It depends on my time. I also participated in 5-10 bounty at the same time, but I can only choose one to participate in the forum signature. Of course, I will choose a higher reward ratio. Others I will be involved in the Bounty missions on Facebook and Twitter, because friends in the community will easily see my forwarding and information, so that they will not bother others because of advertising, and friends are easy to accept.
This is my method, I hope it is useful to you!
