Bounty hunters are working for projects. They're promoting. They do research about the project. I think they have very positive work for the ecosystem. It doesn't make sense to blame them.
That is just a traditional reason why tokens dump. They will blame bounty huntere wherein time and effort were invested to their projects. What they didnt know is that some of them are investors as well. They could also blame those investors who got a lot of discount and will dump it to get their capital. But see we cannot also blame the team since there are also bounty hunters who will dump just for few bucks.
