Even if they locked or unlocked the tokens, it's still the platform and the community support that will have an impact on its the price in the market, if bounty hunters dump their share which is ok with me, but if it has potential, investors will easily pick it up.
Actually bounty hunters share is not much to be considered as dumping come from them,so the investors are the persons dumping their tokens so locking the bounty hunters token will cause the value of their rewards to be declined and next time they may failed to participate on the bounties again.
