When you are buying stuff with your Monaco card do you need to sell coins in app manually to fiat before purchase, then top up your monaco card with fiat to spend your money, or is monaco app doing it automatically so you dont need to sell your coins or calculate how much you need to sell etc. ??
I've seen on reddit a very similar question, and I believe the answer (from a Monaco rep) is that you can top up manually by selling coins, however, the app should have a function that says 'top up to X amount if you fall below Y amount' or something similar. From memory, the reason provided was that visa currently doesn't allow the instant sale of crypto through their system - it needs to already be in fiat when you swipe your card.
If you can automatically top up, than that should make things a bit easier at least. Maybe in the future it will be possible, or instead they could open up a credit line based on crypto assets, that sort of thing.
