The word "bounty" means getting paid for capturing or retrieving something right? There is no much difference with bounty hunting on this forum too, the meaning of bounty shows that you can't always catch things right, there will be times when failure will occur but some people wants reward for every single projects they promote, even if you are a pro bounty hunter who's very smart at choosing projects you won't always make the right choice.
I agree with you. A Hunter participate in many bounties at the same time. Some of these projects fail and some are successful and raise a good fund. It is normal that payment will not be received from those who are failing. But hunters can expect payment from a successful project. Most hunters are restless in nature. But I think smart hunters understand the situation.
