It is not easy for Bounty managers to predict scam. It is better to talk to Bounty manager ad make a solution by which you can contact team of ICO , if it is scam then take help of bounty manager and raise voice against ICO team.
Yea, it doesnt mean bounty manager knew about scam. I remember one ICO, which was going okey and then manager made an announcement that he has some predictions it could be scam and then he was sure it was. So he really saved our time and I was very thankful to him. So there is no need for manager to hide the truth.
