Dear SEC, I am writing to support the conversion of Grayscale Bitcoin Trust (Symbol: GBTC), currently the worlds largest Bitcoin fund, to the first Spot Bitcoin ETF in the United States. Please
 approve their spot ETF as this will open the gates to mass adoption which will only help our country. Sincerely, Josh Siferd
