Bitcoin Market Overview: Market Cap, Dominance, Volume & Derivatives

This page gathers Bitcoin market data in one place: the FMchart composite price, market cap and rank, 24-hour spot volume and Bitcoin dominance, next to open interest, funding and liquidations from the exchanges FMchart tracks. Because BTC anchors the crypto market, seeing its spot activity and derivatives positioning side by side shows what is driving the wider market.

Data transparency

  • Price and spot volume: FMChart composite candles for BTC built from several spot exchanges, hourly; the 24H spot volume sums the last 24 closed hourly candles.
  • Market cap and rank: FMChart market snapshot (composite price × circulating supply), refreshed every minute.
  • Open interest: one side of BTC perpetual futures, summed over the derivatives exchanges FMChart collects; the exchange breakdown is the latest snapshot.
  • Funding: rate of each exchange converted to an 8-hour equivalent (rate × 8 ÷ settlement interval), weighted by open interest.
  • Liquidations: long and short liquidations reported by the exchanges FMChart collects.
  • Liquidation heatmap: estimated from open interest, prices and an estimated leverage mix — not liquidations that have happened (same model as the Liquidation Heatmap page), last 30 days.
  • Long/short ratio: Binance global accounts ratio, hourly (only when Binance publishes it for BTC).

Bitcoin FAQ

How is Bitcoin's market cap calculated on this page?

Market cap is the FMchart composite BTC price multiplied by Bitcoin's circulating supply, shown with its rank among the coins FMchart tracks. The composite price blends spot prices from the exchanges FMchart tracks and updates hourly, so market cap moves with that index rather than with one exchange's last trade.

What does Bitcoin dominance show next to volume and open interest?

The market share panel compares Bitcoin's market-cap dominance with its share of spot volume, derivatives volume and open interest. When BTC's trading or leverage share runs above its dominance, activity is concentrating in Bitcoin; when it runs below, traders are more active in other coins.

What is the Bitcoin liquidation heatmap?

It is an estimated map of price levels where leveraged BTC positions could be liquidated, drawn over the price for the past 30 days. Bands with higher intensity mark levels with more estimated exposure. These are modelled levels, not recorded events; recorded liquidations appear in the long/short bars.

How do I read the Bitcoin price, volume and open interest chart?

The chart shows hourly composite price, spot volume and open interest over 7 days. Price rising on higher spot volume points to buying in the spot market; price rising mainly with open interest points to leverage in futures and perpetuals. Each panel links to the full FMchart tool for more history.
