Crypto, or cryptocurrency, is a digital asset that leverages blockchain technology to record transactions transparently and in a decentralized manner without the need for intermediaries like banks. The most well-known examples are Bitcoin and Ethereum, which are not only used as means of exchange but also as investments and as the foundation for various innovations such as smart contracts.
