I don't think it is enough to see a ICO by its website and its member that usually we can found mentioned at the site .
Perosnally I myself not believe in the team that are usually shown in sites Because I seen many times that they used internet photos and use them to show as memeber of Thier ICOs project but in actual they makes face show or team , Thier remain nothing .
I see only the basic concept that why they will get investors and also see toward the factors that how many platforms and which platforms are advertising thier project , if project will be better then surely than ICOs will have some better quality and we should invest them .
