Dear SEC,

I write to you as a GBTC shareholder, in support of the conversion of
Grayscale Bitcoin Trust (OTCQX: GBTC) — the world’s largest
publicly-traded cryptocurrency fund — to an ETF. By not approving this
conversion, you are not protecting me, the investor – the very person
you were appointed to protect.

Last October, 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 Oklahoma City, Ok, 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,
 Tia Cooper
