CMC

CMC is the everyday shorthand for CoinMarketCap, a cryptocurrency data aggregator that tracks prices, trading volume, and market capitalization across thousands of coins and exchanges. Launched in 2013, it became one of the first widely used reference points for sizing up digital assets, and its rankings are still routinely cited in crypto news coverage, exchange marketing, and community discussion.

A coin's CMC rank comes from multiplying its price by its circulating supply, the portion of tokens actually available to the public rather than locked in team wallets, vesting contracts, or treasuries. Verifying that circulating-supply figure is central to the process: project teams submit documentation, and CMC checks it against on-chain data before a coin is treated as fully verified and placed in the ranked tables rather than left unranked. Listings also weigh trading liquidity and the number of supported markets, since thin or inflated volume can distort how large a coin appears.

Beyond the rankings table, CMC provides portfolio tracking, watchlists, price alerts, and educational resources aimed at newcomers. Since 2020 it has operated as a subsidiary of the exchange Binance, a relationship that drew criticism after Binance's own token rose sharply in the exchange rankings CMC publishes. Partly in response to concerns about manipulated figures, CMC has added metrics such as a liquidity score meant to flag exchanges reporting unrealistic volume. The data remains a common industry reference, but experienced traders still cross-check numbers across more than one tracker rather than treating any single source as definitive.
