Why the same coin shows a different price on every site
There is no single official crypto price. How each venue sets its own, why the gaps exist, and which number your wallet should be using.
Unlike a listed stock, crypto has no central exchange and therefore no single official price. Every trading venue runs its own order book, and the price is whatever buyers and sellers there have most recently agreed.
Where the gaps come from
Liquidity. A venue with few traders moves more on each trade, so its price drifts further from the broad market.
Geography and payment rails. A market where it is hard to get dollars in or out often trades at a premium, because demand cannot easily be arbitraged away.
Timing. Prices move constantly; two sites quoting a second apart will differ slightly for no deeper reason than that.
Fees and spreads. The headline price is the midpoint. What you actually pay includes the spread, which some venues quietly widen instead of charging a visible fee.
Why the gaps stay small, mostly
Traders buy where it is cheap and sell where it is expensive, which closes the gap and is why major venues usually agree to within a fraction of a percent.
Gaps persist only where arbitrage is blocked — capital controls, withdrawal limits, or a venue nobody trusts enough to move size through.
Which number to trust
For valuing a balance, an aggregated market rate is the right reference: it averages across venues and is harder for any single market to distort.
BYCRYPTO converts balances at a live aggregated market rate, refreshed every minute, rather than a number picked internally. If you want to check it, any major market data site will be within a fraction of a percent of what you see.
For an actual trade, the only price that matters is the one on the venue you are trading on, including its spread.
