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 international investor from the Netherlands, it’s vital for the US to not fall further behind and acknowledge how mature Bitcoin has become.

Sincerely,
Jori Matthijssen
