What Is CoinGecko and What Can You Do on the Site?

CoinGecko is a cryptocurrency data aggregator that tracks prices, charts, market capitalization, and trading volume across thousands of coins. You can use it to check live market data, spot trending coins and top gainers or losers, follow crypto news, track a portfolio, and access market data through an API. The core site is open to browse, and paid tiers exist for ad-free use and API access.

What data CoinGecko shows

The homepage is built around a market-cap-ranked list of cryptocurrencies. According to the site, it tracks 22,501 cryptocurrencies and displays aggregate figures such as:

Each coin row links to price, charts, and market data. You can change the price-change window (for example 30 days), switch metrics such as fully diluted valuation or market cap/FDV ratio, set rows to 50, 100, or 300, and filter by chain or by quick filters like "On the Move," "Blue Chips," "Growing Projects," "Active Small Caps," and "Recent Breakouts."

What you can do beyond price checking

• Find movers and trends. Dedicated sections list trending coins, top gainers, and top losers. The site also highlights which categories are leading, such as options and prediction-market coins in the sample data.
• Track a portfolio. The site offers portfolio creation and tracking, with real-time updates and push notifications through its app.
• Read market context. A news and market-insight section summarizes events such as options expiries, Fed decisions, and large funding rounds, with timestamps.
• Explore categories and chains. You can browse coins grouped by narrative category or by blockchain, from large networks like Ethereum and Solana to smaller chains.
• Pull data programmatically. CoinGecko offers an API with its own pricing page, which matters if you plan to build dashboards or automate data collection.

How coins are ranked and listed

CoinGecko explains its methodology on the site: coins are ranked primarily by market capitalization, which is calculated as price multiplied by circulating supply. This is why the default view is "Cryptocurrency Prices by Market Cap." Understanding this helps you interpret the list correctly — a coin with a small circulating supply but a high price can rank below a cheaper coin with a large supply.

Free vs. paid: what to know before choosing

The site is usable for browsing prices, charts, and rankings without an account. Paid options appear in two places: a Premium plan (the pricing page advertises removing ads) and API plans (the API pricing page shows a discount offer). Exact prices, rate limits, and what each tier includes are not specified in the available page content, so check the pricing pages directly before committing — especially if your use depends on API call volume.

Practical tips for getting useful answers

• For a quick market read: start on the homepage for total market cap, volume, and dominance, then scan top gainers and trending coins for what is moving.
• For research on one coin: open its row to see charts and historical data rather than relying on the single price figure.
• For recurring tracking: create a portfolio and enable app notifications instead of refreshing the page.
• For building something: confirm API tier limits and terms on the API pricing page first; the free browsing experience does not imply free API access at scale.

One caution: aggregator data reflects what exchanges report, and very large percentage moves on small-cap coins (the sample data includes a coin up over 2,000%) usually signal thin liquidity rather than a reliable trend. Cross-check any coin you plan to act on against its underlying market data.
