Hi,
I am writing to the sec in regards to a bitcoin etf. I believe this should happen. One reason is that the public which you serve is requesting it. Also whether or not you think bitcoin is a legit asset, you should still let the public determine that. If something is going to fail or succeed it will do it whether you proceed on or withhold opportunities. However, you look like a true governing body looking out for the best of the public by letting the market naturally determine its worth.
Thanks for your time
