Auto Bid - If a person does not put in a bid, it will use what was used last round. If they do not have the points to cover that amount, it will use as much as the user has left.
So if Alesh was bidding 671 points per round, but last round only had 350 points left - the auto bid would place the bid for only 350, not the 671 since they do not have those points to cover the bet.
