i have a question for you which may help answer your question here also.
you don't have to actually answer it but it is a good thing to think about a little.
from all these ICOs that you mentioned in different fields that have already happened, some of which a long time ago, which one of them do you know that actually did something after a while, like a couple of months, after their ICO ended?
did everything end after the ICO fund raising or did they do something in the world with the money they received? where are the results?
