Anyway in this case, it's natural that every bounty hunter has this kind of attitude toward the coin/token that they've earned, they did not figure out the potential of every coin they've earn. Basically this is the worst part when one's coin dev launch bounty program,and the better part is, this bounty coin has a limited supply it's already drained actually.

Most of them even don't spend a second to think of potential of projects they got free coins.
They simply want to get fastly free money and get out of boats.
Please do not care of them, good project will not long-lasting affected by bounty hunters and their dumps.
