That's a collectors' item, like a Penny Black postage stamp. Are you saying that Bitcoins are bought by collectors in that sense? Enthusiasts. Like buyers of Chinese vases?What about comic books? I don't think action comics #1 has done anything but appreciate in value for decades.
I don't think such rules apply, though collectors can set off a speculative bubble as did tulip fanciers in the Netherlands in 1637. But tulip values didn't "merely appreciate" did they? They rose vertiginously and then crashed. Like something else I could name, which went to over $19,000 last December, and is today around $6,600. Don't bet the farm on collectors pushing the price back up again to these bubble levels.
(not 100 but large sums of money compared to their net worth).
