Bitcoin did not spread because of social media, but rather because it provided a solution to an economic problem, whose features began to appear in the year 2008 accompanying the mortgage crisis, urging that Satoshi did not pay much to promote this technology, unlike what is happening now, for example, TikTok paid more than a billion dollars in one year To promote and advertise, something that has not happened in the history of Bitcoin.
If your service is good and solves a problem, it will be lucky to spread for free.
I agree with you because a lot of technologies also came out alongside Bitcoin and have not gotten this popularity and adoption as Bitcoin did. But on the other hand, we can not dispute the fact that the existence of social media platforms has also played an important role in acting as a catalyst for the mass awareness and adoption of Bitcoin today.
