I can say 100% that 60% of all bounty is a Scam. The reward for them is either given and the tokens will lie on your wallet forever or do not give at all. Then what's the point of doing this ?
Are you complaining or what? If you afraid to get scammed from shit ICOs, don't join or just join when they have escrowed the bounty or you can just join on bounty which use bitcoin as payment
