FAQ about CoinMarketCap
What exactly is CoinMarketCap and what does it do?
CoinMarketCap is a cryptocurrency data aggregator that tracks and displays real-time information about thousands of digital assets across hundreds of exchanges worldwide. The platform collects data on cryptocurrency prices, market capitalizations, trading volumes, and other metrics, then standardizes this information using proprietary methodologies to provide users with accurate market intelligence. Beyond basic price tracking, CoinMarketCap offers tools like portfolio tracking, cryptocurrency comparison, historical data analysis, educational resources, and developer APIs. Since its founding in 2013, it has become the most referenced source of cryptocurrency market data in the industry.
Is CoinMarketCap data reliable?
CoinMarketCap strives to provide reliable data through various verification methods and calculation methodologies. The platform has evolved its approach over time, implementing features like adjusted volume calculations, liquidity metrics, and exchange verification to improve accuracy. While CoinMarketCap is generally considered the industry standard for cryptocurrency data, users should understand that the volatile and sometimes opaque nature of cryptocurrency markets can present challenges for any data provider. The platform is transparent about its methodology and makes updates when necessary to maintain data integrity. For critical investment decisions, many professionals use CoinMarketCap alongside other data sources.
How does CoinMarketCap make money?
CoinMarketCap generates revenue through several channels including premium subscriptions (CoinMarketCap Pro), paid API access tiers, featured listings, advertising placements, and partnership programs. The platform offers various subscription levels for both individual and institutional users that provide advanced features, enhanced API access, and additional data. Since being acquired by Binance in 2020, CoinMarketCap operates with the financial backing of the world's largest cryptocurrency exchange while maintaining editorial independence in its data presentation. The core price-tracking functionality remains free to users, following the platform's mission to democratize access to cryptocurrency market data.
How do I use the CoinMarketCap API?
To use the CoinMarketCap API, you first need to create an account on the platform and register for an API key. The platform offers multiple tiers of API access, from a basic free plan with limited call volume to premium options with higher rate limits and additional endpoints. After obtaining your key, you can make HTTP requests to various endpoints to retrieve cryptocurrency data, including latest listings, historical data, metadata, and exchange information. The CoinMarketCap developer portal provides comprehensive documentation including endpoint descriptions, authentication methods, response formats, error handling, and code examples in various programming languages to facilitate integration.
Why might prices differ between CoinMarketCap and exchanges?
Price differences between CoinMarketCap and specific exchanges occur because CoinMarketCap calculates a volume-weighted average price across multiple exchanges, while individual exchanges display prices based solely on their own trading activity. This discrepancy, known as the "spread," is normal in financial markets. Various factors contribute to these differences, including regional price premiums in certain markets, liquidity variations between exchanges, arbitrage opportunities not yet exploited, withdrawal/deposit restrictions affecting price equilibrium, and the time lag required for CoinMarketCap to aggregate and update its data. CoinMarketCap's methodology aims to provide the most representative global average price rather than mirroring any single exchange.
How does the CoinMarketCap ranking system work?
CoinMarketCap primarily ranks cryptocurrencies by market capitalization, calculated by multiplying the current price by the circulating supply of tokens. This methodology prioritizes the total economic value rather than just price, providing a more meaningful comparison between cryptocurrencies with different supply characteristics. Over time, CoinMarketCap has refined its ranking system to include additional factors such as liquidity metrics, verified exchange volume, and project activity. The platform clearly documents its methodology and requirements for listing. Users can also sort cryptocurrencies by other metrics including price, volume, recently added, and percentage change, allowing for alternative perspectives on market performance.
What features does the CoinMarketCap app offer?
The CoinMarketCap app, available for both iOS and Android devices, offers most of the functionality of the website in a mobile-optimized format. Key features include real-time cryptocurrency price tracking, customizable watchlists for monitoring selected assets, portfolio tracking with performance metrics, price alerts for specific thresholds, cryptocurrency news and updates, educational content through CMC Alexandria, and home screen widgets for quick information access. The app synchronizes with user accounts, allowing seamless transition between desktop and mobile experiences.

How often is data updated on CoinMarketCap?
CoinMarketCap updates price, volume, and market capitalization data approximately every 1-5 minutes, depending on the specific cryptocurrency and data point. High-market-cap cryptocurrencies and those with significant trading volume generally receive more frequent updates. Global market statistics, cryptocurrency rankings, and exchange information are recalculated with each data refresh. Historical data points are recorded at regular intervals and maintained indefinitely, allowing for long-term trend analysis. The platform's API provides access to both current and historical data with various update frequencies depending on the subscription tier. For time-sensitive trading decisions, users should be aware of the potential slight delay inherent in any data aggregation service.
