If I understand correctly this is only VIRTUAL master cards (not physical plastic cards), and you can't use them on ATM as far as I know. unless they invent some virtual ATM's

Ah yes you are right, that was a total brainfart, we are talking here about virtual cards.

We need more explanation and asnwering some questions from CriptoDebit.
Yep, many questions about how this actually works and about potential issues. I see that they have telegram contact so in case he doesn't answer here soon I'll try to contact him that way. In his other thread OP wrote that they are live for only couple of days with several dozens of cards issued so far so I would be very careful with this.
I forgot that we also have a post here in the exchange topic, I think I answered your questions in the other topic. If you have any more questions, let us know.
