Gradually Bitcoin being most popular currency in the world economy. It’s usability increasing day by day. I think today or tomorrow Bitcoin will control majority part of total economy.
Bitcoin is not the most popular currency in the world, but it can be in that position in terms of digital currency; it's the most talked-about digital currency in the world, as people have already built their trust in it and are making use of it globally.
I also disagree with you in terms of bitcoin going to control the larger part of the world economy if that's what you meant by that statement.
