This is right and wrong, sometimes bounty hunters make more than the actual price of the token they got paid with, value increase and the 50$ they made can turn to 500$ or even more, since we are promoting a altcoins, there is no need to be paid in stable coins or Bitcoin, if you don't want this then all you need to do is stop promoting altcoins, because 99% of altcoins pays bounty hunters with their native tokens.
Well, According to those bounty hunters this rarely happens and most of the projects aren't strong enough to be a 10x upon their launch. I personally haven't joined any bounty campaigns for years now because most altcoins that are being paid on these campaigns are usually becoming worthless. Those project who doesn't have enough support from their investors and the community can easily go bottom upon their launch given that the liquidity of the token can easily get drained by the bounty hunters who are selling it on a rush being scared that they will not get rewarded from the time and efforts they have made. I believe that not all tokens survive that given that the selling pressure of those bounty hunters and some investors is just so much for them to handle.
