### The Basics
Property of a currency whereby two units can be substituted in place of one
another.
Fungibility means that two units of a currency can be mutually substituted
and the substituted currency is equal to another unit of the same size. For
example, two $10 bills can be exchanged and they are functionally identical
to any other $10 bill in circulation (although $10 bills have unique ID
numbers and are therefore not completely fungible). Gold is probably a
closer example of true fungibility, where any 1 oz. of gold of the same
grade is worth the same as another 1 oz. of gold. Monero is fungible due to
the nature of the currency which provides no way to link transactions
together nor trace the history of any particular XMR. 1 XMR is functionally
identical to any other 1 XMR.
Fungibility is an advantage Monero has over Bitcoin and almost every other cryptocurrency, due to the privacy inherent in the Monero @blockchain and the permanently traceable nature of the Bitcoin blockchain. With Bitcoin, any BTC can be tracked by anyone back to its creation @coinbase-transaction. Therefore, if a coin has been used for an illegal purpose in the past, this history will be contained in the @blockchain in perpetuity. This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies.
Monero has been built specifically to address the problem of traceability
and non-fungibility inherent in other cryptocurrencies. By having
completely private transactions Monero is truly fungible and there can be no
blacklisting of certain XMR, while at the same time providing all the
benefits of a secure, decentralized, permanent blockchain.
