A fiat currency is the monetary representation set up by a state, under the management of a central bank. And it serves primarily to provide a single, harmonized means of payment in a given territory. Its value is largely supported by the fact that it is imposed on the population concerned in the form of what some present as monetary determinism. That is, an individual born in a certain part of the world will inevitably become a user of the currency of the government on which he depends.
