About this data
Dominance figures are live, pulled from CoinGecko's free public API every time this page loads — no paid key needed.
A day-by-day historical dominance chart isn't included: CoinGecko's free tier doesn't expose a historical global-market-cap series, only the current snapshot, and computing one accurately requires a paid endpoint. The live current split above is genuine and free either way.

Why Bitcoin dominance matters
Rising dominance usually means capital is concentrating in Bitcoin — often during uncertain periods, when it's viewed as the safer crypto asset. Falling dominance tends to coincide with altcoins gaining ground, which is why this figure is often read alongside the Altcoin Season Index above.
