But at least in my opinion the influencers or media indirectly introduce Bitcoin to the public through their content or news.
Oh, for sure. And what's more, this type of videos has a particularly great effect, as they have an element of shaming. People who don't know what the Bitcoin is, or how much is it worth, are made to look stupid and risk others making fun of them.
So if you're completely ignorant of Bitcoin and come across that video on social media, you're more likely than not just to look Bitcoin up and get to know the basics.
