CoinGecko

The most-used crypto price and market data aggregator. Free tier covers 95% of needs.

free + proFor beginnerVisit site

Tracks 15,000+ cryptocurrencies across 1,000+ exchanges. Live price, market cap, volume, historical charts, and token info pages. The Fear & Greed Index and trending tokens are popular discovery surfaces.

The 3 most valuable pages

1. Token detail page

Shows: current price, 24h/7d/30d change, market cap, FDV (fully diluted valuation), circulating supply, all-time high/low, exchange pairs. Critical metric: FDV vs market cap — if FDV is 10x market cap, huge unlock supply coming.

2. Exchange listings

Shows where a token trades, with volume and spread per pair. Useful for: verifying a token isn't only on one sketchy DEX, finding best price.

3. Trending page

Shows what retail is searching for. Often leading indicator of meme-driven moves. Caveat: not alpha, just where attention is concentrated.

Things to check before buying any token

  1. CoinGecko's verification badge (blue check)
  2. FDV / market cap ratio
  3. Top 10 exchanges it trades on (avoid if only on unknown DEXes)
  4. Market cap > $10M (below is illiquid, hard to exit)

Pros

  • Largest coverage (more tokens than CoinMarketCap)
  • Free tier is genuinely useful
  • Good API with 10,000 free calls/month
  • Independent (not owned by an exchange)

Cons

  • FDV can be misleading for fully-unlocked tokens
  • Trending section attracts meme speculation
  • Minor chains can have stale data
