As being bounty hunter, one of my bases to choose some bounty program is the bounty manager, because most of the time if the manager are the trusted manager to manage bounty program, there is highest possibility that his campaign are legit and will be more profitable to their participants in the near future  to whom advertise their project, but in the other point managers of every bounty campaign is just one of the bases to choose bounty program because there are a lot of ways on how to predict which project will be more profitable in the near future for their participants.

The following is my based to choose bounty program
