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. 


Bitcoin futures ETFs are allowed in the U.S. and many other countries already have Spot Bitcoin ETFs, please don't delay this decision any longer. 

Sincerely, 
Helen Hsiu, California, US Citizen
