Altcoin Season Index Surges Past 76 Points — Hitting Highest Level Since December

Altcoins are stealing the spotlight again—and this time, they’re not playing nice.

The Altcoin Season Index just blasted past 76 points, marking its strongest performance since December 2024. That kind of momentum doesn’t just happen—it screams opportunity.

What’s driving the rally?

Market rotation out of Bitcoin, renewed retail interest, and a handful of mid-caps posting triple-digit monthly gains. Sound familiar? It should—it’s the same script from every previous cycle, just with better graphics.

While the big boys in traditional finance are still trying to figure out how to short volatility without getting rekt, altcoins are doing what they do best: moving fast, breaking things, and making early believers very, very happy.

Just remember—what goes up fast can come down faster. But for now? The altseason pump is very, very real.

The growth of the altcoin season index is a mix of solid performance from blue-chip assets and rapid pumps from new projects or returning altcoins and tokens from previous bull markets. The main drivers of the current altcoin season are a solid ETH performance and a baseline $4,300 price, while SOL recovered above $225 and BNB holds close to its records above $900. 

Altcoin season index breaks above December 2024 levels

The altcoin season index broke above 76 points for the first time since December 2024, boosted by several recent pumps from high-profile tokens. While those pumps may not be sustainable, the market has shown some appetite for short-term risk. 

Over the years, altcoin seasons have been shorter, as the market is oversaturated with assets. However, during that short time, new narratives make fast MOVE and reach peak valuations. 

This time around, the altcoin season happened as BTC dominance was around 56%, while ETH had a 13.6% share of the total market cap. As usual, the altcoin season followed the ETH breakout, though not all assets were connected to the ethereum ecosystem. 

Altcoin season boosted by selected asset pumps

Based on social media sentiment, some of the old narratives are barely active. This time around, altcoin season has not lifted all assets, and some coins and tokens from previous bull markets are still far from their all-time peak. 

The performance of the top 100 assets is skewed by selected pumps. This time around, the altcoin season may hinge on several high-profile projects creating deliberate HYPE with their communities. 

One of the top-performing tokens during the past day was MYX, a relatively new project that launched in May at $0.08. Later, in August, MYX climbed to around $2.59, before shooting up to its recent all-time high at $26.75. 

MYX saw a sudden inflow of fresh capital in the past week, with volumes growing seven times to over $350M per day. The token easily reached a market cap above $3.5B, becoming the top-performing asset to determine the altcoin season index. 

Other sudden pumps include Ethernity Chain, breaking out by 312% to $2.49, Naoris Protocol adding 58% and Elastos, up over 35%. Those pumps are far ahead of the performance of older assets, and show an element of short-term hype or possibly deliberate pumps. 

In those cases, even obscure tokens can trigger short liquidation cascades and a squeeze to a higher price range. MYX is considered a deliberately engineered short squeeze, which may not be sustainable. However, the appeal of rapidly appreciating tokens means some traders may still chase those pumps for a chance at finding rapidly appreciating tokens, not even connected to a specific narrative.
