Key Features
Decentralized & Secure: Runs on a global network of nodes using proof-of-work (mining) to validate transactions and secure the blockchain. No single entity controls it.
Scarcity: Fixed supply of 21 million coins makes it "digital gold" in the eyes of proponents. New bitcoins are issued via mining rewards that halve roughly every 4 years (next halving expected around 2028).
Transparency: All transactions are recorded on a public blockchain (immutable ledger), but users control funds via private keys (pseudonymous).
Divisibility: 1 BTC = 100 million satoshis (sats).
How It Works (Simplified)
Users send BTC using wallet addresses.
Transactions are broadcast to the network.
Miners confirm them in "blocks" (added ~every 10 minutes).
The longest chain of valid blocks forms the blockchain.5d6bdd
History & Significance
Bitcoin emerged during the 2008 financial crisis as an alternative to traditional finance. It has grown from near-zero value to a trillion-dollar asset class, with major institutional adoption (e.g., ETFs, corporate treasuries like MicroStrategy/Strive).18e326
It powers innovation in finance (DeFi, remittances) but faces criticism over energy use (proof-of-work), volatility, and past associations with illicit activity (though most activity is now legitimate).
