Introduction

Bitcoin is a revolutionary digital currency created in 2009 by an anonymous individual or group under the pseudonym Satoshi Nakamoto. It operates without a central authority, using blockchain technology to ensure transparency and security.

How Does It Work?

Bitcoin relies on a decentralized network of computers (called nodes) that maintain a public ledger — the blockchain. Every Bitcoin transaction is verified by these nodes through a process called mining.

Key Features

• Decentralized: No central bank or government controls it.
• Limited Supply: There will only ever be 21 million Bitcoins.
• Secure & Transparent: All transactions are recorded on a public ledger.
• Global: Bitcoin can be sent anywhere with internet access.

Why Does It Matter?

Bitcoin offers an alternative to traditional financial systems. It's used for investing, transferring value globally, and as a hedge against inflation in some regions.

Conclusion

Whether you're a beginner or a seasoned crypto user, understanding Bitcoin is essential to exploring the broader world of blockchain and decentralized finance (DeFi).
