I heard that what most bounty managers do is to conduct the bounty project and later submit to projects teams for distribution, is this not why some projects never paid bounty hunters?

 +The job of a bounty manager should be the guide standing between bounty hunters and project teams
+ Bounty managers should be the ones to hold on to the project tokens and distribute after bounty ends

Avoid these and teams might decide not to pay or send out half payments to half of the hunters, it should be more like how IEO is where exchange stands between investors and team
