If the project is so concerned about dumping, they could pay hunters in USDT and I'm certain that hunters would even prefer that.
But reality will always slap us in the face. Most project managers mentality is "Why would we pay convertible money when we can just pay them useless tokens! Not to mention abuse them and treat them like a dog!". I've been a victim of this abuse that's why I stopped doing bounty campaigns that pays in valueless tokens (Though I still consider projects that depend reputable campaign manager and project founder).
