I still don't know anyone in real life who actually understands that BTC is scarce. They always bring up CBDCs and say how they will 'compete' with BTC lol.
And btw, some of these people have phds in math/science. I think we greatly underestimate how little people understand about this when it is so obvious to us. I think that even when BTC eventually becomes widely adopted people will still not comprehend the scarcity; the underlying economic forces will drive it to be adopted even though that conscious understanding by most will not be fully there.
