The bloom of ICOs has come to an end and it is nearly dead. You may be optimistic to it but just like what majority are saying who can see an actual end to it is about to come. But, if that ICO has really something to offer and it will be useful and usable to their own service then it might be something else. Real world usage or use case is something what people are looking now.
ICO will not die. It will be reorganized. Instead of ICO, we will see the rise of Security Token Offerings backed by the official shares of startups.
We cant have it forever that's the reality if it won't die but it will be reorganized still there are people that will be skeptic to it after the number of ICOs that failed. The same thing can happen if there will be nothing done and possible that it will be crowded as well like this ICO era.
