The Scam ICO actually is very smart when their do a some promotion strategy. Everything they will do It but they not think about influence that already they were have given. Because that, ourself must be elaborate when choosing many project to investation.
For me, the first sign of good ICO is a real team, and most key people from the team can be found in the social.
And team with real people scamming as well. Where's the point? I think a project with 0% premine, and no ICO is the best project. Those are community based project and have the chance of grow bigger.
