Standard Bank Transfers take between 1 & 5 days to reach your Betfair account (deposits) or your bank account (withdrawals). After your first Instant Bank Transfer (which can take up to 90 minutes), subsequent deposits & withdrawals are immediate.
The Betfair Exchange connects you with a community of punters, allowing you to set your own odds and place bets directly. Without bookmaker intervention, Betfair fosters a real community that interacts directly with odds, offering you better value and improved odds.
