The most meaningful things in life require work. This has been an observable fact since the dawn of human existence.

#Bitcoin 's consensus mechanism, "Proof-of-Work", is a digital manifestation of this real-world principle.

This is also why the dollar, euro, peso, and all other fiat currencies inevitably have and will be guaranteed to be worthless over a long enough timeframe.

They require no work to produce and can therefore be easily created to satisfy the interests of those who have a monopoly over them (central bankers, governments and whoever else is in the club).
