You are assuming that the demand for any cryptocurrency responds linearly to the completely arbitrary total "quantity" assigned: Litecoin can't be worth more than Bitcoin because there are more units of them. That's simply not true.

I am a fan of cryptocurrency in principle, but not of this particular oversimplification that was borrowed from some very sloppy thinking on the part of gold enthusiasts.

Limited supply does not reliably ensure certain price behavior independent of demand.
