But recently, we have seen social media's putting a grip specially on ICO advertisement and I'm expecting that Twitter will be the next social media giants that will follow what Facebook and Google has done. But as far as being the "single currency", well remains to be seen. Although bitcoin has been gaining mainstream acceptance, but its can getting the needed push because of so many FUD's and attacks from government all over the world. To be the "single currency", every country should adopt it. With that said, I don't see bitcoin to be the single currency, although I'm seeing that a lot of people will used it but it will not be the single currency as Jack would have wanted to be.
