What is Fungible?
From a cryptocurrency perspective, a coin or token is classified as fungible when units of the asset can be exchanged or traded one for another. Hence, an asset is fungible when its units are indistinguishable. Fungible means that one asset is identical to another and can be exchanged, traded, or swapped without losing value.
Cryptocurrencies can be used as a reliable digital medium of exchange because they are fungible. Fungible assets have a defined value and are interchangeable with other assets having similar or equal value. The opposite of a fungible asset is a non-fungible asset that cannot be easily exchanged for another asset of equal value.
