Hi all. I took part in more than 3 hundred bounties in two year. Last half year there are no pay from project to hunters. Maybe bounty will die or it's transformayion in something other 
I think you should be more selective of the bounty campaigns that you join. Research or check carefully details and feasibility of the project to have at least a big probability that you will be paid. Check also the team running and managing the project as they will also give you an idea if the project is legitimate or not. good luck
