How can I change my bank account?
Currently each bank account can only be used in one bitcoin.de account at a time.
To change your bank account please login to your account and navigate to 'my Bitcoin.de' → 'Settings' → 'bank account' and chose the option 'deactivate bank account'. Please note that deleting a bank account is only possible once all trades of your account have been completed.
Afterwards you will be able to enter and verify your new bank account as usual.
