I honestly have a problem with this issue why most people consider that bounty hunters are the most dumpers. As said already, mostly 1-5% of tokens are allocated for bounty and why are we the bounty hunters always blamed for dumping. Don't we the bounty hunters worth what we do and wish to hold to get a good value? Those who hate bounty dumpers really don't read more and haven't come to the idea that only few percentage is always allocated to bounties.
It's sometimes overwhelming, some bounty hunters also contribute significantly to these dumpa. Maybe it's because they're doing it for living and have no option than to sell off. It doesn't matter to them if a project has future, all they care about is make the monry and move on. After all everyone does what pleases him/her
