How do I change my email address?
You can find an option to change your email address in the settings of your account (under 'my Bitcoin.de' → 'Settings' → 'Email').
Please note that due to security reasons an email containing a confirmation link will be sent to your old and to your new email address. The change of your address will be carried out after these confirmation links have been clicked.
Supplementary guidance:
I can not access the email address that my LoginTAN is sent to.
