More likely bounty hunters is also some sort of investors, though no money is placed but they probably put their trust into something that worth to hold.

If a token is good no matter how the bounty hunters dump the token it will still bounce back. On the side note, investors are silently dumping their token since they lose trust to the project and it's time to cut loss. We can't put all the blame to each other because the reality hits us hard that the team has a full responsibility to make their token stabilize, they should be the one thinking how their token survive in this kind of environment. We put trust to them so in return they should be doing something worthy.
