I don't think there will be a clear relationship with the uptrend and bounty campaigns, as I have observed many new projects are still popping up but they don't know much about bitcointalk but instead it's missions from platforms like zealy,... Actually as before it can be said that bounty brings a lot of profit to the participants when projects can pay users, for many years recently only a few are bringing happiness to hunters, I'm not sure if there will be many bounty projects in the future, but I think we also need to adapt to the changing crypto space about new way to earn free money.
