As it seems yes, but we are still far away until this comes true. It's not easy to ''make'' all people to use bitcoins. And it will be very difficult to make it a legal currency everywhere in this planet.
Exactly, to implent this all over the world is so difficult, it really takes time to make it as legal currency because as of now there were countries that banned it so for sure it will be hard to implement. But then the all we need is to make the government enlightened by the fact that bitcoin is a good way and source of income that makes people leave the financial problem.
