I am sure you are not looking at this thing properly. I mean there are huge number of bounties already going on. I see many bounties coming out every day and getting listed on different bounty platforms as well as within the forum itself. They are so much in number that they confuses me as to where I should enroll myself and get benefited from it. However, there is surely decreased number of legit bounties, and the one which can provide us best deal in return to our work. So in that way you can say the number of legit bounties has decreased.
