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 ?
I am taking my chance with that 40%, but always increase the chance by choosing and selecting a good bounty, not by joining all bounty
Become a bounty hunter is means you're facing the same risk as trading or investing. You'll never know what will happen next. But the difference is we do it with less (and almost none) of our money than the investors did. There's no guarantee that the project you've participated in will be successful (even for the so-called "good project") or vice versa. Take the job along with the risk or do nothing and you got empty-handed, it's that simple.
