"Crypto, short for cryptocurrency, is a digital or virtual currency that uses cryptography for security and is decentralized, meaning it's not controlled by any government or financial institution. Transactions with cryptocurrencies are recorded on a public ledger called a blockchain, and new units are created through a process called mining. Bitcoin is the most well-known cryptocurrency, but there are many others, such as Ethereum, Litecoin, and Monero. Crypto has the potential to revolutionize the way we think about money and financial transactions, but it can also be volatile and risky."
