3.     The disclosure on pages 20-21 briefly describes why you do not believe
that BTCS, Inc.
       is an investment company under the Investment Company Act of 1940.
Please provide
       further information needed to conduct an analysis under sections
3(a)(1)(A) and
       3(a)(1)(C) of the 1940 Act and any other provision of the 1940 Act upon
which BTCS,
       Inc. is relying to exclude it from the definition of an investment
company. In particular,
       list all assets held by BTCS, Inc. and the value you assign to each on
an unconsolidated
       basis. Ensure that your analysis also addresses your plans to
participate in initial coin
       offerings.

Risk Factors

Digital ...," page 6

4.     Rather than referring to "Digital Assets" generally, revise your risk
factor disclosure to
       distinguish between the types of assets you are referring to and any
uncertainties specific
       to that category of currency.

Risks Related to the Bitcoin Network and Bitcoins, page 10

5.     In light of your stated intent to invest in digital tokens and
participate in initial coin
       offerings, expand your risk factors to address the specific risks

       holding these types of assets. Expand to discuss with specificity the
impact on your
       business if your assets are deemed to be securities for the purposes of
federal securities
       laws. Further, to the extent that your proposed merger with Blockchain
Global Limited
       raises any other regulatory obligations under the federal securities
laws, ensure that you
       discuss any resulting material risks to your business.

6.     In light of your stated intent to invest in assets other than bitcoins,
expand your disclosure
       to describe the nature and characteristics of these assets. Although
your discussion
       addresses the implications related to the possibility of bitcoins being
deemed securities,
       expand to address the various types of digital currencies and assets
that you intend to
       hold, which you state includes protocol tokens. Revise your disclosure
under
       Government Oversight on page 42 to address the regulatory treatment of
these assets.
