Nothing. Your funds remain safe in your mb.io account, no matter how long it's been since you last logged in. There are no inactivity fees, and your account won't be closed automatically due to lack of use. Your crypto stays exactly where you left it.
That said, we recommend:
Logging in periodically to keep your account secure and up to date
Keeping your contact information current in case we need to reach you
Staying informed about any platform updates or policy changes
Your funds are yours. They'll be waiting whenever you're ready to trade again.
