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 live in North Carolina I am very much in favor of a spot Bitcoin ETF.

As time passes, the “environmental” myth  that Bitcoin mining is harmful becomes more and more debunked. Solar farms, flared natural gas facilities, Bitcoin mining companies’ ability to stabilize the energy grid (preventing a blackout like what happened in Texas last year for example), and geographically advantageous facilities (Arctic mining facilities = no cooling costs for maintaining miner temp) are becoming the norm in the industry.

Sincerely,

Curtis Campbell, PT, DPT, CSCS
