I stand in agreement with Lucius on this one. Even for adults, that's a difficult thing to convince, let alone when that person has a parent who needs conviction beforehand. I can imagine most of the parents hearing "bitcoin" and depicting this as the "bad darkweb money" or as a bubbled-stock.

Most parents behave protectively towards their children, and I have already written that the mainstream media mostly write and speak negatively about Bitcoin, although often without any basis, considering that Bitcoin has nothing to do with Bankman, Kwon or that scammer from Turkey and many others who are guilty of tens of billions of damages because they behaved like arrogant kids who thought that no one could do anything to them.
Because of such people, Bitcoin gets a bad reputation, and I personally in my environment often hear very negative comments when people talk about this topic. Recently, a fraudster (or just an incompetent kid) disappeared in my country with around 70 million euros that he got from clients to invest in cryptocurrencies, and I don't even have to tell you what kind of media fuss was created about it. In its primetime news program, state television made a feature about it and showed the Bitcoin logo, that is, the logo of a domestic exchange, which has nothing to do with the specific case.
I want to say that I am not at all surprised that in general less than 5% of people today own cryptocurrencies, and even less Bitcoin - the general perception of Bitcoin is mostly bad to very bad.
