The cryptocurrency market is showing clear signs that an altseason could be imminent, with the Altseason Index reaching 61 over the weekend, the highest level since 2025.

This indicator measures the performance of altcoins relative to Bitcoin. An altseason occurs when most alternative cryptocurrencies significantly outperform Bitcoin over a sustained period, attracting investors' attention to smaller-cap projects.

Currently, 59% of the top 50 cryptocurrencies, excluding stablecoins and tokenized versions of bitcoin, outperform BTC over a 90-day period.

While this falls short of the 75% threshold required to declare an altseason (according to the Blockchain Center, the index's creator), the trend shows sustained demand for lower-cap assets.

For example, ether (ETH), Ethereum's cryptocurrency, has seen significant weekly gains and new all-time highs, while bitcoin moderates its rally. This trend corresponds to phase 2 of the cryptocurrency cycle.

Despite these advances, an altseason is not yet in the making. Capital turnover and the performance of cryptocurrencies will continue to be key in determining whether the market crosses that threshold in the coming weeks.
