Frequently asked questions

An exchange reports its own volume and nobody audits it. That reported figure is shown on every exchange and market, but only the volume of markets that pass the published checks is added to a coin's and the market's total. Other trackers either add everything or scale it down by a formula they do not publish. The checks are described in Metrics explained.

Rank follows market cap, and market cap is price times circulating supply. Supply figures differ between sources. Each one here says how it is known (measured, reported, entered, derived, estimated); coins with a known circulating supply rank before those with only an estimate, and units an issuer holds itself are not counted as circulating. See Supply and market cap.

The Coinsprey price is a volume-weighted average over all markets that count, not the price of any one exchange. Every market that made it, and every market that was left out with the reason, is listed on the coin's page. Against the largest trackers the typical difference is about a tenth of a percent on large coins.

How well the price is supported: on how many exchanges it rests, how closely they agree, how deep their order books are, how fresh the data is. It is always shown with its seven parts. It says nothing about the coin as a project or as an investment.

A coin appears when it trades on an exchange that is read. Two different coins often share a ticker; they are listed apart, each under its ticker and its name. A market is matched to a coin by what the exchange itself calls the asset and by its price, never by the ticker alone.

Exchanges' tickers are read once a minute, and each price says how old the data behind it is. Order books and public trades are read in rounds, market by market. Exchanges are weighed once an hour.

Its markets are listed with everything it reports, but they do not enter a coin's price while an exchange that passes the checks trades that coin. An exchange is counted when its order books can be read, its prices agree with the rest of the market and its data arrives reliably. A newly added exchange starts as not counted and changes sides only after six hours of measurements in a row.

No. It means a measurement of public data does not fit what the exchange reports, stated with its own figures. There can be innocent explanations, and Red flags explained lists them for each flag. Documented cases are kept apart under Fraud Signals, each with a link to its evidence.

No. It is computed only from an exchange's public market data: spreads, depth, how its prices compare with others, how reliably its API answers. It says nothing about custody, solvency, licences or who runs the exchange, because none of that can be measured from market data.

There is no fee and no application. An exchange can be read when it has a public API with a list of all its markets; a public order book and recent trades per market are what lets its volume be checked. An exchange that only passes on another exchange's markets is listed with a label saying so, and its volume is counted once, under the other exchange.

Every figure is computed by published rules from the exchange's own public data, so the first step is to compare it with what the public API returns: the measurements are on the exchange's page. A mistake on this side is corrected for everybody and noted in the methodology. Nothing can be changed for one exchange by request or for payment. A mistake can be reported through the form on Fraud Signals.

Automatically, when it starts trading on an exchange that is read. There is no listing fee and no form. Its name, logo and links come from the exchanges that trade it, from its token contract and from public token lists.

The circulating supply is not known, so the market cap is an estimate from the total supply read from the token contract. Such coins rank after those with a known supply and are left out of the market's total market cap.

None of its markets traded in the last 24 hours, so it has no price now and no rank. It stays listed for 30 days with its last price and the date of it.

A tokenized stock or fund follows the price of something that is not crypto, so it has a list of its own and is not part of the crypto totals. A wrapped or staked token is a copy of a coin that is already counted, so it keeps its price and rank but is left out of the total market cap.

No. No exchange and no project can pay for a position, a better figure, a listing or the removal of a flag. Advertising is sold directly, is marked as such, is the same for every visitor and never appears inside rankings or prices.

No cookies are set and no analytics or advertising scripts of other companies are loaded, so there is no consent banner either. Visits are counted as daily totals only, without a record of any single visitor. Details are on the privacy page.

No. The site publishes market data and how it was obtained. Nothing on it is a recommendation to buy, sell or hold anything; see the disclaimer.

Yes. The data can be read, quoted and linked, with Coinsprey named as the source, and a free API serves the same figures within a rate limit. The rules are in the terms of use.

Through the form at the bottom of Fraud Signals, with a link to what shows the mistake. A report is read by an editor and published nowhere as written; a confirmed mistake in a rule is corrected for everybody.
