Bitcoin Dominance Shift

Definition ∞ Bitcoin Dominance Shift refers to a change in Bitcoin’s proportion of the total cryptocurrency market capitalization. This metric indicates whether Bitcoin is gaining or losing market share relative to alternative digital assets. A shift often reflects investor sentiment, signaling either a flight to Bitcoin as a perceived safe haven or a rotation into altcoins during periods of higher risk appetite. Such movements influence broader market trends and asset allocations across the crypto ecosystem.
Context ∞ The current market discussion frequently examines Bitcoin dominance as a gauge of overall market health and the potential for an altcoin market rally. A sustained decline in Bitcoin dominance might suggest increasing investor confidence in alternative digital assets. Conversely, a rise could indicate market uncertainty or a preference for Bitcoin’s established liquidity. Future developments often relate to macroeconomic factors or significant protocol upgrades impacting either Bitcoin or major altcoins.
