Now one of the main arguments in favor of the "bubble burst" are low volumes on crypto-exchanges. And I completely agree with the fact that the volumes are really low and until the volumes increase, we will not go up.
Yeah it is to be done because we are exchanging from barter system to paper currency and now this innovation will take place and nothing will stop it as many people say that it will never happen, but I say that it will happen and we will see that the whole world will use just one digital currency and that will be bitcoin, but it will take a long time as well.
Same as you I really think that it will surely happen, because now in whole world demand for crypto currency is increasing, each and every country is agree to make it legal because people of country are using bitcoin without any fear of government actions, people have now good ideas of generating money from it, bitcoin is openly acceptable in every market and every shopping malls, so gradually need of fait is getting vanish because digital currency is taking place because of fast and easy digital system in every public places.
