Well, if there is someone who just bought Bitcoin and then just held it for a few years and didn't study it, he can still be rich in what he does as long as he has at least 1 Bitcoin or half of Bitcoin. Now, even if he doesn't study it for sure, he can still study it because there is and still is someone he will encounter talking about bitcoin, or maybe some of their friends are talking about this too.
But even if it's like that and his bitcoin is only held, as time and days pass, there is an increase in the value of bitcoin, especially if Edi studies it. For sure, it will add knowledge to the holders as well.
One of the examples you said might have happened to someone in this world regarding how to hold Bitcoin, but in general everyone who holds Bitcoin definitely has a little knowledge about Bitcoin. At least they know how to buy it and know how to store it well even though they still haven't learned all the knowledge related to Bitcoin, because they can learn this over time after they hold Bitcoin. There is definitely more curiosity about Bitcoin among those who already hold Bitcoin in the amount you said.
