What Bitcoin (BTC) is

Bitcoin is a decentralized digital currency launched in 2009 by the pseudonymous Satoshi Nakamoto.

It runs on a blockchain (a public, tamper-resistant ledger).

No central bank, no government control — transactions are peer-to-peer.

Why people care about BTC

Scarcity: Only 21 million BTC will ever exist.

Store of value: Often compared to “digital gold.”

Censorship-resistant: Hard to freeze or block transactions.

Global & permissionless: Anyone can use it with an internet connection.

How it works (simple version)

Transactions are verified by miners using proof-of-work.

Miners bundle transactions into blocks and secure the network.

New BTC is issued as mining rewards (this reward halves roughly every 4 years — the halving).

Common uses

Long-term investment / hedge

Trading & speculation

International transfers

Protection against inflation (especially in some countries)

Risks to know

Volatility: Prices swing a lot.

Regulation uncertainty

Self-custody risk: Lose your keys = lose your BTC.
