Dear SEC,

I’m writing to support the conversion of Grayscale Bitcoin Trust (Symbol: GBTC), currently the world’s largest Bitcoin fund, to the first Spot Bitcoin ETF in the United States.
I am resident in Florida. And I have been long time investor of GBTC. I am very upset about the discount of the GBTC TO spot Bitcoin price.
Please approve GBTC To become spot bitcoin etf. It will be better investor protection for us.
Sincerely,
Sen zhang
