It's a complex phenomenon. There are various jurisdictions with their supply/demand for Bitcoin, affected by regulations, government (in)stability, the exchanges' ability to handle heavy volumes, etc. So Bitcoin's value doesn't diversify away from nation-specific risks---rather, it aggregates across the risks of all nations, which would tend to reduce the risk, but it doesn't exactly get away from it. Presumably a Bitcoin in North Korea is worth little to most North Koreans because they have no means of accessing the Internet or leaving the country to redeem its value. Should Bitcoin transactions be banned in a given country, but citizens retain mobility, Bitcoins will keep some value in that jurisdiction because of the ability to drive to a neighboring country, buy/sell Bitcoins, and return. Of course this will be subject to limits on cash flows across borders. Has anyone made a map showing Bitcoin prices across the globe?
