This makes me remember Tokoin and tachyon protocol bounty campaign, after hunters are paid they made huge profits from this bounties and still the value are rising and not dumped, so my question is why are other bounties getting ruined after launch? Or after hunters sell their rewards? Probably because they are bad projects, hunters aren't to be blame here isn't it? Good projects will never dumped because hunters sell off
Some projects have a buy back strategy which prevent hunters from dumping and causing negative price effect. I remember REMME, an old project which placed about 1000ETH buy wall just so hunters do not make it dump hard on IDEX wayback. Tachyon really did well, even mooned hard after Bounty distribution and hunters who rushed to sell regretted. Hence, good projects come up with good strategies to limit massive dips, even though they can't completely prevent it.
