That’s a real issue, especially during live events when odds shift constantly. I try to stick to bookmakers that post updates without delays and that let you track your betting history clearly. It’s also worth comparing at least two sites side by side before placing a large wager it helps spot unrealistic odds. Another thing: avoid those who lure you with massive “guaranteed” bonuses. Most of them have withdrawal conditions so strict that you end up losing your winnings trying to meet them. Consistency in odds and timing always matters more than fancy promotions.
