🌐 What is Cryptocurrency?
Cryptocurrency is a type of digital or virtual money that uses cryptography (secure coding) to secure transactions. Unlike traditional currencies such as the dollar or euro, most cryptocurrencies are decentralized — meaning they are not controlled by any government or central bank.
The most well-known cryptocurrency is Bitcoin (BTC), but there are thousands of others, including:
Ethereum (ETH)
Binance Coin (BNB)
Solana (SOL)
Ripple (XRP)
Cardano (ADA)

🔗 How Does It Work?
Most cryptocurrencies run on blockchain technology — a public, decentralized ledger that records every transaction. Think of it as a giant digital notebook that everyone can see but no one can easily change.
Key concepts:
Wallets: Store your crypto securely. Can be hot (online) or cold (offline).
Private Keys: A secret code that lets you access your wallet and make transactions.
Mining/Staking: Ways of validating transactions and earning rewards.
