I don't. I let them discover it themselves. But if someone asks me about it, I will tell them about Bitcoin, and if I see a positive interest I will encourage them to go into Bitcoin. We are wondering why Bitcoin is has not yet reached mainstream and yet we don't wan't to share our knowledge with Bitcoin in fear of being blamed if ever they suffer losses.
well if they do not learn from you , obviously positive towards crypto and bitcoin
they could go and listen to some retarded people who think it is a ponzi or even worse
this way they could never learn about it or start with a negative image in their mind
so I would advise newbies any and every chance I get
