Actually I also find it difficult to determine which ICO is good and bad. Also how to choose a productive project and a scam. But I have been able to direct from a successful and successful bounty master by following various ICO's, that how to determine good, productive and not scam ICO is to look at the structure of the ICO teams that we will follow, at least we ask some of its team ( personally via chat) is it true he became the ICO team and asked about the others.
