If you haven't noticed withdrawal of coins needs to be confirmed through your email. As it is obvious, it's being implemented to add one more security measure to our profiles.
If anyone did not verify his email address, that can be done on profile edit section https://musicoin.org/nav/profile where you need to do the following:
- Enter the email address into the corresponding field.
- Hit "Update Profile" button.
- Click on "Send verify email again" (bellow email field)
- Open email that has been sent and click on a confirmational link.
After that, your email will be connected to your Musicoin profile.
