Telling your them "Study Bitcoin" is a great approach but where I think there might be an issue is where they are going study from. More often people go watch mainstream media videos and CrYpTo youtubers who want to scam them with *shitcoins and such. Plus, must people are still scared of Bitcoin either due to price volatility or what they've heard about it from the media, that's one of the reason why it's so hard for them to find motivation in studying it, but by having some Sats on their smartphone they can kind of see that it's not that scary and eventually see the value.
