I think it is only the matter of time when bounties are going to recover. If you look at the market between 2016 and 2017, it was almost always raising. There was no such a dramatical fall and people have earned money.
2017 was very good at choosing bounty campaigns. I worked and earned good money. And I almost didn't meet bounty hunters who were unhappy with rewards or projects in general. Therefore, I agree that as soon as the market begins to recover, the bounty campaigns will also become former.
