Glint

If gold is a form of currency, then why shouldn't there exist something like an e-payment system you can use to pay for your daily groceries with gold as its base currency? Turns out there is such a thing. Glint, a U.K-based fintech company lets you buy physical gold through an app and then spend it with Mastercard. You may want to give it a try.
