Betting exchanges offer the same opportunities to bet as a bookmaker with a few differences. You can buy and sell the outcome, you can trade in real-time throughout the event and you trade out to cut your losses or lock in profit. Bookmaker operators generate revenue by offering less efficient odds. Betting exchanges normally generate revenue by charging a transaction fee."] } } }
