The best solution if they are afraid of dump is they do a gradual distribution of the bounties, maybe by this for sure many happy people will praise them since they do the distribution in proper way.
Mostly the fault is on the developers end. Often they just give out too many tokens, resulting in an immediate dump after listing on exchange. Therefore, they should hire experienced advisers and managers to avoid such situations.
Gradual distribution is also a pretty good idea in my opinion.
I also saw propositions of % bonuses every three months for example for those bounty hunters who decide to keep the tokens.
