What comes to my mind when I think of currency is that it is the money being used in a daily basis, the money that is used by everyone, accepted by everyone and recognized by everyone. I can see that Bitcoin has a great potential to be one but not now, at least not yet I can say. It is too early for it to be a currency. It should have the global acceptance and recognition first by most of the governments which is the challenge that we are facing right now, how can the governments of different countries see and accept Bitcoin as a currency. Maybe once it is accepted and regulated, maybe that can lessen its volatility for a bit, maybe by then it can be considered as a international currency.
