If you want to spread bitcoin awareness, there is no better measure or rule on how to best share the knowledge but please don't advice someone who is financially imbalance to invest in bitcoin especially the ones that have been hearing but don't know how it work and how it has performed in the past. I have a friend who motivated a friend to buy bitcoin and teach him some basics out of pity that the person wasn't okay financially but made mistake of buying at the top, now the new guy is the type that wanted to yield something quick as he had heard how bitcoin has been changing life's, it took grace to convince that guy not to sell, he is still holding as I sometimes view the wallet address time to time.

I have a friend who teach in a high school and when I'm less busy, I go to his place of work and anytime I see him teaching in his class, I used that opportunity to give his students some basic things about Bitcoin, not to buy bitcoin for now but to show them the economical aspects of Bitcoin and it importance. I don't want them to finish school with hope of relying on bank cards and government to approve a payment before they can spend. The class was interactive and I am impressed with their questions and some quiz responses, that's my way of teaching bitcoins, they will one way influence others including there parents one day.
