According to this; we can all do this. Create massive amounts of rigs on betarigs, each one with 0.0001 higher price. In the back have only 1 rig. In rig config, set highest priority pools to ones with higher price. That way your rig is constantly hired, for no work time customers need to fill ticket (if they do - some don't). You can gain a lot that way. How do you fight against such manipulation?
