time goes on, time continues to change and development continues to innovate, I remember that there was only a small number of people who believed in bitcoin and including me who did not believe in bitcoin. Now I realize if we can't keep up with the changes then we will be left behind by the times. perhaps the most popular example that ever happened, when nokia and blackberry did not keep up with technological developments now they are bankrupt. And I think bitcoin in the future will be something bigger than it is now, only time will tell
Nokia and blackberry had their own OS and was actually competing with android, but they just can't beat android's technological innovations.
The number of people who believe in Bitcoin today is not half the total population globally yet, so we can't also say that many people have been into Bitcoin now. However, Bitcoin's adoption is gradually increasing as well as it's value.
