Crypto: Altcoins Take Their Revenge On Bitcoin

While bitcoin struggles to catch its breath, altcoins are capturing the market’s attention. The Altcoin Season Index surpasses 50, signaling a rotation phase toward alternative assets. But is this momentum truly solid, or is it just a flash in the pan?

Altcoins: a key index surpasses 50, the start of the real season?

Within a few days, the Altcoin Season Index (ASI) rose from 39 to 51, crossing the technical threshold that marks entry into an altseason. This composite indicator measures the performance of the top 50 altcoins against bitcoin over a 90-day period. Historically, a score above 75 signals true altcoin euphoria; at 51, the market enters a gray zone, one of hope rather than certainty.

This level, although modest at first glance, represents a noticeable regime change. It reflects a rising interest from investors in narrative-driven alternative projects, contrasting with bitcoin’s current slow pace.

Analysts disagree on the viability of the Altseason

The altcoin season bursts: the index hits 51 as hype reaches a boiling point, fueled by a series of unexpected rallies and growing euphoria on social media. But not all observers share the enthusiasm this figure seems to inspire. For analyst CW8900, we are only at the very beginning of a broader movement. He mentions a favorable technical setup on the total altcoin market cap, but without real macroeconomic validation.

In contrast, Miles Deutscher talks about a “popcorn season“: tokens appear from nowhere, briefly explode, then fall back. A disorderly dynamic, hard to follow and even riskier to trade. According to him, the classic mistake is chasing gains instead of understanding what fuels them. Caution remains advisable despite the rise of the ASI index.

Altcoins: simple hype or real recovery like in 2017?

Beneath the surface performance lie micro-narratives as varied as they are volatile:

• AI tokens;
• Memecoins;
• Community ecosystems.

These segments attract speculative attention but lack clear fundamental consolidation. And to make matters worse, the underlying data offers little clarity. Volume remains fragmented, bitcoin dominance slightly declines without collapse, and institutional funds show a marked preference for regulated products around BTC, such as spot ETFs. As it stands, it is hard to say whether this rotation is structural or purely tactical.

A look back at previous cycles (2017, 2021) shows that altcoins often take over once bitcoin has entered a prolonged consolidation. The current rise could therefore fit a classic pattern, with a gradual rotation toward L1 infrastructures, L2 solutions, and some DeFi protocols.

Weakened Bitcoin? The crypto king facing the return of altcoins

Bitcoin moves without a clear direction, caught in a narrow range despite macro decisions. Its volatility, now moderated by spot ETFs, limits its upward excesses. The market seems to prefer more dynamic altcoins, fueled by narrative stories. This transition raises a key question: does bitcoin remain the market’s center of gravity, or is it sliding into a more passive role?

Historically, altcoin outperformance phases have been temporary. However, the recent drop in BTC dominance to 61% might indicate a temporary shift toward sector-specific logics, eroding bitcoin’s historic leadership in favor of other assets.

Altcoins are gaining ground, benefiting from a wait-and-see moment on bitcoin. But history shows these disconnection phases are rarely lasting. If BTC regains strength, it could once again attract capital. Meanwhile, investors are watching the subtle signals to guess whether this altseason has what it takes to last… or if it will once again be absorbed by the king’s weight.
