I think intrinsic means in this context "valuable for something other than bartering with".

Gold has intrinsic value in electronics. It is used for electrical connectors due to its corrosion resistance and conductivity. Tiny golden wires are used in packaging integrated circuits (connecting the ICs to the pins of the chip).

Bitcoins have no such intrinsic value. They can only be bartered for something else.

Even fiat has intrinsic value: you can burn bills for warm.
