What's the success of most ICOs? Nothing. Only few ICOs are performs well these days. Some are only after exchange listing and dump on community. They forget their usecase
From 2018 to the present, I have not seen any successful ICO. Yes, there are a few ICOs that are still active, but its price has dropped too many times and it is difficult to recover. ICOs have completely failed in this market
It is best to stay away from ICO projects because it certainly will not be profitable for you, and the waiting time is usually very long, so surely investors will feel very bored. I think now IEO is a new investment trend and has been mentioned a lot for more than a year, so I believe that you can feel secure when participating. However, there are still fraudulent IEO projects in this market, and you need to consider them carefully.
