Frustrated bounty hunters getting inspired for such motivation, definitely it's not a bad things. Bounties still profitable i don't think, if you joined 50 campaigns and you have been receiving from only 1 project, how your will consider it's a profitable. Not expecting such too much amount which capable to recover your all efforts.
Joining 50 campaigns and still just 1 project will be the one who will profitable and still you can get profit on it so it is also a good news for us although it is very low the payment but still it is good enough and that's the fact behind it. Earning in a 1 project may seems to be hard enough and very low in terms of payment but still you earned that is the beauty behind the bounties.
then what about the other 49 projects? it's like gambling if you follow a bounty campaign. I do not participate in any bounty campaigns. like a fact that you have said that maybe there is only a 1-10% chance, we get payment from the campaign that we follow. that too isn't much worth selling.
