Bitcoin has come along way we have seen massive adoption and so many videos, news, and articles about websites and many people have invested and are now using Bitcoin do you think after ten years majority of people around the world have heard or read Bitcoin one time or another?
It is not possible to predict what will happen after 10 or 15 years. But right now, I don't think that more than half of the world's population have heard about Bitcoin. The world population currently stands at 7,500 million and the number of active users of Bitcoin may be in a few million. If you add the users who are not active, then the figure may reach 100-200 million. But even then, I don't think that Bitcoin has achieved a great amount of publicity. I would say that the number of people who have ever heard about Bitcoin may not be more than 10x higher than the number of all users. That would give you a figure of 1 to 2 billion individuals.
