Well, I once invited someone, and he managed to own some assets at that time. However, since the price of bitcoin has dropped, I think he has gone out and looked for other investments. Well, he was grateful, but right now, I think he has another job. However, up to now, I don't want to invite anyone, but I just explain what I know. Sometimes, when someone is invited to invest in something, they do something out of line, such as trading with what they can't afford to lose, then blame the person who invited them.
I felt the same way too. I usually tell my close friends about bitcoin way back then, but now I decided to stop doing it because at the end of the day, instead of helping them and be grateful for it, I end up becoming responsible of their losses even if they know from the start that I never fail to warn them how risky bitcoin investment is.
Now, I’m still open to talk about bitcoin only when they asked to, but I make sure not to convince or influence them at all. Bitcoin is a complex investment most especially for those who are not knowledgeable about it, hence investing without prior learning acquisition will only go into waste and lose all the capital being risk. Invest at your own risk.
