The idea of using Bitcoin at this point in time to physically purchase goods and services is ridiculous given the speed of speculation. Hypothetically, why should I pay someone 0.5 BTC at $1000/BTC if in a couple of days I know it's going to rise to $1000+/BTC? Obviously the seller is betting on their value going up, but at this point, there's no reason to do anything except hold onto your BTC until the market actually stabilizes or even crashes.
