Ico is really profitable, but the premise is that after the project is invested, it can definitely get rich rewards. If not, please don't invest. In my opinion, almost 80% of the projects in the market are deceptive.
Do not be deceive of the promise of the ICO that you can get a big profit, there are a lot of ICO's that looks like good and is promising but in the middle will just stop and end up to be a scam, so do not be a victim, always be smart in choosing a good ICO.
