I remember hearing something about a bitcoin credit card. Like, one that you pay for everything with fiat on credit, and then you pay off your bill in bitcoin. So you never have to hold fiat if you don't want to.
What's the best/most reliable credit card that does this?
Maybe it will be possible to have a bitcoin credit card but bitcoin is not consider to use as debit card by bank. Bank is always looking for their security when it terms of debit their only accept a fiat. But its a good thinking to have bitcoin credit card.
