Bitcoin is a peer-to-peer system for transferring value without a central transaction processor. Its public ledger lets participants verify transactions and the rules governing issuance.
The network and the asset
Bitcoin refers to both a network and its native asset, BTC. A wallet manages keys that can authorise transactions; it does not hold coins like files on a device. Losing access to those keys can mean losing access to funds.
Why supply matters
Bitcoin’s issuance schedule is defined by its consensus rules. Miner rewards decline at scheduled block intervals. This is different from a guarantee that demand or the market price will rise.

Learn how addresses, transaction fees, confirmations, and self-custody work before moving funds. Begin with official documentation and practise with small amounts where appropriate.
