The problem with your rant is that it can come across as it the problem is you, and that you're just picking bad projects. I give you the benefit of the doubt though.
I think it's just bed to find a real life job and invest part of your earnings.
The thing is, in an ICO everything is potential and may go either way. There are also promising ICO that had been successful in their campaign but failed to pay the bounty participant. One of them I think is Tokenpay. You will feel how OP feels when you do bounty here. It is quite funny how you tell something to OP when you yourself had not experience this stuff. Though I agree that it is best have a real life job.
Actually I'm not criticizing the OP at all. I'm basically saying that his problems might be legit, definitely legit for him, but that many people won't really sympathize because they will just see it as though he's just not good at what he does.
