One of the two main crypto aggregators alongside CoinMarketCap. Prices, charts, market cap, volumes and community scores for 15000+ coins. Has its own trust score system for exchanges and a solid free API that half the crypto industry runs on. The premium subscription gives you advanced charts, exclusive data and no ads, but honestly the free version covers 95% of what you need. If CoinMarketCap is Binance's territory, CoinGecko is the independent alternative that everyone respects.
