Personally, if I'm in a coffee shop or any store with some people, I pull out my wallet and subtly show them my Xapo debit card. Then they get curious on what kind of card is that since it doesnt look like the usual Mastercard or creditcard. Then I explain it from there on.
What's your way of spreading Bitcoin knowledge?

I love it! xD I've done that with my phone app, paying with BTC via the scanner.
I could say a good way of spreading Bitcoin knowledge would be to explain it the best you can to people that will really listen, and it takes some people more time than others to grasp the concept - For example: My grandmother (Not super old, but only
just computer literate.) I explained to her Bitcoin over the course of a couple months (she kept saying "I just don't get all this techy stuff") and now about 6 months later she's making good money day-to-day crypto trading
Just start slow and ease into it - Like trying to convert someone's religion XD
