Dear SEC, I write to you as a GBTC shareholder, in support of the conversion of Grayscale Bitcoin Trust (OTCQX: GBTC) 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 would like direct or futures-based exposure to that asset. I personally do not see the benefit of the futures based product. 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, existing shareholders like me are experiencing a destruction of value of
 around $7.5 billion. GBTC is the world's largest publicly-traded cryptocurrency fund, with hundreds of millions in daily trading volume. It holds approximately 3.4% of all Bitcoins outstanding, and is held by more than 850,000 investors, like me. I am writing
 from Texas, with gratitude for the opportunity to express my view to you and with the hope and expectation that you will approve this conversion and protect the interest of investors. Sincerely, Terri Flowers
