Bitcoin's popularity did not suddenly rise, it took years of tireless struggle and evolution to gain popularity. Bitcoin's popularity didn't suddenly spread worldwide after Satoshi Nakamoto invented Bitcoin. Rather, after the discovery of Bitcoin, few people knew about this Bitcoin, then with the evolution of time and necessity, Bitcoin has now become the most talked about digital currency in the world.
I tried to explain the matter with a very simple example. For example Bitcoin Forum was created in November 2009 when there were only four new members of Bitcoin Forum now Bitcoin Forum has 3516956+ members.
November 2009 bitcoin forum new members 4
November 2010 bitcoin forum new members 374
November 2011 bitcoin forum new members 1993
November 2012 bitcoin forum new members 2708
November 2013 bitcoin forum new members 19683
...........
...........
..........
November 2017 bitcoin forum new members 97283
So today bitcoin forum members amounts 3516956+

https://bitcointalk.org/index.php?action=statsThe popularity of our bitcoin forum was close to zero in the beginning, now the popularity of bitcoin forum is very high worldwide and constantly new members are joining the world and trying to occupy an important place in the world. Just like the Bitcoin forum, the popularity of Bitcoin will not be created in a day, but more time is needed to spread the popularity of Bitcoin around the world and more advertising is needed to spread the popularity of Bitcoin widely around the world.
