such projects appear a lot, actually the reward campaigns no longer make money like they used to be, when most of the projects didn't have liquidity for their tokens, a lot of old bounty hunters quit. I think projects should pay bounty hunters with stablecoins
Paying with stable coins is only possible for those projects having ICO already done prior to the start of the signature campaign but most of the campaigns actually require bounty campaigns to get highlighted in the community and then they get their ICO listed on the exchange and after it they are able to get the funds to support and develop the project. My advice is to have a promise to buy back the tokens from the community at a constant price, this makes the developers more trustworthy and the campaigns also lucrative for the bounty participants.
