The Altcoin Season Index Points To A Resurgence Of Altcoins Despite Bitcoin's Dominance

Altseason is playing the waiting game. While Bitcoin continues to take center stage, other crypto assets are holding back. Yet, within this stifling dominance, cracks are appearing. Certain technical and historical data suggest that a turnaround is being prepared behind the scenes. Altcoins may not be down for the count. They are waiting, watching, accumulating. The awakening could be surprising.

A Summer Like the Previous Ones: Calm Before the Surge?

All eyes are on the Altcoin Season Index, the gauge comparing the performance of the top 50 altcoins against bitcoin. In July 2025, the index bounced back to 27 after nearly hitting the abyss at 11. This number, modest as it may be, evokes a striking memory: in 2020, the index dropped to 8… just before a legendary rally.

Analyst Michaël van de Poppe fuels this hope: “For the past five years, the Altcoin Season Index has hit a bottom in summer, mainly in June. What followed? A strong second half of the year for altcoins.”

Since 2020, each summer has followed the same scenario: capitulation, market bottom, then explosion. This repetitive pattern inspires those who believe crypto markets are cyclical. Summer 2025 could very well be a remake of those prosperous years. The signals repeat. History might stammer again.

ETH, Total 2, Accumulation… Altcoins Are Setting Their Markers

Those watching charts and candlesticks see a reversal structure forming. The “Total 2” index, representing capitalization excluding bitcoin, has climbed 35% since April. More importantly, it has made a “higher low” – a low higher than the previous one. This pattern often signals a reversal.

According to analyst Daan, if bulls can push the Total 2 index above the 2024 peak, it would confirm a higher high – the final piece to structurally reverse the market. 

Ethereum, on its side, consolidates within a narrow range, between $2,400 and $2,700. Meanwhile, the ETH/BTC ratio tries to stabilize around 0.023 BTC. A breakout above 0.027 BTC would be a major signal.

Investor activity follows suit. Accumulation movements are visible, and not only on ETH. Altcoins like Solana, FLOKI, or even PEPE are seeing volume increase. The macro context becomes more welcoming. Risk is reclaiming its place. The dice may be quietly but surely being cast.

Why Traders Don’t Give Up on Altcoins

Despite headwinds, enthusiasts of the altcoin season keep the faith. For them, there are precedents. There are signals. And above all, there are numbers.

Some concrete markers:

• 27 is the current score of the Altcoin Season Index. Low, but far from the historical minimum;
• 35% is the increase of Total 2 since April, marking renewed interest outside bitcoin;
• 0.023 BTC is the support ETH has defended against Bitcoin since mid-June;
• 50% is still the distance most altcoins are from their all-time highs;
• 5 is the number of consecutive summers where the Index dipped in June before rising sharply.

Experienced investors know: the crypto market often rewards those who take positions when everything seems uncertain. Michaël van de Poppe’s tweet sums up this confidence:

Given that we are mid-bull market and QE is easing, it is very likely we are witnessing a movement much stronger than that of Q4 2023.

Altcoins haven’t said their last word yet. They move stealthily, driven by a silent force.

In the crypto world, it’s better to avoid hasty certainties. Even if some analysts claim that bitcoin’s dominance could block altcoins for a long time, history shows anything can change. And often, it starts when nobody believes anymore.
