Everytime I see kids use tablets and smartphones like a pro, I know that the world is ready for cryptocurrencies. The people of this generations are so advanced that they are much easier to teach on how to use bitcoin and altcoins rather than the old people.

But the thing is, not all people have reached by the civilization therefore it is hard as of this moment. We can say that the world will be ready if and only if all people have an access to the internet at the same time know how to use gadgets.
