Are BTC withdrawals not being processed right now? My withdrawal request has been pending for over 2 hours.
Do you have 2 factor authentication enabled? If not (you should), did you click the link in their email confirmation? I think they may have changed their BTC withdraw policy within the last two weeks:
"For security reasons, withdrawals will be automatically processed only if you have enabled OTP authentication (Account Security menu). Otherwise, you will receive an email with a confirmation link to approve the withdrawal. Large withdrawals will be processed manually."
