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
I guess this is not necessary when they have confident about the potential of their concepts and hence the success of their project. When you are running your project with the real-time applications then you never need to bother about paying bounty rewards in your own tokens/coins and then about getting dumping out. Because, there will be enough adopters and investors to bump over the times. Only condition is, your project must remain attractive.
Fix the payment not in their tokens then everything will be solved.
This will definitely solve, I agree. But, it may prevent the chances of other investors who usually look for buying at dips. I am a kind of investor who take time to analyze hence I never rush for ICO contributions but I will buy in open market if a project is convincing me. At those times, I wait for bounty hunters to dump.
