Bitcoin is a fixed point in the set of all possible monetary systems.

Mathematically speaking:

A fixed point is a state that does not change through transformation.

If we go through all monetary systems —

from beads to shells, metal, paper, credit, central banks, QE — we realize:

With each new transformation, the monetary system changes...

until we encounter Bitcoin.

Bitcoin is the first candidate for a monetary fixed point,

because no political or economic operator can change the system.
