BTC dominance measures its market share relative to other cryptocurrencies. Shifts in dominance often indicate capital rotation into or out of altcoins. Monitoring dominance alongside trading volume, derivatives activity, and exchange flows provides insight into market sentiment and potential altcoin performance. Investors use BTC dominance trends to anticipate shifts in liquidity, manage portfolio allocations, and identify periods favorable for altcoin accumulation or BTC reentry.
