You know i tried to register&login with my email in this site. Then i tried to set my withdrawal setting. the funny thing is the system still ask me for my email verification.
I do verify my email and complete my registration properly. Do verify your email by opening the verification link on the same browser which your 1win account was open?
Try to copy the verification link the browser that open your 1win account. Probably you failed the email verification on the process. Best option is always contact the support if the method I mention didn’t work.
