I think we should choose the bounty carefully, there are many bounty in the markets and should be find a good bounty can make profit, this sure depend on the project itself.
But you must agree with the OP that bounty hunting days are long gone! The time and effort you put in finding such a good project is just too much as compared to the end rewards and it's worrisome that we have many shitty bounties still being run and people always sign up hoping it turns out a successful project without doing any research.
