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
It probably because these projects have something to contribute to the market and they are not abandoned by its developer after they paid the participants. The future of a certain project lies into the hand of the developers if they don't want to make it successful and fully runs their project, it surely they will go. The intention of these projects (Tokion and Tachyon) might be good and it attracts investors to help it maintain its market price, unlike the others.
