Hello there,

I just wanted to comment on the cryptocurrency / bitcoin ETF. I think there is a huge need for legitimizing cryptocurrency and needs of the retail investor of the security and tax advantages that ETFs provide.

Right now to invest in cryptocurrency or bitcoin, i need to purchase on an exchange, which is prone to hacks or scams. I need to keep my own bitcoin, which could be lost by me or taken by force.

Additionally, I cannot invest my 401k or IRA's in bitcoin or cryptocurrency, meaning there are no tax efficient ways to invest in a promising and exciting new field.

I hope that this ETF gets passed for the sake and safety of my family and other small retail investors.

Thank you for your time,
- Keith Larson
