Price data source
Prices come from the public CoinGecko API and refresh roughly every 2 minutes via your browser cache. Actual execution prices on individual exchanges may differ slightly from what's shown here due to liquidity and spread.
What is Bitcoin?
Bitcoin (BTC) is the first cryptocurrency, created in 2009 by a developer (or group) known by the pseudonym Satoshi Nakamoto. Transactions are recorded on a decentralized ledger called a blockchain, without any central bank or government, and the total supply is capped at 21 million coins, released gradually through mining.
How is the price determined?
Bitcoin has no official, centrally set price. It's a market price formed in real time by buy and sell orders across many exchanges worldwide, and this page shows a reference average price aggregated across exchanges. It trades 24 hours a day with relatively thin volume, so it tends to be far more volatile than stocks or foreign exchange.
Investment note
This page is a reference resource providing price information and does not constitute investment advice or recommend any particular timing. Cryptocurrencies carry very high price volatility and risk of loss, and in many jurisdictions they are not classified as regulated financial products, so they may not carry deposit-insurance-style protections. Please make your own careful, informed investment decisions.
Frequently Asked Questions
Why does Bitcoin's price differ slightly between exchanges?
Bitcoin isn't traded on a single exchange β it trades independently on many exchanges worldwide. Differences in liquidity, volume, and the currencies each exchange supports (USD, EUR, USDT, etc.) can create momentary price gaps or regional premiums between markets. This page shows an average aggregated across multiple exchanges.
Why is Bitcoin's price so volatile?
Compared to stocks or currencies, Bitcoin has a smaller market size (market cap) and trading volume, trades around the clock, and is heavily influenced by regulatory news and large investors' buy/sell activity. It also has no underlying fundamentals like earnings or dividends, so prices can swing sharply based on investor sentiment.
How many bitcoins will ever exist?
Bitcoin's total supply is permanently capped at 21 million coins by its protocol. Mining rewards are cut in half roughly every four years in an event called the halving, and the last bitcoin is expected to be mined around the year 2140.
