Introduction to Bitcoin
Bitcoin (BTC) is a decentralized digital currency powered by blockchain technology, with a fixed supply cap of 21 million coins. Often dubbed "digital gold," it enables seamless cross-border transactions with low fees, no intermediaries, and pseudonymous privacy. As of 2024, Bitcoin trades around $30,000 per coin and is accepted by regulated exchanges globally.
Key Features of Bitcoin
- Decentralization: No central authority controls Bitcoin.
- Scarcity: Capped supply mimics precious metals like gold.
- Global Accessibility: Transact 24/7 without traditional banking barriers.
How Bitcoin Enters Circulation: The Mining Process
Unlike fiat currencies, Bitcoin isn’t issued by governments. Instead, it’s "mined" through a computational process:
- Miners compete to solve complex cryptographic puzzles using specialized hardware.
- Successful miners validate transactions and add them to the blockchain, earning newly minted BTC as a reward.
- Block Rewards Halve every 210,000 blocks (≈4 years), reducing new supply—a mechanism designed to combat inflation.

Why Mining Matters
- Secures the network against fraud (e.g., double-spending).
- Incentivizes participation without centralized control.
