There are times that a project might look very promising, but the outcome of the bounty might be very bad. Bounty managers are meant to fight the course of the bounty hunters.
If the team of a project decides not to pay or delay payment for no reason, some bounty managers keep mute and allow the team to have their way. Meanwhile, we have seen bounty managers that fought the course of their hunters till the end and always giving updates on the progress of things. I have been privileged to witness these two sides.
