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. 
As an owner of GBTC, I strongly feel such conversion is warranted in order to level the playing field 
Sincerely, 
H Clare Moster
