http://www.economicpolicyjournal.com/2012/10/headed-uptown-in-bitcoin-limousine.htmlCongrats to the guys at bitpay for being mentioned in one of my favorite economics and financial blogs.
Of note: The ability to pay by bitcoin via smartphone is making it much closer to a money. BUT, the key still remains the number of people who will accept bitcoins in payment. For something to become a medium of exchange, it must have near universal acceptance as money, within a region. Bitcoin isn't there yet, by far.
