I dont know how they will do it but Visa network companies does not convert crypto currency directly and most of the transactions are done through registered banks.So I dont get how this visa card will work on any ATMS if there is cryptocoin insideit but may be the card only will hold the International currencies not alternate currencies.
This is too I think but I'm dizzy. Maybe dev already have his own plans to run it, we'll see next from this project
Described monaco will work with some reputable banks may be one of them exchanger coinbase or something else
So the exchange rate BTC / ETH / ECR20 is changed to DOLLAR / EURO
Anyway they have a monaco app maybe there is a system that can manage all.
