You have a ton of credit cards that you can use to pay with btc atm
Everything is accepting btc as of now

I do wonder which card company has big enough limits to buy a Tesla in 1 go tho lol!
As said before in this thread, that point with BTC is to cut the middleman
(the card is a middleman that sells your BTC to fiat, so you don't really buy anything with BTC)
