very easy . I let them, and then they see what I can get after getting to know bitcoin.
they would be interested in and start using bitcoin. simple steps that impress them against us.
I would never boast my earnings and winnings to anybody and i would not bother whether someone is making money with it or not but someone really wants to know about it and are really interested to know more about it ,i would be happy to explain everything to him rather than showing him the way to be someone who he is not interested in.
I do try to talk to people about bitcoin and other crypto currency when they ask me about the recent post or share I did on my facebook page and some of them are interested, some doesn't. I try not to talk much of the income I get but sometime talking about making money through crypto does grab their attention at least for a short while. Whether they want to follow your path or not is their sole choice.
