If you can't find the right bounty then we should not participate that kind of crap bounty, but doing this kind of crap bounty means wasting time and data! I myself always keep a close eye on projects before work, try to find potential, find out about the team. If all things speak for me, then I start working. Try not to waste time on day after day. Even though I've been a victim of a lot of bad projects, I've found a lot of good work after that.
Did you find any good campaigns at this stage? I also search for bounty based on my experience, learn everything about the project but at the current stage I don't see any projects that are really good and worthy for us to participate in.
