A rather sensitive issue about family relationships or in society, I have also met a number of cases where relatives borrowed money to invest in other asset portfolios. But when I talk directly, I see that they are making a mistake because only investing through a broker is not proactive.
I once saw a funny story about borrowing money. If I lend you money I will lose both you and the money, but if I don't lend you money I only lose a friend and the money remains.
I personally also look at the problem as positively as possible, help people most effectively without necessarily involving money, sometimes it is worth more than losing money, pointing out the mistakes of new people and strengthen yourself.
