Bitcoin's price is set by supply and demand on the exchanges where it trades; no company, government or central bank sets it. Supply follows fixed rules: at most 21 million bitcoin, with new issuance halved about every four years. Demand shifts with adoption, interest rates, regulation and sentiment, so the price changes constantly.

Who decides what a bitcoin costs? No company, government or central bank does. Bitcoin’s price is the price at which buyers and sellers agree to trade, and it changes every time they do. If you are new to the coin itself, start with what Bitcoin is and how it works.
This guide explains how supply and demand set that price, what moves them, why prices differ between exchanges and why no one can tell you where the price goes next. To convert any amount between bitcoin and your currency at a market reference rate, use the Bitcoin calculator.
Who sets the price of Bitcoin?
No one sets it. Bitcoin’s price is the latest price at which a buyer and a seller agreed to swap bitcoin for money.
On an exchange, buyers post bids (the most they will pay) and sellers post asks (the least they will accept). When a bid meets an ask, a trade happens and becomes the latest price. If more people want to buy than sell, buyers bid higher and the price rises. If sellers outnumber buyers, they accept less and the price falls.
The US Commodity Futures Trading Commission (CFTC) says the value of virtual currencies comes from market forces of supply and demand, and that no government or central bank backs them. Bitcoin also has no earnings to anchor its value, and it trades every day, around the clock.
How does Bitcoin’s fixed supply affect its price?
Bitcoin’s supply follows rules written into its software, not demand. No more than 21 million bitcoin can ever exist, and new coins are released on a fixed schedule as rewards to the miners who add new blocks to the blockchain.
As of 28 September 2026, about 20.09 million bitcoin existed, roughly 96% of the limit (Coin Metrics data). Because supply cannot grow when more people want bitcoin, changes in demand show up in the price. The price multiplied by the coins in existence gives bitcoin’s market cap.
It works in reverse too: when demand falls, nothing removes coins to support the price. Since 2017, bitcoin’s daily closing price has fallen more than 50% from a peak at least four times, most recently between October 2025 and June 2026 (Coin Metrics data, as of September 2026). Past performance does not predict future results.
How does the halving affect supply?
The halving cuts the reward for each new block in half every 210,000 blocks, which takes about four years. It slows the creation of new bitcoin. It does not change the 21 million limit or the coins that already exist.
| Halving | Block | Reward per new block |
|---|---|---|
| 28 November 2012 | 210,000 | 50 BTC to 25 BTC |
| 9 July 2016 | 420,000 | 25 BTC to 12.5 BTC |
| 11 May 2020 | 630,000 | 12.5 BTC to 6.25 BTC |
| 20 April 2024 | 840,000 | 6.25 BTC to 3.125 BTC |
At the target pace of one block every 10 minutes, the current reward of 3.125 BTC adds about 450 new bitcoin a day. The next halving is due at block 1,050,000, which at that pace falls in 2028.
Whether halvings move the price is debated: each is known years in advance and comes alongside other changes in demand. Read the history of past Bitcoin halvings. Past performance does not predict future results.
What moves demand for Bitcoin?
Demand depends on who can buy bitcoin, why they want it and how much risk they will take. Besides regulation and the economy, covered in the next two sections, the main drivers are:
- Access and adoption. New ways to buy or hold bitcoin can bring in new buyers. On 10 January 2024, the US Securities and Exchange Commission (SEC) approved spot bitcoin exchange-traded products (ETPs), which investors can buy through an ordinary brokerage account. The SEC said it did not approve or endorse bitcoin itself. Read about Bitcoin adoption and Bitcoin ETFs compared with owning bitcoin.
- Sentiment. News, social media, hacks and company failures can change the mood of the market within hours. Some traders follow that mood with the Crypto Fear and Greed Index.
How do regulation and the wider economy affect Bitcoin’s price?
They change who can buy bitcoin and how much risk investors want to take. The effect is real, but it is not fixed and it cannot be timed.
Regulation. Rules that make buying easier can widen demand, as spot bitcoin ETPs did in the US in 2024. Bans, restrictions or enforcement action in a large market can shrink it.
