Since bounty hunters are being blamed for the projects price drop,
Why not ask the projects owner to pay the bounty reward in BTC or whatever the investors used to invest in their project?
The team of those projects don't have any money of their own that's why they decided to give you their token in exchange for the services you rendered, sometimes those tokens maybe turn out to be a gem or sometimes it's might just be another shit coin that will be stuck in your wallet,it all depends on the how the project turn out to be.
They've promised their hunters a reward that has a total of $ value on their token/coin but they couldn't deliver it.
Sometimes after paying bounty hunters, most of the bounty hunters dump their reward that's why you don't always get the value they promised after distribution.
I think the BM's could try and convince their clients for this kind of payment if they give it a try.
Bounty managers are not responsible for the success of the project, although BM's can be paid in BTC but for the bounty hunters nah, projects will most time prefer to pay in their own token.
