Hello,

I want to express my enthusiasm for a Bitcoin ETF. As an investor, I see the incredible potential of technology like Bitcoin, and I am of the opinion that all US citizens should have the ability to invest safely through an exchange traded fund. This would allow a broader investor base to enter the market, thereby increasing liquidity and stabilizing prices.
