Cryptocurrencies have become an asset class that makes sense in an increasingly digital world. I encourage you to approve this ETF, and other crypto ETFs aimed at investors of more modest means. Ordinary Americans who don't feel tech-savvy enough to buy crypto assets directly deserve a familiar way to add these technologies to their portfolios.

Thank you,
