I thought that even the most ardent Bitcoin supporters had abandoned the idea of advocating it as an actual currency, and were instead focused on it as a store of value, aka "digital gold". Bitcoin's technical and design limitations (slow transaction speeds, inherently deflationary) make it simply unworkable as a widely-used currency. Further, any country electing to use Bitcoin as their national currency is forfeiting control of their monetary policy, and thus control of their economy. Poor countries who do this will doom themselves, as they will be unable to devalue their currencies to make their exports more competitive and thereby build up their domestic economic productivity. This has been one of the biggest problems with the Euro. When you have large and powerful economies like Germany using the same currency as small and weak economies like Greece, the Greeks are then unable to utilize monetary policy to jumpstart their economy, and sink further and further into debt as a result.
