Dear SEC,

I am writing in support of the application to convert GBTC into a spot
ETF...this action would save investors' money.  To me, it seems that bitcoin
as an asset class has matured to the point that this makes prudent sense
especially since bitcoin is capitalized in the hundreds of billions and is a
24/7 market priced on multiple exchanges in multiple jurisdictions worldwide
(and even in outer space!).  In fact, of all the assets I can think of, this
one, being completely voluntary and working with human nature, and being
decentralized, is most likely the most manipulation-proof asset ever created
by humanity!  Please, let's join the ranks of other countries that have
already made this move.

Sincerely,
Steven Adler
Palm Springs, California
