Nathan's column: How many for an extra life?
I've been hearing a lot lately about Bitcoins, which are a kind of Internet-based money that's real in the same way Kate Upton is really my Internet girlfriend. Which is to say, if I try hard enough I might be able to convince a few nerds, but most of the world will just look at me like I'm crazy.
OK, that's not entirely true. Bitcoins are real in that they are a thing that exists. There is a finite number of them, and you can spend actual cash to acquire them.
