Comment for consideration.

Digital and decentralized currencies specifically Bitcoin are widely accepted to be an important part of our future global financial system. Delaying an ETF for Bitcoin will only result in investors finding alternative, less regulated and more risky vehicles to participate.... I understand the real and serious concerns that the SEC have on this topic but the truth is the crypto train has left the global station and no action or action that stifles US participation is much higher risk then anything else. I encourage the SEC to begin taking pro-active steps for defining and regulating the crypto marketplace which I believe should start with an ETF as well as much stronger oversight and policing of US based exchanges.
