How about offering to pay friends in bitcoin instead of Venmo? Or sending gifts of bitcoin for bdays.
I know BTC is not going end up being the main crypto “currency” for day to day transactions, but it could be a way to get friends in on the fun… I got involved bc my mom gifted me some, and she got involved pre2017 bc a client paid her in BTC. I just took a friend’s class and I want to offer to pay him the $150 in Bitcoin (I would buy them the equivalent value of bitcoin and send it to them, vs actually sending my own bitcoin). If they say yes, they’ll most likely just sit on it. Even if they say they prefer the cash, I feel like it plants a seed that crypto is an active and valuable part of the world now.
