Alt season is now established as Altcoin Season Index crosses 78, with board-wide bull runs in the top performing altcoins. ASTER, ZEC, PUMP, and FTT all registered double-digit percentage gains, which signaled new investor control across the board.
Altcoin Season Officially Established as Index Reaches 78
The Altcoin Season Index reached 78, the 75-point threshold to validate an altseason. This threshold was last seen late in 2024.

Spike is an outcome of increased investor rotation from Bitcoin to altcoins. DeFi, meme, and AI tokens are experiencing the largest flows. The index tracks 50 altcoins against BTC for 90 days. Any figure above 75 indicates that the majority of the alts are beating BTC, verifying a good season trend.
ASTER, ZEC, PUMP: Top Altcoin Gainers Leaders
A number of tokens surged strongly as altcoin strength gained momentum:
- ASTER jumped 4.2% in 24 hours and 19% within a week. It was also the largest DeFi gainer that was not stable and topped DeFi in protocol revenue at $7.12 million.
- Zcash (ZEC) pumped by over 13% intraday. Open interest rose 39% to $19.04 million, showing rising trader optimism.
- Pump.fun (PUMP) recovered essential technical support and saw its long-to-short ratio climb from 49.71% to 52.78%, a bullish sign.
This is due to capital flows and technical breaches-induced gains surge in mid-cap and low-cap altcoins.

FTT Token Pumps After Mysterious “gm” Tweet
FTT, the official token of FTX, jumped over 32% after a quick “gm” post on Sam Bankman-Fried’s verified X account.
Daily volume rose from $10.4 million to nearly $59 million even with SBF already under arrest. The subsequent post made it clear that it was actually from a friend, not Bankman-Fried.

The post did create a wave of speculative buying, which took the price of FTT well past significant levels. This shows that market participants continue to react violently to news based on stories in the altcoin space.
What This Means for Q4 2025
The validated alt season means Q4 2025 will see altcoin price appreciation across the board. Capital will continue to flow into momentum and social tokens.
Altcoins, especially DeFi, AI, and meme coins, are already beating and leading Bitcoin, which continues to serve as the benchmark for now. Investors should be on the lookout for a firm entrenched technical basis and a shift in sentiment as altseason is experienced.
