I don't consider myself an egoist, although some time ago, I didn't tell anyone that I was engaged in cryptocurrency. Just my friends were far from this and considered that crypto is a bubble. But when they found out what I do and that it brings me money, they came to me to learn more about crypto. I, of course, tell but I don't force to invest.
I know people who entered into crypto due to FOMO and they lost in the start and later on made millions and I am happy for them because they have multiple purposes and do charity works with the money earned as well as diversified now.
