I think it's not as bad as you think. Yes, there are many scams in the ICO, but they become smaller every day thanks to the joint actions of the community to regulate this industry. IMHO
Of course, investors and all those who care about crypto, I think, have anticipated and appealed to the many ico crimes lately. I think investors and others have been able to overcome and can be more careful in choosing a good ico. those who are not careful can be fooled by fake ico and accept losses.
