I think the right question must be: ¿How to stop SCAMS from ICO?, a lot of projects are very great and useful and is worth it to invest in some of them Ex: Substratum, I think these ideas does not have to pay the consecuences of anothers' mistakes.
Yes correct because I see increasingly more people cheat so we have to be more selective to choose Nice rather than ico scam. because many people are abusing his authority for personal gain, and taking the right of another person
