Altseason—a thrilling and often lucrative phase in the cryptocurrency market cycle—refers to a period when alternative cryptocurrencies (altcoins) significantly outperform Bitcoin. While Bitcoin remains the dominant force in the crypto world, there are moments when investor attention shifts dramatically toward altcoins, sparking rapid price increases across a wide range of digital assets.
Understanding when altseason starts—and how to recognize its early signals—can offer traders and investors powerful opportunities to capitalize on market momentum. This article explores the three primary drivers indicating that altcoin season has begun, along with practical ways to identify these shifts in real time.
What Is Altseason and Why Does It Matter?
Altseason is not an officially defined period but rather a market phenomenon observed historically during bullish crypto cycles. It typically follows a strong rally in Bitcoin’s price, after which capital begins rotating into altcoins. As confidence grows and FOMO (fear of missing out) intensifies, investors seek higher returns from lesser-known but high-potential projects.
So, when does altseason start? There's no fixed calendar date, but it usually emerges when certain technical and psychological conditions align across the market. Recognizing these signs early can make a significant difference in portfolio performance.
3 Key Indicators That Altcoin Season Has Begun
1. Declining Bitcoin Dominance
One of the most reliable signals of an emerging altseason is a sustained drop in Bitcoin dominance—the percentage of the total cryptocurrency market cap held by Bitcoin.
Historically, when Bitcoin dominance falls below 50%, it indicates that investors are reallocating funds from BTC into alternative cryptocurrencies. In late 2024, for example, Bitcoin dominance dropped by over 7%, creating space for altcoins to gain traction.

This shift doesn’t happen overnight. After Bitcoin completes a major upward move, many traders take profits and redeploy capital into undervalued or underperforming altcoins. As more money flows into Ethereum, Solana, Avalanche, and emerging Layer 1 and Layer 2 ecosystems, the collective altcoin market heats up—marking the beginning of altseason.
2. Surge in Altcoin Market Capitalization
A sharp rise in the total market capitalization of altcoins is another strong indicator of altseason. In late 2024, the altcoin market cap surged past $1.16 trillion, reaching a new all-time high.
This surge reflects growing institutional and retail interest in blockchain innovations beyond Bitcoin. Whether it's DeFi protocols, NFT platforms, or scalable smart contract networks, increasing adoption fuels demand for native tokens.
When altcoins break key resistance levels—such as Fibonacci retracement zones—it often signals strong upward momentum. Traders watch these patterns closely, using them to anticipate further gains and confirm the arrival of altseason.
3. Technological Innovation and Positive Market Sentiment
Technology drives value in crypto. Innovations in decentralized finance (DeFi), non-fungible tokens (NFTs), Web3 infrastructure, and Layer 2 scaling solutions have consistently acted as catalysts for altcoin rallies.
For instance:
- Ethereum’s continued evolution with upgrades like EIP-4844 improves scalability and reduces fees.
- Solana’s resurgence in developer activity and transaction volume has reignited investor confidence.
- Emerging ecosystems like Arbitrum, Optimism, and Base are attracting new projects and users.
These developments generate positive sentiment, which spreads rapidly through social media, crypto forums, and news outlets. As optimism builds, traders increasingly shift focus from Bitcoin to high-growth altcoins—fueling the altseason cycle.
How to Identify Altseason in Real Time
Recognizing altseason as it unfolds requires both technical analysis and macro-level observation. Here are actionable methods to spot the shift:
Monitor Trading Volume
When altcoins consistently show higher trading volumes than Bitcoin, it suggests increased market participation and interest. A spike in volume often precedes price surges.
Analyze Technical Indicators
Tools like:
- Relative Strength Index (RSI): Readings above 70 may indicate overbought conditions—but also strong momentum.
- MACD (Moving Average Convergence Divergence): Bullish crossovers suggest upward trend strength.
Applying these indicators across top altcoins (e.g., ETH, BNB, ADA) helps confirm broader market momentum.
Track Altcoin Performance vs. Bitcoin
Watch BTC/altcoin pairs on trading charts. If multiple altcoins begin outperforming Bitcoin simultaneously—especially in terms of percentage gains—it's a strong sign of altseason.
