About Bitcoin (BTC)
What Is Bitcoin (BTC)?
Bitcoin is an open-source peer-to-peer monetary network. BTC is its native asset. The network lets users transfer value without a bank controlling the ledger. Transactions are recorded on a public blockchain and validated under rules enforced by Bitcoin nodes.
How Does Bitcoin Work and What Is BTC Used For?
Miners group transactions into blocks and compete through proof of work. Full nodes independently reject invalid blocks. BTC is used for transfers, savings, collateral, and settlement. New bitcoin enters circulation as block rewards. The reward halves on a fixed schedule until issuance approaches the hard cap of 21 million BTC.
Bitcoin Security, Control and Risks
Bitcoin has no token contract. Security comes from proof of work, economic incentives, cryptography, and broad node verification. Risks include price volatility, lost keys, exchange custody, mining concentration, fee spikes, and regulatory restrictions. Transactions are normally irreversible.
