What Is a Medium of Exchange
A medium of exchange is an item or asset that buyers give to sellers when they want to purchase goods or services. It solves the double coincidence of wants by providing a common, accepted payment instrument across many markets.
Money is the most familiar example, but historical and digital alternatives also function as mediums of exchange when people trust that they will be accepted for future purchases.
