  • It is usually considered to have six core attributes: to provide a medium of exchange, a store of value, a measure of value, and must be portable, fungible, and frangible. (Portable means it can be used anywhere, fungible means that the currency can be exchanged for itself without risking loss of value, and frangible means capable of being broken into fragments, for example to make change.)
