Tough question beacuse limits are always different. Depends on the bout. If its a normal ESPN type small bout there's no telling. Most only take only 500-1k a rattle and its readily available.
Bigger bouts like DLH and Don Best Bouts......
Hollywood/Pinnacle/Greek/Sportsbook.com/Grande all take anywhere from 5k-50k on a big matchup.
It's really hard 2 say........ the aboves may take more than that if they need the action on the side.
