Register it to an email that you have full control of, e.g. don't use email address linked to your University or employee. Take good care of your email (2fa). Use a domain registrar that you trust. Saving a few dollars each year on domain is not worth the possible complications. If you are enabling auto renew be sure at all time that your credit card is valid. Put reminders in your calendar about exportation dates.
