Devs should stop blaming bounty hunters for dumping ,they work hard to promote your projects and they have every right to do what they like with the tokens if this is really what you don't want then
Don't pay bounty hunters in your tokens ,pay them in USD ,USDC or ETHEREUM to avoid dumping your tokens and that will have positive impact on your tokens ,dumping will always happen and if the project is a strong one then it will quickly recover
It has been suggested here severally, due to greediness of team, it is difficult for them to use it to pay bounty hunters, the value they place on hunters is nothing to right home about, bounty hunters have the right to sell anytime, team work and reputation will justify if they should hold or not.
