I took part in some bounty campaign and the result was nothing. It doesn't work and the payments are so little that makes it impossible to even transfer the tokens and sell them.
I have been paid some of them and it was tokens worth $1-2 for social media campaigns. This is a big joke for bounties and I wonder why are people still doing this.
You have written this post just to increase activity meter ? Because based on your post history, I can see that you have ever participated in any bounty campaign... Or, you have participated in bounties that did not run on this forum. Now wonder then your results are so low and you have such an opinion.
For example, I have participated in YOUenging Facebook/Twitter/LinkedinIn campaigns. Havent yet sold rewarded tokens, but today they are worth around 150 USD. And the project havent released its app yet.
