Actually I'm always scared of introducing my friends to this crypto investment reason is because most of them are not educated enough to read and understand how the market works, I'm always scared because they can go with it the wrong way and if anything should happen to their money I will be hold responsible. that is why I always avoid them, not everyone who can bare the risk mostly when it has to do with money they're always careful.
Most of us are scared when it comes to introducing others to bitcoin, you might get mocked by that group or they will be a A-hole and call you responsible when they lose money.
That is why I only tell others about crypto if they are interested to know about it with disclosure that it is a risky asset class to dive into. If the impulse for knowing about something comes from the opposite side, that is the best time to teach someone about that thing.
Still this problem will exist in future too because who wants to invest in something that cannot be felt or seen, they think its a scam in the first place, even though the price is high now.
