Altcoin Index Stalls at 41 as 2025 Resistance Retest Mirrors 2019 and 2021 Cycles

• Altcoin Index currently stands at 41, below the threshold for confirming an altseason.
• Altcoin market cap reached $1.50 trillion in July, showing steady growth despite Bitcoin’s dominance.
• 2025 resistance tests and MACD crossovers resemble the 2021 altseason setup, indicating repeated historical patterns.

The altcoin index market has shown steady growth through July, with capitalization climbing despite Bitcoin’s continued dominance. Recent readings from the CMC Altcoin Season Index place the current value at 41, below the altseason confirmation threshold.

Altcoin Index Sees Steady Growth as Index Remains Below Season Threshold

Tracking the current position, CoinMarketCap reveals that the altcoin market has seen consistent growth in capitalization through July, although current data shows Bitcoin still leading. Based on the latest figures from the CMC Altcoin Index , altcoins are yet to outperform Bitcoin across the top 100 tokens. The index sits at 41 out of 100, which remains under the 75 mark required for an official altcoin season.

As of press time, the Altcoin Index stood at 43, paired with a market capitalization of $1.50 trillion. Since then, the index has decreased slightly, now resting at 41. Yesterday’s reading was 35, while the previous week showed 42. One month ago, the index was 21, reflecting a period of strong Bitcoin dominance.

The yearly high for the index was 87, recorded on December 4, 2024, during peak altcoin momentum. In contrast, the lowest value reached 12 on April 26, 2025. Over the past 30 days, altcoin market capitalization has continued to climb, even though index levels stayed under 50. This trend indicates capital inflow toward altcoins, but not enough performance strength to signal a full transition away from Bitcoin.

Repeated Resistance Reaction Unveils as 2025 Aligns With Prior Seasonal Trends

With an index reading of 43, Moustache’s recent observation reveals that a key altcoin resistance level dating back to 2019 was once again tested in mid-2025. The chart tracks multiple interactions with this level across several years, with each instance followed by defined altseason activity. Past touchpoints in 2019, 2020, and 2021 each triggered movements labeled as mini or full altseasons.

In 2025, the altcoin chart again reached this resistance zone. A downward shift followed, resembling previous reactions. The highlighted section for 2025 shows the same setup seen during the major altseason of 2021. That year also included a strong altcoin rally followed by a correction.

The MACD indicator shows a bearish crossover in 2025. A similar crossover occurred in 2021 before a broad altcoin rise. The MACD histogram also turned from green to red, indicating declining momentum. The chart presents a recurring setup where the price meets resistance, MACD crosses, and altcoins gain dominance. This multi-year resistance continues to act as a ceiling for altcoin strength. Each break attempt historically preceded notable market shifts led by altcoins.

Altcoin index performance continues to trend upward, though it remains below levels required to confirm a full seasonal shift. MACD crossovers and repeated resistance tests mark consistent patterns aligned with past altcoin-led rallies. Current conditions indicate structural similarities to prior cycles, setting the stage for continued altcoin market activity.
