I did some digging.
- You have 2 wallets per account - CRYPTO and EUR
- You pay with EUR when using their card - so you have to exchange from CRYPTO to EUR before using it
- The more "investments" you make before you get one of their cards, the more cashback you will receive as a CRO
- You must keep that CRO for at least 6 months before being able to withdraw / exchange - coming from the card investment / cashback
- The biggest disadvantage - their card does not support apple / google pay; I visit several countries a year and there are many dangerous places where you don't want to have your wallet with you; or do some adventure / sports and you can only take your phone with you
