What changed

Bitcoin strengthened against the broader market this week: it rose 2.4% while BTC dominance increased 0.6 percentage points to 58.8%. That matters more for rotation than the higher Season Index, which gained 5 points to 61 but remains below the 75 threshold where this tracker defines altcoin season. Total market cap rose 1.6% to $2.94T, yet only 24 of 50 tracked altcoins beat Bitcoin over 7 days, showing that market growth was not broad altcoin leadership. QNT, BTW and PUMP posted the strongest relative performance, while M, ZEC and VVV lagged sharply. Community discussion centered on stablecoin exchange dominance, regulation, exploits and launch liquidity—topics consistent with a market focused on liquidity access and risk rather than broad risk-taking.

Key insights

  1. Index improvement has not become rotation

    The 90D Season Index rose 5 points to 61/100, but it is still below the 75 level that marks altcoin season. At the same time, BTC dominance rose to 58.8%, moving away from the below-42% rotation condition.

  2. Breadth favored Bitcoin

    Just 24 of 50 tracked altcoins outperformed Bitcoin over 7 days. Bitcoin’s 2.4% weekly gain exceeded total market cap growth of 1.6%, reinforcing that leadership was concentrated in BTC rather than distributed across alts.

  3. Relative winners were highly selective

    QNT led the tracked group against Bitcoin at +162.8%, followed by BTW at +51.1% and PUMP at +46.8%. The dispersion extended lower as well: M fell 15.0% versus BTC, ZEC fell 13.1%, and VVV fell 12.5%.

  4. Community focus fits a selective market

    Stablecoin exchange-dominance claims appeared in 2 of 7 daily briefings, while regulatory scrutiny, the NEAR Intents exploit, wallet-security risks and launch-liquidity structures each drew attention. That focus agrees with the data’s narrow leadership, although adoption skepticism sits uneasily beside a higher total market cap.

Scenarios for the week ahead

Bull case

Confirmed if The Season Index reaches 75 and BTC dominance moves below 42%.

That combination would confirm that the improving index has developed into the tracker’s defined altcoin season. Broader altcoin outperformance would need to accompany the shift rather than remain concentrated in a few names.

Base case

Confirmed if The Season Index holds around or above 61 while BTC dominance stays near or above 58.8%.

This would describe continued improvement in altcoin conditions without a confirmed capital rotation. Bitcoin would remain the market’s primary leader while selected alts produce outsized relative moves.

Bear case

Confirmed if BTC dominance rises above 58.8% and fewer than 24 of 50 tracked altcoins beat Bitcoin over 7 days.

That would signal a further narrowing of participation toward Bitcoin. The index’s latest gain would look less durable if breadth weakens alongside rising BTC share.

Outlook

The central question is whether the Season Index’s rise to 61 can translate into broader relative strength while BTC dominance reverses. For now, the data favors a Bitcoin-led market: dominance rose, Bitcoin outpaced total market-cap growth, and fewer than half of tracked alts beat BTC. Community attention on stablecoin concentration, exchange regulation, exploits and launch liquidity supports a cautious, selective backdrop. A move toward the 75 index threshold and below-42% BTC dominance would materially change that reading.
