In your thinking, do you believe that bitcoins are going to make a lot more headway and get accepted at a mass level given that bitcoins are much more than merely printing currency in the press. Would you consider bitcoin as 'money' and to what extent do you believe they qualify as 'money' in the context of 'a medium of exchange and store of wealth' and also 'divisible' much like any other currency? What are the barriers, if any for bitcoin to take hold on the world stage?
