I don't think this series of events signals the end of ICOs. Regulation is inevitable. The strongest ICOs will still find a way to succeed, with or without government regulation.
I agree, it will not be the end of Initial Coin Offerings, the strong projects with substance will always find the way. I also would like to point out that SEC is targeting Token used as a security not currency.
Correct, Initial Coin Offerings strong project will find its way to succeed even if there are some regulations may formally announced. I am hoping for the better regulations that may help to identify the scam ICO or maybe at least lessen the scam ICO.
