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.

There is no need to hold back a spot version of derivatives price sourced ones. Please overcome this challenge timely.

Sincerely,
Toby R
