yes it might be better if payment by usdt or stable coin for the bounty hanters. but it does not rule out the possibility of the project being promoted to be finally happy with the payment in the form of USDT
Payment by Stablecoin is only good if the bounty manager limits the participants. It will help the participants get a good amount of money from their work, if they are not limited to the participants then I believe there will be a lot of subscribers and eventually each will only get a few cents
