ICO is good but the one who makes it bad is the people who use it to scam people is the problem. Therefore if you are going to join investment thru ICO you should use the power of internet as a tool to define if the ICO is legit or not thru constant review and research. If you are bounty participants you should check who is the campaign manager that if possible you choose the popular managers with high rank and positive reputation because the good manager will check well the ICO if legit or not because their good reputation is at stake.
