📖 How Bitcoin Works
Bitcoin is a decentralized digital currency that operates without a central bank or government. Transactions are verified by a network of computers (miners) and recorded on a public ledger called the blockchain.
Think of it like digital gold: it's scarce (only 21 million will ever exist), it's durable (the network has been running since 2009 without downtime), and it's portable (you can send any amount anywhere in the world in minutes).
Every Bitcoin transaction is broadcast to the entire network. Miners compete to validate these transactions by solving complex mathematical puzzles. The first miner to solve the puzzle adds the block of transactions to the blockchain and earns newly minted Bitcoin as a reward.
🔑 Key Concepts
Blockchain
A chain of blocks, each containing transaction records. Once added, data cannot be altered — making it immutable and transparent.
Mining
The process of using computing power to validate transactions and secure the network. Miners are rewarded with new BTC.
Halving
Every ~4 years, the mining reward is cut in half. This reduces new supply and has historically preceded major price increases. The last halving was in April 2024.
Wallets
Software or hardware that stores your Bitcoin private keys. Your keys = your coins. Lose your keys = lose your Bitcoin forever.
💰 Why Does Bitcoin Have Value?
- Scarcity: Only 21 million will ever exist
- Decentralization: No government can print more or shut it down
- Network effect: 200M+ users worldwide
- Institutional adoption: BlackRock, Fidelity, and governments hold BTC
- Inflation hedge: Fixed supply vs. unlimited fiat money printing
📈 Bitcoin's Track Record
Despite extreme volatility, Bitcoin has been the best-performing asset of the last decade. It went from $0 in 2009 to an all-time high above $100,000 in 2024. However, it has also experienced 80%+ drawdowns multiple times.
