Dear SEC,

My name is Paul Sindelar and I'm from Arizona and I am in favor of
approving the Form 19b-4 that NYSE Arca filed with you to convert
Grayscale Bitcoin Trust (OTCQX: GBTC) – the world’s largest publicly
traded crypto asset fund, with approximately $30 billion in AUM,
hundreds of millions in daily trading volume, more than 850,000
investors, holding approximately 3.4% of all Bitcoins outstanding – into
a Bitcoin Spot ETF.

This year, GBTC has traded at an approximately 25% discount to its NAV,
which means the price of GBTC is less than the price of its underlying
assets, Bitcoin. With approximately $30 billion in AUM, that results in
approximately $7.5 billion of trapped value from existing U.S.
investors.  We need this value unlocked.


Sincerely,
Paul Sindelar
