Overview
CoinGecko is a freemium cryptocurrency analytics tool that tracks prices, market capitalization, trading volume, and other market data for a wide range of digital assets. It provides portfolio tracking, price alerts, and education content. CoinGecko is one of the two dominant market data aggregators, alongside CoinMarketCap.
How It Works
CoinGecko collects price and volume data from hundreds of exchanges and aggregates them into global market statistics. It ranks assets by market capitalization, tracks derivatives and DeFi data, and publishes trust scores that rate exchanges by liquidity and operational transparency. Users can follow assets, build portfolios, and access an API with tiered limits.
Why It Matters
CoinGecko is a primary reference for the market data layer of crypto, used by individuals, media, and applications. Its trust-score methodology and free education content added credibility to an industry that often lacked it. Its data, however, is exchange-reported and can be manipulated, so it is a starting point rather than a complete picture of market truth.
