a successful ICO is not a project that gets pumped more, or not a project that can scam more number of people to raise the most amount of money from those whom they scammed!!!
a successful ICO is a project that actually delivers something, a product or a service that they promised to deliver when they were raising all those money and were happy about it.
so far more than 2 years has passed from the hype of ICOs and not a single one has actually delivered anything.
I think that is true, there are a lot of ICOs that reach hardcaps but are very slow in developing their platforms.
