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 in the state of Massachusetts and am self employed. I would like the ability to hold btc with my IRA





Thank you
Bob
