Scarcity is not meaningfully correlated to the units chosen to represent total coinage in cryptocurrencies. That's like someone saying "you can have 1 pint of this beer or 568ml of this other one" and you deducing that the 1 pint must be "scarcer" than the 568ml beer. The units involved don't really matter, it's what's in the glass that counts - i.e., does the cryptocurrency provide utility and value, or does it not.
