Stayed with a friend of the family in Tennessee a few years ago. He had a debit card that used some other currency. I can't remember the name of it, it wasn't crypto to my knowledge. He took us to a restaurant that accepted it.

I think he said it was based on "work" as it's standard, and explained how it could be made and how people could get it; but I didn't really understand.
