What do you know for real?
If a martian wanted to take you to another galaxy, how much of your knowledge would apply?
Silver is at least used by industry,
But gold is effectively without intrinsic value.
Bitcoin is definitely only worth the asserted value.
I recall a guy literally trying give Bitcoin away in 2011, and nobody wanted it.
It’s only when many people clap that they can fly.
It’s only when you’re on earth that a mile or a kilometer measures distance.
Once that martian comes, our shared knowledge becomes far more uncertain.
