Directly? Lots of stuff, especially at Bitcoin conferences like hardware wallets, drinks, food, jewelry, art, books, VPN, mining equipment, physical coins, shirts, socks and a bunch of other stuff I can't recall.

Indirectly? Literally everything I buy, because I'm on a Bitcoin standard.

A lot of people make it a virtue signal to pay for stuff directly with Bitcoin. It's a nice thing to be able to, but it's not the end-all. That day will come, but trying to guilt people into using it as a payment method when they're paying more for the same good is just foolish.
