Cryptocurrency (or crypto) is a type of digital or virtual money that uses cryptography for security and operates on blockchain technology—a decentralized network of computers rather than a central authority like a bank or government.

🔑 Key Features of Crypto:

Decentralized: No single authority controls it; instead, it's run by a network of users.

Secure: Uses encryption to protect transactions and user identities.

Transparent: Transactions are recorded on a public ledger (blockchain) that anyone can view.

Limited Supply: Most have a cap (e.g., only 21 million Bitcoins can ever exist).

Borderless: Can be sent anywhere in the world without banks or exchange rates.

💰 Examples of Cryptocurrencies:

Bitcoin (BTC) – The first and most well-known.

Ethereum (ETH) – Allows smart contracts and decentralized apps (dApps).

Solana (SOL), Cardano (ADA), XRP, and many others serve different purposes.
