Well, one question to ask is if the company can actually cash out their crypto holdings at the current market price? If they have substantial holdings of thinly-traded crypto, the answer is usually "lol".
Faith in the company matters too. You can't compel them to sell, and if you think the company is going to slowly drive itself into the ground, you probably don't want to give them your $$$. There are quite a few companies that traded below their book value for that reason. IIRC, Kodak is a current example. Want to bet on that?
I find Wall St. baffling for all the usual reasons, but this one is too rarely discussed.

Businesses (or parts of) can have negative value - still worked out pretty well for the execs there.
