币界网报道：The Altcoin Season Index has dropped 12%, signaling a potential shift towards Bitcoin dominance in the crypto market. The index, which measures the performance of altcoins relative to Bitcoin, indicates that altcoins may be underperforming as investors pivot to BTC. Analysts note that Bitcoin's recent price stability and institutional interest could be driving this trend, with altcoins struggling to maintain momentum. Historically, such declines in the Altcoin Season Index have preceded periods where Bitcoin outperforms smaller-cap cryptocurrencies. Market participants are closely watching for further signals of capital rotation, as a sustained drop could mark the beginning of a prolonged Bitcoin-dominant phase. The current reading suggests altcoins have lost significant ground, though seasonal patterns leave room for potential reversals later in the cycle.
