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.
This kind of thinking is what makes the bounty campaign more complicated for bounty hunters especially the newbies as they will fear that their work and effort will end up to nothing.
But before we conclude anything we should think first if how much the project owners allocate to their bounty campaigns. Usually it ranges from 1-10% of their total coins/tokens but they often offers like 1-3%, do you think this kind of allocation will really affect the price of their tokens/coins upon reaching the exchange? Frankly speaking, the dump of their investors and team behind the project is what makes the price of their tokens/coins goes down pretty badly.
