The term crypto token refers to a special virtual currency token or how cryptocurrencies are denominated. These tokens represent fungible and tradable assets or utilities that reside on their own blockchains. Crypto tokens are often used to fundraise for crowd sales, but they can also serve as a substitute for other things.

A non-fungible token is a unique and non-interchangeable unit of data stored on a blockchain, a form of digital ledger. NFTs can be associated with reproducible digital files such as photos, videos, and audio.
