Nawadays, the ICOs market was affected by scams, which generates distrust in them. Taking into account these events, Will are there some entities or platform that guarantees that an ICO is reliable to invest?
There is no website or a platform that guarantees the success of an ICO. what I know is there some websites that give ratings of each ICO, but you shouldn't believe ratings as a guarantee for success of an ICO because there were some ICOs failed even they had high ratings. So just do your own research first.
