Follow a live BTC/USD reference, inspect the historical path, compare real dollar venues, and learn what the number can—and cannot—tell you.
There is no official global Bitcoin price. The number below is a median reference built from available BTC/USD observations at established exchanges.
Median of available public BTC/USD observations from Coinbase Exchange, Kraken and Bitstamp.
The figures below recalculate whenever you change the chart window.
The headline reference uses the median of the available USD observations below.
The chart uses historical close prices from public BTC/USD candles. A separate live reference point refreshes every 30 seconds from the three-venue USD median.
BTC/USDT remains separately labelled throughout Bitcoin.now and never enters the headline BTC/USD reference as though the quote assets were identical.
Bitcoin.now does not accept trades or connect exchange accounts. Its guides explain costs, custody and risk without placing an order.
Read the informational buying guide →Bitcoin’s network validates ownership and supply. Markets separately decide the latest exchange price.
Buyers post bids and sellers post asks. A market order accepts the best available prices instead of choosing one fixed price for the whole world.
When compatible orders meet, a trade prints. The latest trade can be tiny, so “last price” does not show how much liquidity exists nearby.
Exchanges have different customers, currencies, fees and order books. Arbitrage can narrow a gap, but it cannot make every venue identical at every moment.
Bitcoin.now takes the median of available real BTC/USD markets. A median reduces dependence on one unusual venue without creating an official price.
If only two eligible venues are available, the median is the midpoint between them. BTC/USDT is displayed elsewhere under its actual quote asset and does not substitute for a missing dollar venue.
Price becomes more useful when it is not asked to do the job of supply, liquidity, volume, or ownership.
Switch to the five-year range to see qualifying markers. Dates add context; they do not prove causation.
A scheduled subsidy change enforced by validating nodes. The date is known after the halving block is mined; later market moves can have many causes.

A network rule or capability reached activation. Protocol adoption and market price are separate measurements.

A market-access event that changed available products or participants without changing Bitcoin’s consensus supply rules.

A price rises when aggressive buying consumes available asks faster than sellers replace them. It falls when selling consumes bids. The same dollar flow can produce a different move when order-book depth changes.
Thin markets can move sharply. Borrowed positions may be liquidated when collateral falls below a venue’s rules, creating forced orders. A price chart cannot reveal every leveraged position.
Banking access, exchange availability, ETF flows, custody failures, regulation, taxes, and software incidents can change who can act and how quickly. Timing alone does not prove which factor caused a move.
“Bitcoin went up” is incomplete. State BTC/USD or BTC/USDT, the source, and the selected time window. A five-minute candle answers a different question from a weekly close.
A dollar move grows less informative as the price level changes. Percentage return and drawdown make periods easier to compare, but the starting date still changes the result.
A correct chart does not protect a seed phrase or prove an exchange is solvent. Read the Bitcoin wallet guide and self-custody guide before treating market access as ownership.
The headline BTC/USD number is a read-only reference. Public venue observations are retrieved through maintained CCXT exchange adapters. Coinbase Exchange, Kraken and Bitstamp are eligible components when their actual BTC/USD markets respond.
The median limits the influence of one unusual last trade. Historical candles come from one labelled public venue at a time, so the live reference and the last historical close may differ. Data can be delayed, unavailable, revised by a venue, or affected by network and rate limits.
Short answers to the points readers most often mix together.
No central party sets one official price. Each venue matches its own orders. Bitcoin.now combines eligible BTC/USD observations into a labelled reference.
No. USD is a fiat currency. USDT is a dollar-targeting token issued by Tether. The markets can trade close together, but their quote assets and risks are different.
They can have different sources and timestamps. The candle records a completed interval at one venue, while the live point is the current multi-venue reference.
Most Bitcoin spot markets operate around the clock. Liquidity, spreads, maintenance, and available payment rails can still change by venue and time.
No. Historical prices show completed observations under past conditions and do not establish a future result.
A useful price reading keeps the market, time, source, and comparison question attached. These checks turn a moving line into a record another reader can understand.
BTC/USD describes bitcoin quoted in U.S. dollars. A BTC/USDT observation can be close, but its quote asset is a privately issued token rather than cash dollars.
The first and last close produce a return, but the path between them shows the risk a holder experienced. Highs, lows, drawdowns, and event markers explain that path.
