All cryptocurrencies, coins or tokens other than Bitcoin are referred to as Altcoins. The term Altcoin is short for alternative coin. It alludes to the fact that Bitcoin emerged as the first or original cryptocurrency in 2009 and subsequent cryptocurrencies are classified as “alternative” or “alternate” coins.

A prominent example of an altcoin is the second largest cryptocurrency Ethereum.
