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.
start acting like a real bounty hunter, if projects don't work out then move on because it's bounty hunting
It's true what you say but i think that your advice is not as easy to follow in reality as it sounds now. Just look at all those altcoin bounties. The problem there is, that you can't really know in most cases if you have chosen the right bounty to join until the bounty is over, because most altcoins are not even listed yet while the bounty is ongoing. If you are part of a BTC-paying bounty that has weekly pay-outs than of course it is easier and faster to find out if the bounty is good or not. If you don't receive your payment for a week or two than it's time to investigate and if you don't get satisfying answers than it its probably time to look for another bounty.
