Everything seems to indicate that the market is mortally wounded, and the main cryptocurrency that had served as a means of payment for those who participate in bounties (ethereum), has lost the confidence of investors and developers who are looking for new alternatives to face the lack of capital willing to take risks in this market. Therefore, it is likely that the bounty hunters will have to settle for peanuts as of this year.
And now, when after three or six months of participating in campaigns you are compensated with tokens without any value and you realize that this business is dead, what are you going to do, bounty hunter?
The way you phrase your post makes it seem as if most bounty hunters are depending on the income that they get out of those campaigns to sustain themselves, and if that is the case, then they are completely responsible of depending in something that was so volatile, however I think you are exaggerating, ethereum is not mortally wounded and it will recover but it will take some time.
