Market Dominance Ratio

The Market Dominance Ratio measures the proportion of the total cryptocurrency market capitalization held by a single asset, most commonly Bitcoin. It serves as a barometer for market sentiment, indicating whether capital is flowing into established assets or rotating into riskier altcoins.

A high dominance ratio suggests a risk-off environment where investors seek the safety of the largest, most liquid assets. Conversely, a falling dominance ratio often precedes an altcoin season, where speculative capital moves into smaller, higher-growth tokens.

Traders use this ratio to time market cycles and adjust their portfolio allocation between core holdings and speculative bets. It is a key metric for understanding the macro-structure of the digital asset landscape.
