The cryptocurrency market is no stranger to dramatic shifts in momentum—and one of the most anticipated phenomena among traders is altcoin season. In November 2024 alone, the total crypto market cap surged by $360 billion, with altcoins contributing nearly 40% of that explosive growth. This surge signals a potential shift in investor focus from Bitcoin to alternative cryptocurrencies, sparking renewed interest in the Altcoin Season Index—a key tool for identifying when altcoins begin to outperform BTC.
Altcoin season, often referred to as “altseason,” occurs when non-Bitcoin cryptocurrencies experience significant price appreciation and increased trading volume, often outpacing Bitcoin’s performance. While Bitcoin remains the market leader, history shows that periods of altcoin dominance can deliver life-changing returns—especially for early movers.
Understanding Altcoin Season: Key Characteristics
Altcoin season is more than just rising prices—it reflects a broader shift in market behavior and sentiment. When altseason takes hold, three major trends typically emerge:
- Soaring Altcoin Prices: Many altcoins see double- or triple-digit gains in weeks, driven by speculative interest and capital rotation from Bitcoin.
- Spike in Trading Volume: As traders seek higher returns, trading activity surges across altcoin markets, increasing liquidity and volatility.
- Shift in Market Sentiment: Investor attention pivots from Bitcoin’s stability to the high-risk, high-reward potential of altcoins.
This dynamic creates a fertile environment for innovation-driven projects and meme coins alike, where even lesser-known tokens can experience meteoric rises.

Altcoin Season vs. Bitcoin Season: A Cyclical Shift
The crypto market moves in cycles, alternating between Bitcoin season and altcoin season. Recognizing these phases helps investors time their entries and exits strategically.
Bitcoin Season: Stability and Institutional Dominance
Bitcoin season is characterized by rapid BTC price growth, increased institutional adoption, and rising market dominance—often exceeding 60%. The recent rally to an all-time high of $93,400 was fueled by multiple catalysts:
- Approval of Bitcoin spot ETFs
- The April 2024 halving event
- Pro-crypto sentiment following the U.S. elections
During this phase, Bitcoin absorbs the majority of trading volume and investor interest, offering a relatively stable environment amid macroeconomic uncertainty.
Altcoin Season: Speculation and High-Growth Potential
In contrast, altcoin season emerges when Bitcoin’s momentum slows and investors begin rotating capital into alternative assets. The 2020–2021 cycle saw altcoin dominance climb from 30% to over 60%, driven by the rise of meme coins like Dogecoin and Shiba Inu, as well as the NFT boom on platforms like Ethereum and Solana.
While riskier due to lower market caps and higher volatility, altseason offers outsized return potential for those who identify promising projects early.
The Altcoin Season Index: How It Works
The Altcoin Season Index is a data-driven tool that measures whether the market is favoring altcoins over Bitcoin. It analyzes the performance of the top 50–100 altcoins relative to BTC over a 90-day period.
Key Components of the Index:
- Relative Performance: If more than 75% of major altcoins outperform Bitcoin, the index signals an active altseason.
- Trading Volume Trends: Rising volume in altcoin pairs indicates growing demand and market participation.
- Market Dominance Shifts: A declining Bitcoin dominance (below 50%) often precedes or confirms altcoin season.
How to Interpret the Index:
- Above 75%: Strong confirmation of altcoin season
- 25%–75%: Mixed market—both BTC and altcoins showing strength
- Below 25%: Bitcoin dominance remains intact
As of late 2024, the index hovers around 35%, suggesting that while altcoins are gaining traction, Bitcoin still controls market momentum.
Popular platforms like Blockchain Center and CoinMarketCap offer real-time tracking of the Altcoin Season Index, complete with historical charts and performance metrics.

Historical Altcoin Seasons: Lessons from the Past
Examining past cycles reveals patterns that could shape the future of altseason.
2017–2018: The ICO Boom
The first major altseason was driven by the Initial Coin Offering (ICO) frenzy. Ethereum’s price skyrocketed from $8 to over $1,400, becoming the foundation for hundreds of new tokens. Projects like EOS raised over $4 billion through ICOs. However, regulatory scrutiny and failed deliverables led to a sharp correction by 2018.
2020–2021: Meme Coins and NFT Mania
Low interest rates and pandemic-era stimulus fueled speculative investing. Dogecoin surged from under $0.01 to $0.60, while Shiba Inu gained millions of holders. Simultaneously, NFTs on Ethereum and Solana drove ecosystem growth, reinforcing platform coins’ value.
These cycles show that altseason often follows Bitcoin’s peak—creating a “spillover effect” where traders chase higher returns in alternative assets.
Signs That Altcoin Season Is Approaching
While no single indicator guarantees altseason, several signals suggest it may be on the horizon:
- Declining Bitcoin Dominance: A drop below 50% often precedes widespread altcoin rallies.
- Rising Altcoin Trading Volumes: Increased activity on SOL, AVAX, and SHIB pairs signals growing interest.
- Price Breakouts: Sustained moves above resistance levels in major altcoins reflect building momentum.
- Shifts in Investor Behavior: Retail traders and “smart money” reallocating from BTC to alts is a strong leading indicator.
Why 2025 Could Be the Next Altcoin Season
Several macroeconomic and market factors point to a potential altseason in 2025:
- Bitcoin’s Price Stabilization: After reaching $93,400, BTC may enter a consolidation phase—historically a precursor to altseason.
- Ethereum ETF Approvals: The launch of spot Ethereum ETFs in 2024 could unlock institutional capital, creating a ripple effect across other altcoins.
- Federal Reserve Rate Cuts: Expected interest rate reductions in 2025 may push investors toward high-growth assets like crypto.
- Pro-Crypto Regulatory Shifts: A favorable policy environment in the U.S., including support for blockchain innovation, could boost market confidence across all digital assets.

Frequently Asked Questions (FAQ)
When does altcoin season start?
Altcoin season has no fixed schedule. It typically begins after Bitcoin consolidates following a major rally, prompting investors to seek higher returns in alternative assets.
What happens to Bitcoin during altcoin season?
Bitcoin’s price growth often slows, and its market dominance may decline as capital flows into altcoins. However, BTC usually remains stable rather than crashing.
How do I know which altcoins are gaining momentum?
Monitor price action, trading volume spikes, and social sentiment on platforms like CoinMarketCap or CoinGecko. Coins showing sustained volume increases are often primed for breakout.
Can small-cap altcoins outperform during altseason?
Yes—small-cap altcoins often deliver the highest percentage gains due to their low entry prices and high speculation. However, they come with greater risk.
Is altcoin season guaranteed every cycle?
No—while historically recurring, altseason depends on market conditions, investor sentiment, and macroeconomic factors. It’s not automatic after every Bitcoin rally.
How long does altcoin season last?
It varies—past cycles have lasted from several weeks to over six months. Duration depends on liquidity flow, regulatory news, and broader market trends.
