Bitcoin Dominance: Altcoin Season Index Plunges to 26

The CoinMarketCap Altcoin Season Index has plummeted to 26, signaling that the current market is firmly in a Bitcoin-dominated phase. This index tracks the performance of the top 100 cryptocurrencies by market capitalization against Bitcoin over the past 90 days.

When 75% or more of these top 100 coins outperform Bitcoin, it's considered an 'altcoin season.' In contrast, when fewer coins beat Bitcoin, it's a 'Bitcoin season.'

The current reading suggests only a minority of altcoins have managed to outperform Bitcoin in the recent quarter. This aligns with a period where Bitcoin has captured a larger share of market attention and capital.
