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.
