Yep, definitely. It's unlikely that the transfer process consumed the entire duration. Do you know when exactly the casino initiated the transaction? Any verification or other details worth mentioning included?

Could be handy too.

Why is a deposit required for account verification if I already have a winning balance?

Greetings, the deposit for verification is usually for verification of the payment method. It is quite common in every casino but the important thing is that it is often a minimum amount. How much does the casino ask from you?
