though bounty cant be predicted whether one can make profit or not, mind you not all bounty, just like me have upto four campaign done, and have not receive reward and have receive reward from some, and move one; because i do two or three campaign at the same time (I mean social Media), bounty is like like that. that its why its always good to do basic analysis before participating in any bounty, but most the time because of the anxiety we forget about that, and jump into the campaign.
so that is it.
