The crypto space has experienced so many bullies, and it has been mostly attributed to bounty hunters. Whenever there is a dump; people raise fingers, and attack hunters as the cause of the dumps.
But when you consider most recently hybrix token; the investors got their dividends, and they boldly dumped the token from 3.5$ to 0.5$.
This reinforce claims that no matter how much bounty hunters earn; it is not enough to close down the trade market of crypto coins.
I am on your way. Yes, bounty hunters are not at all the reason for dump because it's a free market anyone can do whatever they want. If the devs are too concerned about the dumps happening after bounty rewards are distributed then they should never go for bounty program. Yes, that is the only way they can avoid dumps when they are not having good project to withstand any kind of dumps.
Like many people have already mentioned, a highly potential project will not bother about dumps happening in the markets time to time because good projects will be having continuous supporters/investors who will give it pumping when there are dips to enter. When devs are not developing a good project which is not attracting investors continuously, they are simply going for blaming bounty hunters for the downfall of market prices of their coin/token.
