Hello, my name is Robert Eisdorfer and I just want to express my highest support for the CBOE Bitcoin ETF. It is my hope that you will approve the ETF. I think it would be very good for the overall progress of this technology that will revolutionize our world. This would allow much easier access for anyone to be able to have a stake this advanced technology. Thank you for your consideration and best wishes.
