific rule(s) fail. You also disclose that if the Sponsor makes a
good faith
         determination that each sequential rule does not reflect an accurate
Bitcoin price, it will
         employ the next rule to determine the Bitcoin Market Price. Please
revise to disclose
         any criteria that the Sponsor would use in making such determination.
To the extent such
         determination will not be based on predefined criteria, state so here,
and add a risk factor

on page 38.

paid-in capital should
         represent the accumulated investment in the trust as of each period
end presented.
         Similarly, you should present the accumulated amount of the unrealized
appreciation on
         investment in Bitcoin as of the period end as opposed to the net
