People don't want to know and learn about crypto because there is a fear of stepping into something new that might change for the better. I've met people who didn't want to know new things and to be able to give them a chance to get better. And I also don't force them to follow me because that is a choice.
I think fear is also one of the motivating factor of learning. The fear of losing will push a person to study the venture deeply so that he can avoid it(losing). I think the more probable reason people don't want to know and learn cryptocurrency is because they are lazy to do it.
I agree that forcing them to follow our lead is not the best move. We should let them decide for themselves forcing them to do things often times have a bad result.
People can overcome their fear by learning more to understand that crypto is not scary. Once they understand more about crypto, they will see the advantages they can get through crypto by investing.
I just assume that if they don't want to start investing in crypto, it is because of their ignorance and not being able to accept new things. We may have met people like that and let them continue their actions.
And one day, when their minds are open and they can accept Bitcoin or crypto and come to us asking for further explanation, we can help explain it to them. Apart from that, we still cannot force them and fully leave the decision to invest in them.
