Economic value is always subjective. Dump the "intrinsic value" talk. Gold doesn't have intrinsic value, but it has certain intrinsic properties (and a relatively limited supply) that *therefore* make it valuable to humans. Bitcoin is the same in that respect: it has certain intrinsic properties (and a mathematically fixed supply) that *therefore* make it valuable to humans, and therefore it useful as money.
Side note, I don't think we should talk about moral "values" as if they too are subjective, dynamic, and situational. They aren't. Nature is normative, morality too is normative -- "essence precedes existence." IMO, we should speak about "virtues" in the moral sphere, and reserve "value" for the economic sphere. Someone speaking about "their values" it's awfully similar to my mind as them speaking about "their truth," and it's po-mo nonsense.
