We are getting there bit by bit. Although it's not that fast as most people hope, we are climbing to that what we call "mass adoptaion of cryptocurrency". There are many news and articles here in my country (Which is a third world country) that states some stores are accepting Bitcoin now. Even a Celebrity made his own cryptocurrency here. There is even an app that lets you buy load, buy, gift cards, buy game credits, pay bills, and anymore.
Here's the articles:

It's getting more viral with every day. Is mass adoption on its way?
In talking of the whole world mass adoption then it will only become possible in rich countries but expecting mass adoption in a poor countries like the 3rd world countries then it is very impossible as not all people know how to use the Blockchain specially the poor in education which is very important for the adoption of Bitcoin.
That's where you are wrong.
