Bitcoin Dominance (BTC.D)
Bitcoin's share of the total crypto market cap. Rising dominance means capital rotating into BTC, falling means altcoins are outperforming.
Bitcoin dominance today is 58.74% of the total crypto market cap.
Bitcoin dominance (BTC.D) is BTC's market capitalization divided by the total crypto market cap, expressed as a percentage. It is the fastest single read on capital rotation: dominance rising while the market climbs means new money prefers BTC, dominance falling in a rally is the classic altseason signature, and dominance rising in a selloff means altcoins are bleeding harder than Bitcoin. Binance even lists a tradeable perpetual on it, BTCDOMUSDT, which tracks BTC dominance against the top 20 altcoins so you can express a rotation view directly.

Rising dominance means capital is rotating into Bitcoin relative to altcoins, which is typical of risk-off phases or early bull markets. Falling dominance during a market-wide rally is the classic altseason signature, when altcoins outperform BTC.
What is BTCDOMUSDT?
BTCDOMUSDT is a Binance USDT-margined perpetual futures contract that tracks a BTC dominance index measured against the top 20 altcoins. It lets traders go long or short on Bitcoin dominance itself rather than on any single coin's price.
Is Bitcoin dominance the same on every site?
No. The headline BTC.D number depends on how many coins the data source counts in the total market cap. TradingView, CoinGecko and CoinMarketCap can differ by a point or two, and Binance's BTCDOM index uses only the top 20 altcoins, so its level is on a different scale entirely.
