Dear SEC, I write to you as a GBTC shareholder, in support of
 the conversion of Grayscale Bitcoin Trust (OTCQX: GBTC) %2�� the world%2��s largest publicly-traded cryptocurrency fund %2�� to an ETF. By not approving this conversion, you are not protecting me, the investor %2�� 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%2��from which both vehicles derive their prices%2��we,
 as investors, should be able to choose if we%2��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 am 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, ***MARY ANNE DOLAN***
