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 an active investor and businessman in NC and am heavily invested in the local community. Thank you for considering this. 

Sincerely, 

David Sillman 
Managing Member 
Ad Astra Trust
