Bitcoin Explained in 5 Minutes: The Beginner's Complete Overview

What Is Bitcoin? Bitcoin is digital currency that exists only on the internet. Unlike dollars, no government or bank controls it. Created in 2009 by the pseudonymous Satoshi Nakamoto, it is often described as digital gold — scarce, decentralized, and not controlled by any single authority.

How Does Bitcoin Work? Bitcoin runs on blockchain technology:

• The Blockchain: A public ledger recording every Bitcoin transaction ever made • Decentralized: Copied across thousands of computers worldwide — no single point of failure • Immutable: Once recorded, transactions cannot be altered • Transparent: Anyone can view all transactions (wallets are pseudonymous)

Who Verifies Transactions? Bitcoin uses a network of "miners" that compete to solve mathematical puzzles. The winner adds the next block and receives a Bitcoin reward. This is called Proof of Work.

Why Only 21 Million Bitcoin? Satoshi programmed a hard cap of 21 million into the code. This scarcity is intentional. Approximately 19.5 million have already been mined. New supply halves every 4 years — an event called the "halving."

What Can You Do With Bitcoin? • Store value as a hedge against currency inflation • Send money internationally without intermediaries • Use as a medium of exchange • Trade on cryptocurrency exchanges

The Real Risks • Volatility: Bitcoin has lost 80%+ of its value multiple times • Regulatory Risk: Governments can restrict or ban crypto use • Security Risk: Lose your private keys and your Bitcoin is gone forever • Scam Risk: The crypto space is full of fraud
