Maybe they see the coming crisis, where Bitcoin takes over. When that happens, their junk will be worthless to collectors. Why? Global turmoil in a full fiat crash will make their junk worthless, because people will be scrambling just to stay alive.

What are they doing with the cash they get for their junk while their junk has some value? Turn it into something that has lasting value. What has lasting value? Gold, Bitcoin, land, anti-aging, perhaps a self-regenerating stronghold where they can live off the land and survive. Maybe they are buying armaments for self-protection from the starving billions.
