Well, it this is really true and going to happen, I am glad.

In 2014 I was writing a book on Bitcoin, which I never finished. In the various interviews I did with influential people at the time (Yanis Varoufakis, Rick Falkvinge, Chris Dixon, etc), when offering my view, I used to say that the tipping point would have been a country adopting Bitcoin as currency, and guessing it was going to happen by 2020.

I was wrong, but not by much. And believing so in 2014 wasn't that common.
