I support the regulatory approval of Bitcoin (and other major cryptocurrencies) ETFs. The blockchain technology that underlies Bitcoin is likely to be the driver of the world's next great technological revolution (previously computers, then the internet). The USA should take the lead in promoting innovation in this area to ensure that our economy continues to be the leader in technological improvement. Our regulators in the SEC can help in this goal by approving Bitcoin ETFs and other reasonable means for investment in this space.
