Bitcoin dominance declines, meaning altcoins capture a greater share of total market value.
Trading volumes for altcoins surge, often driven by hype, new projects, or sector trends like memecoins and AI tokens.
The Altcoin Season Index climbs above 75, indicating that over 75% of top altcoins have outperformed BTC over the past 30–90 days.
🔍 Is Altseason Already Underway?
Indicators say: Not yet.
Bitcoin dominance is still high—hovering around 62–65% as of mid‑2025.
The Altcoin Season Index remains low, around 26–28, far below the 75 threshold needed to confirm altseason.
Although the ETH/BTC ratio has recently bounced off a multi-year low (from ~0.018 to ~0.025), it hasn't yet broken decisively upward.
🔄 Why Experts Say Altseason May Be Near
Historical patterns and cycle-based analysis suggest possible timing:
Past altseasons occurred several hundred days after a Bitcoin halving. One model estimates the next altseason to begin around December 10, 2024, and run through mid‑October 2025.
TechDev and other analysts believe altcoins gain momentum once BTC dominance peaks and ETH starts catching up.
Market shifts in February–March 2025 mirrored earlier cycles, with BTC dominance spiking and then easing—hinting the rotation may be starting.
➡️ At present, altseason hasn’t truly begun—most reliable indicators show we're still in Bitcoin season. That said, early signs of a shift are emerging, with historical analogues suggesting a rotation could be underway or imminent.
