I'm more curious as to how they define the value of Uber. If it's based on the assets that are provided for the service then I personally think that's a bad measure since those kinds of "assets" aren't even really owned by the company. Now if it's based on revenue over a few years, that makes sense since it does have a world-wide market and is in use throughout many cities and locales.

And you're wrong with the cap, Bitcoin is listed at $112B.

What's wrong with the picture though?
