Bitcoin News Today: Altseason Index Jumps 155% Indicating Altcoin Strength

The Altseason Index has surged from 20 to 51, indicating a significant shift in market dynamics towards altcoin strength. This index is designed to compare the performance of altcoins relative to Bitcoin, with levels above 75 historically marking strong altcoin seasons and readings under 25 indicating Bitcoin dominance. The recent breakout from the 25–40 range reflects renewed momentum and increased altcoin outperformance.

Over the past two months, the index has risen steadily, recovering from a prolonged period of Bitcoin dominance. From early May, the metric remained within the 10–30 range, indicating stronger Bitcoin performance. However, a breakout occurred in late June, pushing the index above 40 for the first time since March. This upward move suggests that altcoins have recently begun outperforming Bitcoin across several timeframes. Notably, the index’s current reading of 51 is the highest in over three months, underscoring a shift in market preference.

The Altseason Index’s ability to break out of the 25–40 consolidation range further validates this momentum. Traders are closely monitoring whether this upward trajectory will continue toward the 75 level. Historical data from November 2024 shows that when the index peaked above 80, altcoins experienced significant price rallies. Conversely, when the index remained below 25, Bitcoin led the market. The current rise from the 20-level floor to 51 reflects renewed interest and buying pressure in alternative cryptocurrencies.

From July 2024 to March 2025, the index exhibited multiple swings between Bitcoin and altcoin seasons. This cyclical pattern highlights the constant rotation of capital between the two market segments. Recent data shows that Bitcoin dominance has been weakening, as reflected by the rapid climb of the index over the past few weeks. The visual gradient on the chart also emphasizes that the index has entered a neutral-to-bullish zone for altcoins. If the trend persists, the metric could potentially test its higher boundary levels seen in late 2024. For now, the Altseason Index remains firmly in an upward trajectory, with its latest reading marking a key turning point since early March.
