The "only" thing left? Housing/land has long been the most durable store of value in history and that wont change. It's not as liquid as Crypto and requires laws to enforce private property. But if society collapses, we'll have bigger things to worry about and even Bitcoin can be "seized" via violence/coercion.

> and that wont change

depends on location/country etc. Houses are out of reach for most millenials worldwide and i don't see that changing either
