Introduction
Bitcoin, the world's largest cryptocurrency by market capitalization, experienced a sharp 12% price drop within 24 hours, reaching a 3-week low. This volatility follows Tesla CEO Elon Musk’s announcement that Tesla would no longer accept Bitcoin as payment for its vehicles.
For newcomers, understanding Bitcoin’s fundamentals is crucial before diving into investments. Below, we break down what Bitcoin is, how it works, and key considerations for investors.
What Is Bitcoin?
Bitcoin (BTC) is a fully digital currency created in January 2009 by an anonymous individual or group under the pseudonym Satoshi Nakamoto. It operates without central authority—no government or bank controls it.
Key Characteristics:
- Decentralized: No single entity governs Bitcoin.
- Limited Supply: Only 21 million Bitcoins will ever exist, creating scarcity.
- Pseudonymous: Transactions are public, but identities are encrypted.

How Does Bitcoin Work?
1. Digital Wallets
Bitcoins exist as computer files stored in a digital wallet (software or hardware). Wallets have:
- A public key (like an account number for receiving BTC).
- A private key (a secret code to authorize transactions).
2. Blockchain Technology
Every transaction is recorded on the blockchain, a public ledger. This ensures:
- Transparency: All transactions are traceable.
- Security: Prevents double-spending or fraud.
3. Mining
New Bitcoins enter circulation through mining, where powerful computers solve complex math problems to validate transactions. Miners earn BTC as rewards.
Bitcoin’s Volatility: A Snapshot
- 2021 Performance: Bitcoin hit an all-time high of ~$65,000 in April 2021, delivering a 76.61% annual return.
- Recent Drop: The 12% plunge highlights its sensitivity to market sentiment (e.g., regulatory news or corporate decisions like Tesla’s).
FAQs About Bitcoin
1. Is Bitcoin legal?
Yes, but regulations vary. Some countries ban it, while others treat it as property (e.g., the U.S. IRS taxes BTC holdings).
2. Can Bitcoin replace traditional money?
Partially. While BTC is accepted by some merchants, adoption remains limited compared to fiat currencies.
3. How do I start investing in Bitcoin?
