I strongly support the proposal of Bitcoin ETF.
Blockchain technology should be an area of focus for the government since it has a wide variety of useful applications in the digital era we live in today. Our government should ensure there are safe vehicles for investing in innovative technologies and supporting a Bitcoin ETF will be one step towards regulating and protecting consumers.

Thank you,
Mason Gray
