Ooh, a post by a Keynesian telling us all why Bitcoin isn't money. I'll make sure to pay lots of attention to this one.
Actually I'm saying that Keynes's idea to bring a better monetary system was to create a concept that bitcoins is representing today. He didn't named his currency bitcoin, either he didn't have any idea of internet and stuff, but the concept are the same.
