How is a property (a shelter above someone's head) in one of the most expensive islands in the world (which is like a Manhattan of Asia) a Fiat asset? To me, it seems quite a hard asset, and an opposite of paper trash.

Do you mean in a hypothetical hyperbitcoinised world, people will live inside the Blockchain?

But yeah, I will conserve my Sats and get rid of my dollars first, unless the landlord gives me a convincingly above market rate for my Sats.
