Hello,

Thank you for considering a Bitcoin ETF and for allowing public comments on the application.

I believe strongly that listing a publicly available Bitcoin ETF would be in the interest of investors, the public, and the country. We are at a pivotal point in creating a shift in how the world access and utilizes money. This new technology is limitless and will continue to progress in variety of fields from currency to insurance to healthcare to voting. We need the country and the world to embrace and accept this technology. Many are fearful, many are hesitant. A Bitcoin ETF, governed and overseen by the SEC is the first step to legitimize this space and will provide a stable framework for diversifying portfolios and investments. The advancement and economic growth of this technology depends on your support and governance. I urge you to move this application forward.

Sincerely,

Joe Costa
