Yes I also think that bitcoin is becoming a worldwide currency and more people are interested to know about it, how they can treat it.
Actually, bitcoin is the new currency and I think it will become world currency in the near future. In addition to that, some country start to use it as currency and they use it to buy the things that they want. I hope many people will get interested in bitcoin and I do believe that bitcoin will become our best currency.
but to me i think bitcoin is already the world currency because we can see that the bitcoin users are available throughout the world and still the number of their users are increasing. which is defiantly making bitcoin as a universal currency. i am hopeful that even in such area specially the backward area where people still do not have their access to bitcoin they will also become able to use bitcoin and get benefit from it.
