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, I completely brainfarted there, we are talking here 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.
