IMHO ICOs are just getting started same like crypto. May be they will be regulated more or slow down. Maybe will be a hard time and few months good ICO's wills waiting for set dates but they will keep coming.
That's exactly it. Funding rounds are as old as markets are, only the way they are arranged changes. ICOs open up a lot more chances for smaller companies and also create access for people of every area, origin or background. So why would they die?
