Bitcoin rises from 80k to Altcoins surge together, internal logic of capital rotation

BTC reclaims above $81,000, ETH approaches $2,400, and altcoins rebound in sync—currently, the market shows signs of full resonance. The underlying capital logic behind this phenomenon is: Bitcoin first breaks through a key psychological threshold, opening up the pricing space for the entire crypto market. The profit-taking effect spills over from BTC to ETH, then from mainstream coins to the altcoin sector, forming a classic three-stage rotation. However, it should be noted that historically, this resonance pattern has two outcomes: one is continuous influx of new capital, leading to a comprehensive market upgrade; the other is that after the capital rotation within the market completes, a lack of new inflows causes a collective pullback. Currently, indicators such as stablecoin issuance and ETF net inflows are positive, but geopolitical uncertainties remain a variable hanging overhead. Whether the resonance can evolve into an upgraded resonance depends on the coordination of macroeconomic conditions and regulatory developments.
