Introduction to Crypto

Cryptocurrency, or crypto, is a form of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (fiat money), cryptocurrencies are decentralized and typically operate on blockchain technology, which is a distributed ledger enforced by a network of computers (nodes). The primary purpose of cryptocurrencies is to enable secure, anonymous transactions without the need for a central authority. Bitcoin, created in 2009 by an unknown person or group of people using the name Satoshi Nakamoto, was the first decentralized cryptocurrency. Since then, thousands of alternative cryptocurrencies have been created, such as Ethereum, Ripple, Litecoin, and many others.
