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!
We can conclude that the project is legit and serious if they start paying their bounty hunters in Bitcoin and ethereum, but unfortunately like what you've mentioned they do not have the funds or the money to start with, all they have is the IOU token, that will took months or even years to have value or not all, this is the risk bounty hunters are facing.
