In my opinion, bounty and airdrop hunters didn't kill the project.
They just want their rewards after doing task.
If you think kill project is the fall of price after list exchange, there is not bounty/airdrop hunters fault.
Because most of crypto project is like that.
Discounts kill most of the projects to be honest, project team give attractive 30% even 50% offers for early investors, those people are the one dump the tokens straight away when it listed on exchange.If bounties seems killing the project then better the project pay in bitcoin so there won't be any dump on the token's price from hunters.
