A credit card has your private key written on the outside of it.
No wonder the card companies have to charge back 2.5% of all transactions as fraud.
Bitcoin enables you to make a payment without exposing your private key.
Payment fees are virtually nothing.
What an upgrade!
There are few cards without number written on it. The card from Apple, and credit card from Gemini for example. Credit card details available in the app however. I think it’s pretty good step up from traditional cards.
Once you understand bitcoin, fiat credit makes zero sense.
Once you start thinking in terms of pri/pub keys there is no going back!
