ICO will never die, thats the best way to introduce project to the world although as Facebook, Google and some other big fishes of internet banned the advertisement for Crypto Currencies this doesnt means ICO will die but, of course the manner of doing ICOs will be altered.
Comparing to the beginning of this year, fundraising using ICOs decreased by 5 times. The reason for this is the presence of scammers, hacks, and mistrust of crypto. Moreover, ICOs may disappear completely because of these. Blockchain and other technologies have to be reliable and ICOs are without scammers.
