Hello,
I'm here to explore the demand for crypto debit card.

The basics behind it is actually very simple:
1. You own some crypto funds on your account on an exchange (crypto/FIAT markets) that has partnered with a debit card provider. You'd have to identify yourself (pass KYC).
2. You get the card. It is a basic mastercard  debit card for FIAT payments. No magic.
3. When you use it, it automatically exchanges your crypto to FIAT based on the amount you're spending. You would even be able prioritize the order in which your crypto is to be exchanged the first, the second, etc.

So, would you use one? 
If yes, would such service motivate you enough to open an account on the exchange that is not (yet) one of the TOP ones?

Disclaimer: I'm a business owner in a position to offer such service. Knowing your opinion would help me a lot. So, thanks in advance!
