I kept mine and I'm glad. It handles the lingering home-country direct debits, receives the odd payment in that currency without conversion, and is a genuine safety net if a new-country account ever has issues. Low cost, high peace of mind.
Part of me wants to cut ties and go fully local, but I've kept my home-country account open for a few lingering direct debits, the odd payment, and a vague sense of a safety net. Is that just inertia, or a genuinely smart thing to keep? Curious what others do and whether keeping it has ever actually saved you.
