Bad idea, I've got plenty of crypto, but I wouldn't pay a percentage of it for a company to get me liquidity to use it as a card.

Just sell some and get a normal card. It's a bad money-wise decision for now.

When they start to settle transactions for the same pricing they do for normal CCs, with the same monthly fee, it's worth it, otherwise, bad idea.

This is like travelling to a country and using your CC everywhere, when you could get a better currency exchange rate by not using it and just getting some fiat. If you gonna take those kind of decisions, why invest in crypto at all?

I know that some people gonna hate this, perhaps because they do got cards or they are the companies which make money doing that.
