Cryptocurrency may sound like a complicated idea, but at its core, it's simply digital money that works differently from the traditional currency you use every day. Instead of being printed by governments or controlled by banks, cryptocurrency operates online, is powered by technology, and is secured through cryptography. Let's break it down into simple parts so you can understand exactly what cryptocurrency is, how it works, and why so many people are talking about it. 1.1 The Meaning of Cryptocurrency The word "crypto" comes from "cryptography," which means secret writing or codes. In the world of cryptocurrency, cryptography is used to secure transactions, protect information, and control the creation of new coins. Cryptocurrency is: Digital: You can't touch it or hold it like cash.Decentralized: It's not controlled by any one government, bank, or company.Encrypted: Transactions and user data are protected using complex codes.Peer-to-peer: You can send money directly to someone without needing a bank or SSpayment app.So when someone says "cryptocurrency," they're really talking about a type of money that lives entirely online, uses technology to stay secure, and allows people to trade, save, and spend without needing a middleman like a bank.