The wider economy. Inflation, currency crises and conflicts lead some people to buy bitcoin and others to sell risky assets. A 2023 working paper from the International Monetary Fund (IMF) found that US monetary policy affects the crypto cycle much as it affects stocks, in contrast with claims that crypto protects against market risk.
The link with stocks also shifts. On our calculation from daily closing prices, the correlation between the daily moves of bitcoin and the S&P 500 was about 0.0 in 2017 to 2019, 0.6 in 2022, 0.2 in 2023 and 0.5 in the 12 months to 25 September 2026, where 1 means moving in perfect step. An IMF note found a similar rise after early 2020.
Do interest rates affect Bitcoin’s price?
They can. Higher interest rates make cash and bonds pay more and make borrowing dearer, which tends to reduce appetite for risky assets such as bitcoin. Central banks move rates mainly to control inflation.
2022 is the clearest recent example. The US Federal Reserve raised its target range for the federal funds rate seven times that year, from 0-0.25% to 4.25-4.50%. Over the same year, bitcoin’s closing price fell about 64%, from about $46,360 to about $16,520, and the S&P 500 fell about 19% (Coin Metrics and Cboe data).
Rates were not the only cause: in May 2022 the TerraUSD (UST) stablecoin lost its peg to the US dollar and fell close to zero. The IMF paper also found that crypto prices reacted more strongly to US monetary policy after 2020. The link varies, and markets often move before an expected decision, so this says nothing about the next rate change. Past performance does not predict future results.
Why is Bitcoin’s price so volatile?
Because demand can change quickly while supply cannot respond. Bitcoin trades nonstop, has no earnings to anchor its value and reacts fast to news. Traders using borrowed money can also be forced to sell in a fall, which deepens it. Learn how this is measured in the guide to crypto volatility.
You cannot remove that risk, but you can limit it. Buying a fixed amount on a regular schedule, known as dollar-cost averaging, spreads your purchases over time. It smooths your average price but does not prevent losses.
Why do exchanges show different Bitcoin prices?
Because each exchange has its own buyers, sellers and costs. Prices on large exchanges usually stay close, but they rarely match exactly.
- Separate order books. Each exchange matches its own buyers and sellers, so its latest trade can differ from another exchange’s.
- Liquidity. On quieter exchanges, one large order can move the price. See what liquidity means for bitcoin.
- Currency pair. Bitcoin priced in euros is a separate market from bitcoin priced in US dollars. See how crypto trading pairs work.
- Spreads and fees. Some services build a margin into the price they show. Others show the market rate and charge a separate fee.
When prices drift apart, traders buy where bitcoin is cheaper and sell where it is dearer, which pulls prices back together. Benchmarks blend several exchanges: the CME CF Bitcoin Reference Rate is a once-a-day price built from trades on several major exchanges.
Coinmama’s calculators show market reference rates, which do not include fees. Latest reference price: 1 BTC =$77,365.30-4.10% (24h). Past performance does not predict future results.
Why is the price I pay different from the market price?
Because a purchase includes costs that a market price leaves out. Depending on the service, these can include a spread (a buy price set above the market rate), a service fee, a payment-method fee and, when coins are sent to a wallet, a network fee.
Treat the rate on a chart or calculator as a guide, not a quote. Before you confirm any purchase, check the total cost and the amount of bitcoin you will receive.
Can anyone predict Bitcoin’s price?
No. No one can reliably predict bitcoin’s price, whether for tomorrow or for years ahead. The forecasts you see online are opinions built on assumptions.
Forecasts differ so much because they rest on different guesses about new buyers, interest rates, rules and market mood. With no earnings to value, there is no agreed fair price for a model to aim at. For the downside case, read whether bitcoin could crash to zero.
Be wary of confident price targets, especially ones that come with a sales pitch. The CFTC’s advice is direct: if someone tells you there is no risk of losing money, do not invest. Past performance does not predict future results. If you decide to buy, see the Bitcoin price and payment options.
