Sportsbooks require multiple rollovers of deposit before a bonus is paid. For many gamblers, this may be risky because losses from betting might exceed bonus. But during Septembers, there is a limited time to safely earn deposit bonus from some sportsbooks that allow moneyline bets on huge favourites. At Pinnacle and thegreek, 28+ points favourites for NCAAF are available and never seem to lose. However 21 points favourites have losted before. The payout is low from safely risking entire bankroll but earning the bonus is highly probable.
