Dear SEC,

I am a GBTC shareholder who supports the conversion of Grayscale Bitcoin
Trust (OTCQX: GBTC) — the world’s largest publicly-traded cryptocurrency
fund — to an ETF.

In October 2021, you approved futures-backed Bitcoin ETFs, but continue
to reject applications for spot Bitcoin ETFs. Given that investors use
both vehicles to gain exposure to the same underlying asset,
Bitcoin—from which both vehicles derive their prices—we, as investors,
should be able to choose if we’d like direct or futures-based exposure
to that asset.

Furthermore, the discount to NAV in GBTC has been around 25%, on
average, this year. This means that the price of GBTC is less than the
price of Bitcoin, the asset itself. Given that GBTC has about $30bn in
AUM, shareholders like me are experiencing a destruction of value of
around $7.5 billion.

I’m writing from Maryland, with gratitude for the opportunity to express
my view and with the hope that you will approve this conversion and
protect the interest of investors.

Sincerely,

Patricia Rohan
