A good way would be to just gift someone some bitcoin, which would make them look into wallets, how to safely store bitcoin etc. It's a much better incentive to make someone learn about blockchain technology then just lecturing people about it.
I remember doing it and they just became interested when the price increases during 2017 but when the price falls they get not interested. Crypto is only for those whose willing to risk at the same is eager to learn,even we give many details or even free BTC many were not an investor or risky type of persons as they fear some loses.
I only teach bitcoin or tells it only to people who shows interest, I do post sometimes about topic in crypto and only those who will ask and seems interested the only time I will discussed how it works.
