History and Evolution
Bitcoin’s journey began in 2008 when the pseudonymous Satoshi Nakamoto published its whitepaper. By January 2009, the Genesis Block was mined, marking the birth of decentralized ledger technology. Early adopters mined BTC for pennies, and by 2010, the infamous "Bitcoin Pizza" transaction (10,000 BTC for two pizzas) highlighted its nascent value.
Over the next decade, Bitcoin achieved milestones:
- 2011: First crossed $1.
- 2013: Surpassed $1,000.
- 2017: Peaked near $20,000.
- 2020–2024: Institutional adoption skyrocketed, with companies like Tesla and MicroStrategy adding BTC to their balance sheets.

How Bitcoin Works
1. Blockchain Basics
Bitcoin runs on a decentralized ledger called a blockchain. Transactions are grouped into blocks and validated by nodes globally.
2. Mining and Consensus
Miners compete to solve cryptographic puzzles (PoW) to add new blocks. Successful miners earn BTC rewards and transaction fees.
3. Transaction Flow
- Initiation: A user creates a transaction via a wallet.
- Broadcast: The transaction is shared across the network.
- Verification: Nodes confirm its validity.
- Confirmation: Miners include it in a block (~10 minutes per block).
Bitcoin vs. Other Cryptocurrencies
| Feature | Bitcoin (BTC) | Ethereum (ETH) | Solana (SOL) |
|--------------|--------------|---------------|-------------|
| Focus | Store of value | Smart contracts | High-speed transactions |
| Consensus | PoW | PoS | PoS |
| Supply | 21M capped | No hard cap | No hard cap |
Bitcoin remains the dominant cryptocurrency due to its security, scarcity, and brand recognition.
