Has altcoin season 2026 started yet?

As of Q2/2026, BTC dominance is around 55-58% — not low enough for a clear altcoin season. Historical patterns show altcoin season usually arrives 6-12 months after BTC's peak. The April 2024 halving sets a peak window of April 2025 to October 2026; altcoin season could explode in late 2026 or early 2027.

What are the signs that altcoin season is about to start?

Four signs: (1) BTC dominance drops below 55% and breaks its uptrend; (2) The ETH/BTC ratio rises above 0.06; (3) Top altcoins (SOL, BNB, AVAX) outperform BTC for 2-3 consecutive weeks; (4) The Altcoin Season Index (Blockchain Center) exceeds 75/100. When all four appear simultaneously, it's a strong signal.

Altcoin season 2026 strategy?

Gradually rotate from BTC: (1) Start with 70% BTC, 20% ETH, 10% top alt when BTC dominance is high; (2) When dominance drops to ~55%, shift to 50% BTC, 30% ETH, 20% top alt; (3) When the alt season Index is above 90, sell altcoins in portions. Avoid: buying mid-caps while dominance is still high — they will only bleed against BTC.
