Dear Committee,

I'm writing you today to please approve the bitcoin ETF requests. I believe without an ETF, retail investors are currently required to take great risk when investing in bitcoin through unregulated channels. An ETF would work to help protect retail investors and give wider access to a blossoming asset class that people want to invest in a regulated, safe, and transparent manner.

Thanks for taking the time to read my note.

Cheers,
Sam
