I honestly have no idea. Like austinEV said, unless I can buy a sammich with BTC, I'm probably not going to be diverting any of my currency into this yet.
I just think the whole thing is a fascinating from a sociological and psychological perspective.
You can convert your USD to EUR, and then back to USD and buy the sandwich. How are Bitcoins different? Is it because the exchange rate between major currencies is determined by methods that ultimately rely on open markets? And since so few merchants accept BTC it's hard to argue there's an open market? But can't you exchange BTC for USD any time you want? Just trying to understand... Maybe I'll go make a sandwich and think about it.:biggrin:
