The bounty hunter's services are paid for with tokens and not with live money, so it is not known in which projects he will at least earn something))
That is why a bounty hunter is more an investor than an employee.
I agree with you. That is why bounty hunders must carefully learn abount the project they participate in or their investments will be bad and they lost may be not money but time and work exactly.
Moreover, active participants in bounty campaigns devote much time to disseminating information, completing assignments and attracting referrals. It will be a shame if their work is not paid.
