The more the SEC cracks down on unregistered securities posing as ICOs ,the more the atmosphere in crypto will change .IMO , ICOs will not die but they will definitely have to take a new form and STOs will play a big role. I believe this is a gods thing for the industry.
I don't think STO will last long and ICO will be victorious again, many of us don't like KYC and that makes STO not much interested in people and there are also some STO rules that must be followed which make many people dislike STO.
