A cryptocurrency is a digital or virtual currency that uses cryptography for security. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.
They use decentralized control as opposed to centralized digital currency and central banking systems. The decentralized control of each cryptocurrency works through a blockchain, which is a public transaction database, functioning as a distributed ledger.
Some of the most popular cryptocurrencies include Bitcoin, Ethereum, Litecoin, and Dogecoin.
They are a new and innovative technology with a lot of potential. However, there are also some risks associated with them. It is important to do your research before investing in cryptocurrencies.
