Dear Mr. Fields: 

I appreciate the opportunity to comment on the proposed rule change.

If the SEC's main purpose is to protect investors, and if billions of dollars are being invested in bitcoin and blockchain-related enterprises, then the SEC should ensure bitcoin investment is, 1) more accessible to a much wider swath of investors, and 2) accessible through an SEC-supervised fund.  

Additionally, considering investors' growing interest in bitcoin and related assets, a regulated financial product is increasingly necessary and serves to limit investors' risk (via regulation and options) and increase the quality and quantity of information available to them.

I believe that innovation is key to America's leadership and economic growth, and the Winklevoss Bitcoin Trust is yet another milestone in our country's history of setting the bar for global innovation.

I encourage the SEC to approve the proposed rule change.

Thank you again for the opportunity to comment.
