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 strongly feel Futures and Derivatives trading is net-harmful to commodities markets, and there is a rising sense of concern as they are advocated over holding physical commodities. 


The United States has been lagging behind the rest of the world in listening to the people that they intend to protect. 


I have been adding value to this country for three decades working in Chemical Engineering, and am becoming increasingly concerned with SEC decisions to do not appear to support us in return. 


I am also an Accredited Investor and do not need additional protection. I would appreciate liquidity in GBTC that enables the fund price to track the market. Grayscale has proven themselves within this space and deserve prompt approval. 



Sincerely, 

Glenn Fuller
