The fear of dumping often makes the project team fear or avoid the payment of hunters until sometimes after the exchange listing. I wonder why the team make themselves restless on an easy thing like that when they can easily conduct their bounty with bitcoin or ethereum for payment. That will safe them of the fear that the bounty hunter will dump after the exchange listing.
it's natural because the Bounty Hunter doesn't want to think long, after what he got he would want to immediately sell it, because what I know is that the bounty hunter wants to get immediate results from his work that sometimes months that month. different from the investors of the project who want to benefit from price increases.
