Has anybody seen good articles that address the topic of a new global reserve currency and how that role could be served by ecash/digital cryptocurrencies? Especially from two points of view: - China making remarks in that direction, enhancing the role of SDR etc. - Liberalizing currencies in general, from Airmiles to Whatevercoin with simple decentralized exchange mechanisms? (The Ripple/Bancor idea) Following Izzy Kaminska at FT Alphaville (http://ftalphaville.ft.com/tag/bitcoinmania/ http://ftalphaville.ft.com/tag/bitcoinmania/ free signup & highly recommended), but more interested in stuff by nerds within central banks etc.
