Bitcoin (BTC) is a decentralized cryptocurrency launched in 2008 as an alternative to traditional financial systems. Designed by the pseudonymous Satoshi Nakamoto, it introduced blockchain technology—a public ledger recording all transactions without intermediaries like banks.
Key Features of Bitcoin
✅ Decentralization: Operates on a peer-to-peer network with no central authority.
✅ Fixed Supply: Capped at 21 million coins, ensuring scarcity.
✅ Security: Uses cryptographic proof to validate transactions.
✅ Transparency: All transactions are publicly verifiable on the blockchain.
✅ Low Fees: Cross-border transfers cost less than traditional methods.

How Bitcoin Works
1. Mining and Supply
- New BTC is created through mining, where miners solve complex puzzles to add blocks to the blockchain.
- Rewards halve every 210,000 blocks (≈4 years). The 2024 reward is 3.125 BTC per block.
- Final BTC will be mined around 2140.
2. Wallets and Transactions
- Users store BTC in digital wallets (hot/cold storage).
- Each transaction is signed with a private key for security.
3. Consensus Mechanism
- Bitcoin uses Proof-of-Work (PoW) to prevent double-spending.
