This is just a wish, I hoped for it and asked around but yet it seem impossible, the best thing in ever wished for on this forum is bounty projects should start paying in bitcoin or stable coins to bounty hunters, doing this will avoid dumping their tokens buh .... I guess its not going to work since most new projects have no money to do so. they are better off paying hunters in their very own token, damn!
I also hope the same with you, but as you said that it is very difficult to happen, because in my opinion companies don't want to lose their money by paying bounty using ETH, Bitcoin or stable coin, other than that companies pay bounty using coin from their project to make the coin has a volume on exchange.
