cryptocurrency
A digital currency designed to work through a computer network that is not reliant on any central authority.
Due to the nature of their value being based heavily a speculation, cryptocurrencies have very unstable exchange rates. This speculative nature and less regulatory oversight has resulted in them being tied with many get-rich-quick schemes, money laundering, and scams. Memecoins, a category of cryptocurrencies that are predominately based on internet memes and jokes, tend to be some of the most volatile and prone to scams out of cryptocurrencies.
