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's always about the idea of the project. Investors are only dependent on the idea and roadmap of the project, there are no other basis if the project will be successful or not. If the idea is great, they will choose to hodl instead of dumping their tokens and hence pumping the price since other people will also gain interest and buy the token because the project has a potential.
There are also other projects which are only great at the beginning and just dumps after some months. So better set a target price when you will sell your holdings or keep watching the market regarding the price.
