What CoinGecko's Global Market Cap, Trading Volume, and Dominance Figures Mean

CoinGecko's homepage header shows three market-wide numbers: global market cap (the total value of all cryptocurrencies it tracks), 24h trading volume (how much was traded in the past day), and BTC/ETH dominance (each asset's share of total market cap). Together they give a quick read on market size, activity, and concentration. On the homepage snapshot, for example, global market cap was $2.74 trillion (up 2.3% in 24 hours), 24-hour volume was $45.03 billion, Bitcoin dominance was 58.4%, and Ethereum dominance was 10.3%, across 22,501 tracked coins.

Global market cap: how big the market is

CoinGecko defines crypto market cap as price multiplied by circulating supply, summed across every coin it tracks. The headline figure is that sum, so it moves when prices move, when supplies change, or when new coins are added to the tracker.

• What it tells you: the overall size and direction of the market. A 2.3% daily change on a $2.74T base is roughly $60B of value added or removed in a day.
• What it doesn't tell you: whether gains are broad or concentrated in a few large coins. Pair it with dominance and the gainers/losers lists.
• Watch the tracked-coin count. CoinGecko was tracking 22,501 cryptocurrencies in the snapshot. The universe expands over time, so compare market cap over short windows rather than years apart if you want a clean signal.

24h trading volume: how active the market is

Volume is the total value traded across tracked markets in the last 24 hours. In the snapshot it was $45.03B, alongside a 20.6% figure that reflects the change in volume versus the prior period.

• Rising volume with rising prices suggests broad participation.
• Rising volume with falling prices often signals heavier selling.
• Low volume means thin liquidity and prices that can move on relatively small orders.

Volume is a flow measure, not a stock measure: it resets every day and is not comparable to market cap in scale. A $45B daily volume against a $2.74T market cap means roughly 1.6% of total value changed hands that day.

Bitcoin and Ethereum dominance: how concentrated the market is

Dominance is an asset's market cap divided by the global market cap. Bitcoin at 58.4% and Ethereum at 10.3% means the two largest assets account for about 68.7% of tracked value, leaving roughly 31% for everything else.

• High and rising BTC dominance usually means capital is favoring Bitcoin over smaller coins, often during risk-off periods.
• Falling BTC dominance can indicate rotation into altcoins.
• Dominance is relative. It can rise even when Bitcoin's price falls, if other coins fall faster.

Reading the three together

Use these as context, not as trade signals. They describe the market as a whole and say nothing about any individual coin's prospects.

Where to verify and go deeper

The homepage header links to a fuller stats page ("View stats") for expanded metrics, and each coin's page shows its own market cap, volume, and supply data so you can check how it contributes to the totals. CoinGecko also publishes market insight summaries on the homepage, such as notes on Bitcoin consolidating near $80k amid options expiry and Fed uncertainty, which help explain why the headline numbers moved.

One caveat: figures are live and change constantly, so treat any number you see as a snapshot with a timestamp, not a fixed reference.
