Dear Commissioners Piowar and Stein,

Thank you for allowing public comment on this subject. I feel strongly that a bitcoin ETF should be approved. The United States has long been a country that thrives because we embrace innovation. Just as the Internet paved the way to massively building the economy and creating millions of jobs, blockchain technology offer similar promise. This opportunity should be embraced, not rejected.

Regardless of approval or rejection, investors will continue to make investments in bitcoin and blockchain technologies. However, rejecting the ETF will only create a more risky environment for the investor as they will not have the option of investing through regulated exchanges. If your intention is to protect the investor, the bitcoin ETF should be approved to allow investors a vehicle that is regulated.
