One asset, many order books
Bitcoin trades on hundreds of venues at once, each with its own order book: a live list of bids (what buyers offer) and asks (what sellers want). The Bitcoin price on a venue is simply the last price at which a bid and an ask met there. Between that last trade and the next one, the "price" is really two numbers — the best bid and the best ask — separated by the spread.
Because there is no opening bell and no close, this happens 24 hours a day, every day of the year. The Bitcoin price never settles; it only keeps trading.
From many books to one number
Since every venue has its own last trade, there are as many Bitcoin prices as there are order books. Index providers average across venues to publish a single reference number; each does it differently, which is why two websites rarely show the exact same Bitcoin price at the same second.
The BIKENZO terminal takes a different route: it uses BTC/USD from one real exchange order book, with daily history back to August 2011. The number you see is one that actually traded — not a blend whose recipe sits in someone else’s spreadsheet.
Why the Bitcoin price differs between exchanges
Venues differ in liquidity, fees, banking rails and local demand, so their Bitcoin prices drift slightly apart. Occasionally the gap becomes famous — South Korean exchanges traded at a persistent premium in 2017, the so-called kimchi premium — but arbitrage usually keeps the differences to fractions of a percent: whenever the gap exceeds the cost of closing it, traders buy on the cheap venue and sell on the expensive one until it narrows.
For reading charts, the lesson is consistency: compare a Bitcoin price only with history from the same source, because each venue’s quirks are baked into its own series.
The Bitcoin price in other currencies
A Bitcoin price in euros, yen or pounds comes about in one of two ways. Liquid pairs like BTC/EUR trade directly on their own order books. For most currencies, though, the quoted number is a conversion: the BTC/USD price multiplied by a foreign-exchange rate.
That is exactly how our live overview computes the Bitcoin price in some thirty currencies: one real BTC/USD trade, converted at the ECB’s official reference rates. A converted number is honest as a reference — but it is not a quote you could trade at, and a serious site says so.
What this means for reading any chart
Once you know the machinery, three habits follow. Check the source: a Bitcoin price without a stated origin is a rumour with digits. Mind the pair: BTC/USD and a converted BTC/EUR can tell slightly different stories when the dollar itself moves. And compare changes, not just levels — which is precisely how the BIKENZO terminal plots liquidity against the Bitcoin price. None of this tells you where the price goes next; it tells you what the number in front of you actually is.
