it depends on the action bounty hunter, what they do when they get paid for they work, whether they trade or they sell it at once, in my opinion the bounty hunters will not affect the increase in volume
I don't agree with you. Bounty hunters also participate in every trade with buying and selling the coin. They mainly sell for the low profit but I can't blame bounty hunter for their behaviour. They are paid for a job and they deserve to get payment with selling the coin for cash.
Indeed, bounty hunters participate in trading activities, so they also support increasing volume but as you say, we can't blame their behavior when it's their reward, they have the right to decide and the volume they can produce is negligible when we can see the value of a bounty, it is not too big. Hunters do not bring too much good or bad influence on the volume of trading of a project, much of that influence comes from big investors and developers, the shares they own in the project are too big, the waves from trading volume are from them
