Beyond digital scarcity, bitcoin is also the first example of absolute scarcity, the only liquid commodity (digital or physical) with a set fixed quantity that cannot conceivably be increased. Until the invention of bitcoin, scarcity was always relative, never absolute. It is a common misconception to imagine that any physical good is finite, or absolutely scarce, because the limit on the quantity we can produce of any good is never its prevalence in the planet, but the effort and time dedicated to producing it. With its absolute scarcity bitcoin is highly salable across time.
