My thought is exactly like yours, looking at the industry i don't see the need of bounties anymore and the sooner the community realized that the sooner we'll drive away scammers using innocent individuals to work for free and aren't paying them and when they do pay, they pay in worthless tokens that can't easily or will never be convertible. The developers should or can work with other innovative ways of adverting, the exchange is quite a good media to reach a larger and probably targeted audience. It should be utilized more.
