I think bounty and airdrops kill projects, yes. Because everyone sells their reward immediately and price dump really fast
That is what you think. THis is a total wrong notion about bounty hunters. Let's be realistic:
What are bounty hunters paid thisthese that would make them dump the price of the coin/token they are paid?
The fact is that bounty pools these days are not just worth it, except for very few projects. Even projects that provide good amount of reward to bounty hunters do not dump.
Most times, you see coins/tokens dump even when hunters have not been paid.
