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
Are the devs blaming the bounty hunters in the plummeting of the price of their token? I think it is normal already for an ICO to plummet its price because aside from the bounty hunters, investors and the developer themselves are selling it too to have some profit.
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
If I'm the developer, I will not pay bounty hunters in any of the coins you said. Take note that launching an ICO doesn't become a successful one 100% so I will not pay them with that coins because I will be in a loss. That is how the developers think so they are paying them thru their own coins.
