It is possible to peg cryptocurrencies to underlying assets including U.S. dollars, central bank digital currencies, privacy coins (senders and receivers are anonymous), governance tokens (owners can vote on future blockchain development), utility tokens, and non-fungible tokens (distinct characteristics from others). I am coming from the developer/development side of things. There are also investors and speculators hoping for appreciation. Whether you own or are considering owning cryptocurrency, it is very important that you understand its purpose and functionality.
