Dear SEC, 
I write to you as a GBTC and ETHE shareholder, in support of the conversion of Grayscale Bitcoin Trust (OTCQX: GBTC) and Grayscale Etherium Trust. — 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. Personally for me it is in excess of $100,000. I would like for you to convert to an ETF.
I’m writing from Washington State, 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, 
Tim Caudill
GBTC ETHE share holder
