With renewed macro 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 & Sentiment
In recent months, Bitcoin has held firm around critical support levels after 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 higher. The fact that cryptocurrencies have resumed upward momentum in broader sentiment indicators hints at growing appetite for risk assets again.
One key measure that enthusiasts use is the Altcoin Season Index (ASI), which quantifies how much altcoins are outperforming Bitcoin. According to CoinDCX, the ASI has reached neutral territory — not yet a confirmed “altseason,” but improving steadily — with Ethereum leading recent gains. Meanwhile, BTC dominance (the share of Bitcoin’s market cap relative to the rest) is showing signs of erosion, which historically signals capital rotation into altcoins.
Another telling data point: recent studies show that about 90% of Binance-listed altcoins are trading below their long-term trend lines. While that paints a picture of broad weakness, some analysts interpret it as a potential entry setup – markets often rebound sharply when widespread capitulation gives way to renewed buying.
On the macro front, one catalyst that many watchers cite is the recent tone from the U.S. Federal Reserve. In a recent speech, Fed Chair Jerome Powell indicated that no surprise rate hikes were expected and hinted that balance sheet contraction (quantitative tightening) might ease. That shift in tone is being viewed as a possible precursor to renewed liquidity flowing into risk assets — first to Bitcoin, then Ethereum, and finally to altcoins.
Overall, market participants are increasingly asking: will Q4 2025 finally usher in a sustained altseason?
What Analysts Are Saying
Benjamin Cowen & the $5K ETH Threshold
Crypto analyst Benjamin Cowen remains one of the more vocal skeptics when it comes to premature altseason calls. In his view, for altcoins to meaningfully rally, Ethereum must first break above and hold the $5,000 level. If ETH can’t sustain that as support, any broad altcoin rally would be fragile at best.
Cowen also forecasts 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 then have space to accelerate. But if BTC fails to break convincingly higher or loses key support, any altseason might fizzle.
Bitwise & Institutional Flows
From the institutional vantage point, analysts at Bitwise have flagged several altcoins — Ethereum, Solana, Avalanche, Chainlink, and XRP — as poised to see meaningful inflows in Q4. Their thesis rests on improving regulatory clarity (particularly for U.S. explanations of spot ETPs), growing institutional allocations to tokenization / DeFi themes, and a broader push beyond Bitcoin-only portfolios.
Bitwise’s argument hinges on the idea that institutional capital already migrating into crypto will not stay siloed in Bitcoin forever — sooner or later, portfolio managers will chase higher upside in well-positioned altcoins.
The “Breakout” Camp & Declining BTC Dominance
Other analysts are watching for technical breakouts in indices that track altcoins excluding Bitcoin. One recent article stated that the “TOTAL2” index (market cap of cryptos excluding Bitcoin) is approaching prior highs, and if it breaks decisively, it could trigger a strong altcoin rally.
Crypto Rover, quoted there, also notes that Bitcoin dominance is weakening and not strongly rejecting resistance levels — a classic warning that capital may shift.
Moreover, CCN recently published that Ethereum’s gains versus Bitcoin have already begun to erode BTC dominance. Combined with bullish crossovers in technical momentum indicators, they suggest we might already be in the early stages of altseason.
That said, some opponents warn of false starts. As one Medium author put it, markets can spike in altcoin strength briefly — only for the momentum to fade and revert. Many altcoins still sit far below prior all-time highs, and retail has not fully engaged yet.
Macro-Liquidity Cycles & Global Flow
The “liquidity narrative” is another thread underpinning these expectations. A crypto-focused analysis argues that global liquidity typically leads crypto markets by roughly a 13-week lag, and that global liquidity is expected to peak around Q4 2025. If that holds, it may offer a favorable backdrop for altcoins.
Yet, it’s worth noting that while global liquidity may improve, the U.S. central bank is still relatively constrained. Slowing QT is not the same as reentering aggressive easing. Thus, timing and magnitude of the spillover into risk stances remain uncertain.
What Could Go Wrong (Risks & Counterarguments)
-
BTC dominance snapback. If Bitcoin regains dominance, capital might rotate back into BTC, delaying or muting 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 hold gains.
-
Rate shocks / macro surprises. A hawkish Fed surprise or geopolitical shock could drain risk appetite and derail speculative flows entirely.
-
Retails’ absence. True altseasons often require retail FOMO to amplify momentum. If retail doesn’t jump in, upside may remain limited.
-
Overcrowded narratives. Many altcoin narratives (AI tokens, memecoins, layer-2s) are already crowded; valuations may be frothy or vulnerable to sharp pullbacks.
Roadmap: What to Watch in Q4
Here are key signals and events to monitor:
| Signal / Event | Why It Matters |
|---|---|
| Ethereum breaks and holds $5,000 | Seen by many as a necessary trigger for altcoin broad rally (Cowen) |
| BTC making new all-time highs | Strong BTC leads often precede broad rotation into altcoins |
| Declining BTC dominance | Indicates weakening grip of Bitcoin over market capital flows |
| Breakout in TOTAL2 / TOTAL3 indices | Technical confirmation that altcoins are entering expansion |
| Continued institutional inflows | Pushes capital beyond Bitcoin into selective altcoins i |
| Macro liquidity / Fed posture | Determines whether external conditions support risk asset flows |
| Retail engagement & momentum | Drives fuel for sustained moves, especially for mid/small caps |
Conclusion: Cautious Optimism, Not Certainty
In sum, the market narrative for Q4 2025 holds more optimism around an altseason than at any point this year. The combination of weakening BTC dominance, neutral-to-improving altcoin momentum, institutional rotations, and shifting macro signals has convinced many analysts and traders that the pieces may finally be aligning.
However, consensus is far from uniform. Analysts like Benjamin Cowen remind us that key thresholds (especially for Ethereum) must be passed and held. Others caution that early breakouts might devolve into false starts if broader support is lacking. Macro surprises or rate policy shocks remain tail risks.
For readers and market participants, the late 2025 window will be pivotal. If altseason is to arrive, much of the groundwork must be laid in October through December. Even if a full-scale run fails to materialize, opportunities could emerge in micro-cycles, sectoral breakouts, or selective narratives like AI, infrastructure, or DeFi.
BraveNewCoin’s audience should lean in with awareness of both the upside potential and the fragility of the conditions. A measured, research-driven approach may yield the best results — should Q4 prove to be the launching pad for the next altcoin surge.
