What is Dominance?
Crypto Glossary Definition
This term refers to the percentage of the total crypto market cap that any specific cryptocurrency currently occupies. BTC Dominance, for example, is the BTC market cap divided by the total crypto market cap.
Why Dominance Matters
Bitcoin dominance is Bitcoin's share of the total crypto market cap — rising dominance usually signals capital rotating out of altcoins into Bitcoin (often during uncertainty), while falling dominance typically accompanies "alt season" rallies.
Dominance in Practice
An analyst tracking the crypto market notices Bitcoin's dominance climbing steadily over several weeks, even as the total crypto market cap stays roughly flat, which tells her that capital is rotating out of altcoins and into Bitcoin rather than new money entering the market overall. This pattern typically shows up during periods of uncertainty, when investors want exposure to crypto but prefer Bitcoin's relative stability and liquidity over smaller, more volatile alternatives. A few months later, she notices the opposite trend: Bitcoin dominance falling while altcoins across the board post outsized gains, a shift often described in crypto communities as the start of an 'alt season,' where risk appetite has returned and traders are rotating profits from Bitcoin into smaller-cap tokens chasing higher percentage returns. She uses dominance as one input in deciding how to allocate between Bitcoin and altcoins in her own portfolio, treating a rising trend as a signal to lean more conservative and a falling trend as a signal that risk-on altcoin exposure may be paying off. Dominance is a simple ratio — a coin's market cap divided by the total crypto market cap — but tracking how that ratio shifts over time gives traders a rough read on where sentiment and capital are flowing within the broader market.
