With renewed macroeconomic tailwinds, shifting liquidity flows and growing institutional interest in digital assets, many believe conditions may finally be aligning for a compelling run in the altcoin sector.
Current market context and sentiment
In recent months, Bitcoin has held steady around critical support levels, following a strong run earlier in the cycle. Meanwhile, Ethereum and a number of mid-cap coins have shown tentative signs of strength. The market has broadly viewed this consolidation as a reset phase before the next leg up. The fact that cryptocurrencies Broader sentiment indicators have resumed upward momentum, suggesting interest in risky assets is picking up again.
A key metric that enthusiasts use is the Altcoin Season Index (ASI), which quantifies how many altcoins are outperforming Bitcoin. According to CoinDCX, the ASI has reached neutral territory – no confirmed altseason yet, but steadily improving – with Ethereum leading the recent gains. Meanwhile, BTC’s dominance (Bitcoin’s share of market cap relative to the rest) is showing signs of erosion, which has historically signaled capital rotation into altcoins.
Another telling data point: Recent studies show that approximately 90% of altcoins listed on Binance are trading below their long-term trendlines. While this paints a picture of general weakness, some analysts are interpreting this as a possible entry situation – markets often recover sharply as widespread capitulation gives way to renewed buying.
On the macro front, a catalyst many observers are citing is the recent tone of the US Federal Reserve. In a recent speech, Fed Chairman Jerome Powell indicated that no surprise rate hikes are expected and hinted that balance sheet contraction (quantitative tightening) could ease. This change in tone is seen as a possible harbinger of renewed liquidity flowing into risky assets – first to Bitcoin, then to Ethereum and finally to altcoins.
Overall, market participants are increasingly asking themselves: Will the fourth quarter of 2025 finally herald a sustainable alternative season?
What analysts say
Benjamin Cowen and the $5K ETH threshold
Crypto analyst Benjamin Cowen remains one of the most vocal skeptics when it comes to premature calls in the offseason. According to him, before altcoins can stage a meaningful rally, Ethereum must first rise above $5,000 and hold the level. If ETH cannot sustain that as support, any broad altcoin rally would be fragile at best.
Cowen also predicts that Bitcoin’s peak for the cycle could land somewhere between $130,000 and $155,000. If that happens, he argues, Ethereum and altcoins may have room to accelerate. But if BTC fails to break convincingly higher or loses key support, any altseason could fail.
Bitwise and institutional flows
From an institutional perspective, analysts at Bitwise have flagged several altcoins – Ethereum, Solana, Avalanche, Chainlink and XRP – as poised to see meaningful inflows in the fourth quarter. Their thesis rests on improving regulatory clarity (particularly for the US interpretation of spot ETPs), increasing institutional allocations to tokenization/DeFi themes, and broader momentum beyond just Bitcoin portfolios.
Bitwise’s argument is based on the idea that institutional capital already migrating to crypto will not remain locked in Bitcoin forever. Sooner or later, portfolio managers will seek higher upside in well-positioned altcoins.
The “Breakout” Camp and Declining BTC Dominance
Other analysts are watching for technical breakouts in indices that track altcoins, with the exception of Bitcoin. A recent article stated that the ‘TOTAL2’ index (market cap of cryptos excluding Bitcoin) is approaching previous highs, and if it breaks decisively, it could trigger a strong altcoin rally.
Crypto Rover, quoted there, also notes that Bitcoin’s dominance is weakening and is not strongly rejecting resistance levels – a classic warning that capital can shift.
Moreover, CCN recently published that Ethereum’s gains against Bitcoin have already begun to erode BTC’s dominance. Combined with bullish crossovers in technical momentum indicators, they suggest we may already be in the early stages of the altseason.
That said, some opponents warn against false starts. As one Medium author put it, markets can briefly see a spike in altcoin strength, after which the momentum fades and returns. Many altcoins are still well below their previous all-time highs, and retail sales are not yet fully active.
Macroliquidity cycles and global flow
The “liquidity story” is another thread underlying these expectations. A cryptocurrency-focused analysis argues that global liquidity typically leads crypto markets with a lag of around thirteen weeks, and that global liquidity is expected to peak around the fourth quarter of 2025. If so, this could provide a favorable backdrop for altcoins.
Still, it’s worth noting that while global liquidity may improve, the U.S. central bank remains relatively constrained. Delaying the QT is not the same as reintroducing aggressive easing. The timing and extent of the spillover to risk positions therefore remain uncertain.
What can go wrong (risks and counterarguments)
BTC dominance snapback. If Bitcoin regains dominance, capital could flow back into BTC, delaying or dampening altcoin gains.
Failed ETH breakout. If Ethereum fails to hold $5,000 or falls back after reaching it, many altcoins may lack the structural momentum to sustain gains.
Interest rate shocks/macro surprises. An aggressive Fed surprise or a geopolitical shock could reduce risk appetite and completely derail speculative flows.
The absence of retail. True alternative seasons often require retail FOMO to build momentum. If retail does not step in, the upside potential may remain limited.
Overflowing stories. Many altcoin stories (AI tokens, memecoins, layer 2s) are already busy; Valuations may be frothy or vulnerable to sharp declines.
Roadmap: What to watch in Q4
Here are the most important signals and events to monitor:
| Signal / Event | Why it matters |
|---|---|
| Ethereum breaks and contains $5,000 | Seen by many as a necessary trigger for a broad altcoin rally (Cowen) |
| BTC reaches new all-time highs | Strong BTC leads often precede a broad rotation into altcoins |
| Declining BTC dominance | Indicates Bitcoin’s weakening grip on market capital flows |
| Breakout in TOTAL2/TOTAL3 indices | Technical confirmation that altcoins are expanding |
| Continued institutional inflow | Pushes capital beyond Bitcoin into selective altcoins i |
| Macro Liquidity / Fed Posture | Determines whether external conditions support risky asset flows |
| Retail engagement and momentum | Provides fuel for sustainable movements, especially for mid/small caps |
Conclusion: cautious optimism, no certainty
In short, the market story for the fourth quarter of 2025 shows more optimism around an altseason than ever before this year. The combination of weakening BTC dominance, neutral to improving altcoin momentum, institutional rotations, and shifting macro signals has many analysts and traders convinced that the pieces may finally be aligning.
However, the consensus is far from uniform. Analysts like Benjamin Cowen remind us that important thresholds (especially for Ethereum) must be crossed and held. Others warn that early outbreaks could turn into a false start if there is no broader support. Macro surprises or interest rate policy shocks remain tail risks.
For readers and market participants, the period at the end of 2025 will be crucial. When the outdoor season arrives, much of the foundation needs to be laid from October through December. Even if a large-scale run doesn’t materialize, opportunities could emerge in microcycles, sectoral breakouts, or selective narratives such as AI, infrastructure, or DeFi.
BraveNewCoin’s audience should be aware of both the upside potential and the fragility of the circumstances. A considered, research-based approach can yield the best results – should the fourth quarter prove to be the launching pad for the next altcoin wave.
