Not the %99 but there are many scam ICO's.. Personally i worked about 30 scam or unsuccesful project and everyday this number getting high for me. I really make researches before i join to bounty campaigns or ICO's. The high pointed ICO rewievs never helps us, it can be scam too, so we have big problem about it.. :/
