Altcoin Season

Altcoin season (alt season) is a phase in the crypto market cycle when altcoins significantly outperform Bitcoin, often producing 5-50x returns as speculative capital rotates from Bitcoin into smaller coins.
Altcoin season describes the period in a bull market cycle when altcoins dramatically outperform Bitcoin. Capital that accumulated in BTC during the early bull phase rotates into higher-risk, higher-reward altcoins.
How alt season typically unfolds: 1. Bitcoin leads the bull market, making new all-time highs 2. Large-cap altcoins (ETH, SOL, BNB) start outperforming BTC 3. Mid-cap DeFi and infrastructure tokens rally 4. Small-cap altcoins and meme coins surge, often 10-50x 5. Retail investors flood in chasing gains — this is usually the top
Key signals that alt season is underway: - Bitcoin dominance dropping below 50% (or declining trend) - Altcoin/BTC pairs breaking out on charts - Fear and Greed Index at "Extreme Greed" - New all-time highs for total altcoin market cap (excluding BTC and ETH)
Alt season risk: the same speculative energy that drives 50x gains can evaporate quickly. Most altcoins give back 80-95% in the subsequent bear market. Having an exit strategy is essential.

Frequently Asked Questions
How long does altcoin season last?
Historically 2-6 months during bull market cycles. It typically peaks when retail FOMO is at maximum, often shortly before the overall market top. It ends quickly — gains can evaporate in weeks.
How do I know if altcoin season has started?
Watch Bitcoin dominance — when it starts declining from 55%+ and altcoin/BTC pairs are breaking out, alt season may be beginning. The Altcoin Season Index (tracked on sites like Blockchaincenter.net) also measures this.
