Well, the most important question is if your daughter has any interest in bitcoin, does she want to buy, spend, hold or trade bitcoin, or use it in any other way. If the answer to that question is yes, then you can basically tell her about bitcointalk, a discussion forum where she can discuss with other bitcoiners. She is 18, she will figure out everything else herself.
That's exactly what came into my mind after reading the opening post. You really cannot make a GenZ get into an OG forum with only texts and no visuals unless they have some interest in the actual reason why this or such forums exist, and that reason is Bitcoin. A person who doesn't have any interest in Bitcoin or cryptocurrencies will never have any interest in forums where things related to them are discussed only, or mainly. You might introduce them, and they might not say that they are not interested only for the sake of formality, but they won't show any interest, or do things with interest in your absence if they are not interested themselves.
So, I also agree that if she is 18 years old and mature enough to understand everything herself, you don't really need to teach her anything. If you get a positive response for the question you ask her about her interest in Bitcoin and cryptocurrencies, you only need to ask her to check the forum out and tell her that it was created by the main himself (Satoshi), and that might make her more interested and she might join and start reading through with interest. She will learn everything else over time, or she will ask you herself whenever she wants to understand something.
