Op is actually correct, but it's difficult for developers and bm to do so, looking at the funds already put into the project. But if really it can be implemented, then the hunters will decide if to buy the token or stay with reward. And also the team will be rest assured there native token is not dumped by there supposed hunters. It's a good idea by the op, tho few team do this, but will all project team and Bounty managers do this? And save themselves the fear of dump?
It can be done all they have to do is to take a portion of the funds coming from the sales and pay their bounty hunters or they can pay half in their tokens and a half on coins coming from their sales, they will satisfy bounty hunters, there will be no dump and they get trust of the community, it's a win win to all involved.
