To whom it may concern,

I got involved in Bitcoin just over 1 year ago. I am completely behind the technology and this only makes sense moving forward. I have found a mechanism to store some wealth and have definitely enjoyed some amazing returns over this time (and yes I paid taxes on my gains). However, I have friends who are interested, but find the complexity (especially when reporting tax gains) overwhelming. I believe that offering ETF's will expand this market to those who are not as tech savvy.

Please approve this ETF to provide exposure to additional people who are waiting for simpler ways to invest.

Thank you,

Mark Zellers
