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. 
Having a futures ETF only is hurting us investors. It’s time for a spot. I hope you’ll consider this.
Sincerely, 
Erick Arndt
