The cryptocurrency market is buzzing with speculation as altcoins show early but compelling signs of gearing up for a major surge. In the second quarter of 2025, the total market capitalization of altcoins—excluding Ethereum—jumped by $126 billion, reigniting conversations around the long-anticipated "altseason." With technical indicators flashing bullish signals and investor sentiment warming, analysts are divided on whether this momentum will culminate in a historic rally or remain a false dawn.
A $126 Billion Surge Signals Growing Momentum
The most striking development in Q2 has been the dramatic rise in the TOTAL3 index, which tracks the combined market cap of all altcoins excluding both Bitcoin and Ethereum. This metric gained $126 billion in value, capturing the attention of market watchers who view it as a leading indicator of broader altcoin strength.
Crypto analyst Javon Marks recently shared a compelling chart on X comparing the TOTAL3 index against the US money supply. The divergence—where altcoins are appreciating relative to total US liquidity—suggests increasing capital inflow into alternative digital assets.
“Altcoins have bounced off of the breakout retest against the US money supply and can deliver one of their most powerful runs since 2017!”
This statement underscores growing optimism. The 2017 bull run saw altcoins like Ethereum, Ripple, and Litecoin surge by thousands of percent, driven by retail enthusiasm and ICO mania. If history rhymes, today’s macro backdrop—marked by potential monetary easing and rising institutional interest—could fuel a similar, if not stronger, cycle.

Bullish Patterns Emerge: Inverse Head-and-Shoulders Formation
Adding credibility to the bullish thesis, anonymous trader Moustache identified a weekly inverse head-and-shoulders pattern forming in the TOTAL3 chart—a classic technical signal of a potential trend reversal from bearish to bullish.
This pattern closely mirrors the setup seen in 2021, just before top altcoins surged 174% against Bitcoin’s more modest 20% gain in the final leg of that cycle. Such a divergence often occurs when capital rotates out of Bitcoin and into higher-risk, higher-reward altcoins—a hallmark of full-blown altseasons.
If the current pattern plays out similarly, analysts expect substantial upside across the altcoin ecosystem, particularly for projects with strong fundamentals and real-world utility.
Mixed Sentiment: Caution Amidst Optimism
Despite the enthusiasm, not all experts are convinced that an altseason is imminent. Technical analyst Crypto Scient warns that while short-term momentum is positive, there hasn’t yet been a confirmed shift in the higher time frame (HTF) trend. He points out that the TOTAL2 index—tracking all cryptocurrencies excluding Bitcoin—remains below key resistance at $1.25 trillion and continues to trade in a bearish structure.
“Since both BTC and TOTAL are near the resistance zone and TOTAL2 still has some room, I am inclined to believe that we are distributing.”
This suggests that recent gains may reflect profit-taking or redistribution rather than sustained accumulation—a nuance critical for investors assessing market health.
Similarly, crypto commentator DonaXBT emphasizes that a true altseason cannot emerge without a significant decline in Bitcoin dominance. Currently above 60%, Bitcoin’s share of the total crypto market remains elevated, indicating that capital is still prioritizing the flagship asset.
However, DonaXBT notes a potential catalyst: if Bitcoin dominance drops below 60% and retests support between 56% and 58%, it could trigger a large-scale rotation into altcoins. Historically, such shifts have preceded explosive moves in assets like Solana, Avalanche, and Polkadot.
Trading Volumes Hint at Early-Stage Recovery
One of the most telling signs that altcoins may be in the early innings of a rally comes from spot trading volume data. According to CryptoQuant, daily altcoin spot trading volumes average between $3 billion and $5 billion—well below the $8 billion to $12 billion range seen in Q4 2024.
Low volume during price appreciation often indicates quiet accumulation, where informed investors build positions before broader market participation kicks in. This phase typically precedes high-momentum phases when retail traders enter en masse.
Furthermore, the Altcoin Season Index (ASI) currently stands at 24. As reported by Blockchaincenter.net, an ASI below 25 confirms that the market is still in “Bitcoin season,” where BTC leads performance. However, this setup is often ideal for what follows: once Bitcoin stabilizes or consolidates, capital naturally flows into altcoins seeking outsized returns.
When the ASI climbs above 30–40, it historically correlates with explosive altcoin rallies. The current reading suggests we’re on the cusp of such a transition.

Frequently Asked Questions (FAQ)
Q: What defines an "altseason"?
A: An altseason occurs when a broad range of alternative cryptocurrencies (altcoins) significantly outperform Bitcoin over an extended period. It’s typically marked by double- or triple-digit percentage gains across major and mid-cap altcoins, fueled by capital rotation from Bitcoin.
Q: How is the Altcoin Season Index calculated?
A: The Altcoin Season Index measures how many top 50 cryptocurrencies (excluding Bitcoin) are outperforming Bitcoin over a set period. A score above 75 indicates strong altseason conditions; below 25 suggests Bitcoin dominance.
Q: Can altcoins rally even if Bitcoin isn’t rising?
A: Yes, though rare. Most major altcoin rallies occur during overall bull markets. However, relative strength—where altcoins rise against Bitcoin—even during BTC consolidation, can signal improving market breadth.
Q: What role does liquidity play in altcoin performance?
A: Increased liquidity, especially from macroeconomic easing or institutional inflows, tends to benefit risk-on assets like altcoins first. As seen in the TOTAL3 vs. US money supply chart, rising liquidity often precedes altcoin outperformance.
Q: Are low trading volumes bullish or bearish for altcoins?
A: In early recovery phases, low volumes with rising prices can be bullish—they suggest accumulation. But sustained low volume during price drops may indicate lack of interest or distribution.
Q: Which sectors might lead the next altcoin rally?
A: Historically, smart contract platforms (e.g., Ethereum, Solana), DeFi tokens, and AI-integrated blockchains have led rallies. Projects demonstrating real usage, ecosystem growth, and innovation tend to outperform.

Conclusion: On the Brink of Something Big?
While debate continues among analysts, the data paints a picture of an altcoin market transitioning from dormancy to awakening. With technical patterns aligning, capital beginning to rotate, and key indices suggesting a shift in momentum, many believe we’re witnessing the early stages of what could become the most powerful altcoin rally since 2017.
Whether this culminates in a full-blanket altseason depends on several factors: sustained capital inflows, a drop in Bitcoin dominance, and broader macro support. For now, patient investors may want to monitor the Altcoin Season Index, TOTAL3 trends, and spot volume dynamics closely.
One thing is clear: the groundwork is being laid. And when the floodgates open, early observers could be best positioned to benefit.
