A private currency is a currency issued by a private entity, be it an individual, a commercial business, a nonprofit or decentralized common enterprise. It is often contrasted with fiat currency issued by governments or central banks. In many countries, the issuance of private paper currencies and/or the minting of metal coins intended to be used as currency may even be a criminal act such as in the United States (18 U.S. Code § 486).[1] Digital cryptocurrency is sometimes treated as an asset instead of a currency.
