Understanding the Altcoin Season Index and Bitcoin’s Continued Dominance in the Market.
The Altcoin Season Index, currently sitting at 36, reveals that the cryptocurrency market is still predominantly in Bitcoin season. This metric, which tracks the performance of the top 100 cryptocurrencies over the last 90 days, shows that Bitcoin continues to outperform altcoins. Despite brief rallies in the altcoin sector, the market remains Bitcoin-centric.
The Altcoin Season Index provides significant insights on market patterns, allowing investors to assess whether altcoins outperform Bitcoin. Altcoin season is typically defined as 75% of the top 100 altcoins outperforming Bitcoin. The index had peaked at 64 in December 2024, indicating a beginning trend towards cryptocurrency domination. However, the index has fallen back below 40 since the beginning of 2025, implying that Bitcoin will continue to dominate for some time.

Historically, Bitcoin season refers to the period during which Bitcoin’s price rises while altcoins fall behind. This phase is frequently characterised by strong investor confidence in Bitcoin, as the first cryptocurrency continues to dominate the market with significant price increases and mainstream attention. In contrast, altcoins typically climb during altcoin seasons, when they outperform Bitcoin.
Bitcoin’s present dominance demonstrates its durability, as it continues to be a safe haven for crypto investors seeking stability in the face of volatility. While cryptocurrencies show hints of development, they are still unable to keep up with Bitcoin’s advances.
In the following months, investors will be looking for signs of a potential market shift. A surge in altcoin performance could drive up the Altcoin Season Index, but for the time being, Bitcoin remains the market’s dominant power. If the trend of underperformance among altcoins continues, we may see a Bitcoin-dominated market for the foreseeable future.
