Introduction
Bitcoin (BTC) emerged in 2008 as a revolutionary response to the global financial crisis. Designed to replace physical cash and eliminate reliance on traditional banking intermediaries, it introduced the world to decentralized digital currency.
The Origin of Bitcoin
Bitcoin first appeared in a whitepaper authored by the enigmatic Satoshi Nakamoto—a pseudonym whose true identity remains unknown. The paper outlined:
- A peer-to-peer digital currency system
- The foundational blockchain technology (a public, immutable ledger for recording transactions)
- Key principles of decentralization and cryptographic security

How Bitcoin Functions
1. Decentralized Transactions
Bitcoin enables secure, anonymous, and rapid transactions without third-party oversight. Its volatility, however, has shifted its primary use from everyday purchases to a high-risk investment and digital gold.
2. Mining & Security
- Transactions are validated by miners using powerful computers.
- Each transaction is encrypted and added to the blockchain, ensuring tamper-proof record-keeping.
- Miners earn new Bitcoins as rewards for completing "blocks" (hence blockchain).
3. Halving Mechanism
- The reward for mining halves every 210,000 blocks (approximately every 4 years).
- This event, called "halving," controls inflation and extends Bitcoin’s mining timeline until ~2140.

Q: Why is Bitcoin compared to gold?
A: Due to its scarcity, durability, and role as a store of value, Bitcoin is often termed "digital gold."
Q: How does halving affect Bitcoin’s price?
A: Historically, halvings reduce supply growth, often driving price increases due to heightened scarcity.
