Any casino that relies on people reversing withdrawals can close for me. If their profit margin is that low, then chances are they won't pay you if you get a big win anyway.
Heres a mad idea, when I deposit it takes seconds. How about when I withdraw its done in the same time it takes to take the money.
Would be nice but the casino has to check for certain things like bonus abuse and the like . And even though each account might take only a few minutes to check if theres a long queue of people withdrawing it will obviously take a bit of time . I think a couple of hours is reasonable enough . A few sites manage it much more quickly that that but its usually when u are a more established regular player
