I just read the article and realised that the top users are also from the world economic or political powers such as the US, China and Russia. This is also due to the level of awareness and technological advancement which the citizens have taken advantage of too. You won't expect people from poorer countries to have easy access to such information and technology.
That was obvious and so the only thing that we can best do is to follow the steps of these powerhouse countries, if our country doesn't support Bitcoin or cryptocurrency then we can't do about it but at least we can individually decide to ourselves what to do. Most of the investors of these big countries are seeing an opportunity with cryptocurrency and they are already taking part with it, lucky to us who already believe to the future of digital money.
