My own fact about bounties in 2019 is that lazy people won't make a dime from airdrop or bounties because scam projects are every where nowadays, to be able to make money now you have to work very hard by joining many airdrops and bounties, surely one or two will turn out with positive result
But don't you think that 1 - 2 campaigns won't pay you enough. Those campaigns might not worth your time spent on. Imagine spending hours and hours but in the end you get only small amount. Yeah! Lazy people won't make money now or never. If they do then it's still by some luck.
