The country where the ICO comes from is the least of your concern if you're going to determine if it is a scam or not because look, If a project from whatever country succeeded it doesn't mean that the next one whoose also from that country will also succeed . If you're talking about if the next project will inherit some reputation, maybe yes but its not that noticeable I think? cause I believe the community judges a certain project based on its concept, devs, connection, upcoming projs etc. . It doesn't really matter which country/race it comes from .
