UPDATE: 8bet's manager answered me in Telegram and I got my BTC 30 mins ago. All is good now. I wish continuous success to 8bet and good luck to gamblers.
Glad that you have received your money although you had to wait for few days.
If you dont mind, would you tell us what was the reason of the delayed withdrawal?
Did the manager tell you the reason?
If they did tell you the reason, it will be nice if you can share it here so other players may know so they can avoid it and know how to solve it.
