I go back and forth on crypto currency. I like the fact that it's an alternative currency. I hate the fact that it's such a resource (electricity) hog. I like the fact that the government gets upset about it. In the end, though, I don't invest in it because it seems more like gambling on brownian motion rather than strategic control. Maybe I'm wrong.
Anyway, my favorite part of the article is at the bottom: "You've read 1 article this month. You have unlimited free articles remaining because we don't have a paywall." :)
