Understanding Bitcoin Dominance (BTC.D)
Bitcoin dominance measures Bitcoin's market capitalization as a percentage of the total cryptocurrency market. This key metric reflects Bitcoin's influence within the broader crypto ecosystem. Calculated by dividing Bitcoin's market cap by the combined market cap of all cryptocurrencies, then multiplying by 100, it serves as a pulse check for market sentiment.
Why It Matters:
- High dominance (>60%): Signals investor confidence in Bitcoin over altcoins
- Low dominance (<40%): Indicates altcoin season with capital flowing to alternative assets
