So what do you mean causing dump is bounty hunter? 3M bounty allocation is only if there are many people interested in trading this project, I'm sure there won't be a dump and I also think if not all bounty hunters will sell their tokens, some will definitely hold
There are just small proportions of tokens distributed to bounty hunters, so I don't think they have enough sources to dump MYO, especially in long term. They might dump MYO instantly after received their payments, but when days or weeks pass, they will run out of free tokens, and won't be able to dump anymore.
