The Vibe: How much of the entire crypto market belongs to Bitcoin.
The Details: Bitcoin dominance (or BTC dominance) is Bitcoin’s market cap divided by the total market cap of all cryptocurrencies combined, shown as a percentage. When it’s high (like over 50-60%), money tends to flow into Bitcoin as the “safe” choice during uncertain times. When it drops, money moves into altcoins, often signaling the start of altseason with bigger pumps in smaller coins.
Pro Tip: Track it on sites like CoinMarketCap or TradingView. Falling dominance in a bull market is a classic sign that alts are about to run hard—rising dominance can mean Bitcoin is leading or people are seeking safety in bears.
