Bounty hunting is still fair, they just requires more energy unlike in the past where you can rely on few projects you promote, to get something good out of bounties today you have to do a lot of work and join many bounties
Increasing the quantity of the bounty campaigns will lead to the same result as we stuck in this process. The current bear market is the first cause of the low demand by the crypto investors and people transfer their crypto earnings to the traditional markets. Bounties will stay at the poorest dip until the market recovery.
We saw an important recovery during the last year and despite of this icos were still getting poor results and bounty campaigns were a failure, I can assure you that even if the bull market happened tomorrow we are not going to get a recovery from those projects because investors no longer trust in them as they know there is a huge chance they are going to lose their money and until this changes then most likely we will never see the same success that bounty campaigns had in the past.
