The cryptocurrency market moves in cycles, and one of the most anticipated phases for investors is the Altcoin Season—a period when alternative cryptocurrencies (altcoins) outperform Bitcoin in terms of price growth. With the Bitcoin Halving occurring in April 2024 and increasing institutional adoption through ETFs, speculation is building about whether an Altcoin Season could emerge in late 2024 or early 2025. In this comprehensive guide, we’ll explore what defines an Altcoin Season, its historical patterns, key indicators like Bitcoin Dominance, and what to expect in the coming months.
What Is an Altcoin Season?
An Altcoin Season, often referred to as "Altseason," is a market phase during which altcoins experience significantly higher returns compared to Bitcoin. During this time, capital flows from Bitcoin into a wide range of alternative digital assets such as Ethereum, Solana, Cardano, and emerging sector-specific tokens like AI coins and DeFi tokens.
A key indicator of an Altcoin Season is the decline in Bitcoin Dominance (BTC.D)—the percentage of Bitcoin’s market capitalization relative to the total crypto market. When BTC.D drops, it signals that investors are reallocating funds into altcoins, driving up their collective value.

While Bitcoin often leads the bull market with strong early gains, altcoins tend to surge later—delivering exponential returns for those who time the shift correctly.
The Bitcoin Cycle and Altcoin Seasons
Altcoin Seasons don’t happen randomly. They are deeply connected to the Bitcoin market cycle, which typically follows these stages:
1. Early Bull Market Phase
After a prolonged bear market or consolidation period, Bitcoin begins to rally. New capital enters the ecosystem, primarily flowing into Bitcoin due to its reputation as a "safe haven" within crypto. During this phase:
- Bitcoin price rises steadily.
- Bitcoin Dominance remains high or even increases.
- Altcoins generally underperform.
This stage usually follows major catalysts like halvings or regulatory clarity (e.g., spot Bitcoin ETF approvals in 2024).
2. Mid-Bull Market Phase
Bitcoin breaks past previous all-time highs, attracting media attention and retail interest. Early investors start taking profits.
- Momentum builds across the market.
- Some altcoins begin to show strength.
- Bitcoin still dominates headlines and inflows.
At this point, experienced traders may begin rotating部分 positions into high-potential altcoins.
3. Late Bull Market Phase
Bitcoin's price growth starts to slow as it approaches its peak. Investor sentiment reaches euphoria.
- Profit-taking accelerates.
- Capital rotates into riskier but higher-growth assets—altcoins.
- Bitcoin Dominance begins to fall sharply.
- Altcoin Season intensifies.
Historically, this is when smaller-cap altcoins deliver 5x, 10x, or even 50x returns in just weeks.
4. Market Top & Correction
Once Bitcoin peaks and enters a correction or sideways phase, investor focus shifts almost entirely to altcoins.
- Altcoins reach their highest momentum.
- FOMO (fear of missing out) drives speculative activity.
- New investors enter via trending altcoins.
This final leg often marks the height of the Altcoin Season—before the broader market eventually turns bearish again.
How Long Does an Altcoin Season Last?
On average, an Altcoin Season lasts between 6 to 9 months. However, the most explosive gains typically occur in the last 4 to 8 weeks, making timing crucial for maximizing returns.
Let’s look at historical examples:
Altcoin Season 2017–2018
Following the 2016 halving, Bitcoin surged throughout 2017. By December 2017, it hit nearly $20,000. Shortly after:
- Bitcoin Dominance dropped from over 85% to around 32% by early 2018.
- Projects from the ICO boom—Ethereum, Ripple, Litecoin—skyrocketed.
- The biggest moves happened in the four weeks after Bitcoin’s peak, when capital flooded into altcoins.
Altcoin Season 2021
After Bitcoin’s post-halving rally in late 2020 and early 2021:
- BTC.D fell from over 70% to about 40% by May 2021.
- DeFi tokens (e.g., UNI, SUSHI), Ethereum, and newer layer-1 blockchains like Solana led gains.
- The strongest performance occurred over an 8-week window from March to May.
These patterns suggest that while the Altcoin Season unfolds gradually, its climax comes quickly—and catching that window can make a significant difference in portfolio returns.
Key Indicators: Bitcoin Dominance and Beyond
Understanding Bitcoin Dominance
Bitcoin Dominance measures BTC’s share of the total cryptocurrency market cap. It’s calculated as:
BTC Market Cap ÷ Total Crypto Market Cap × 100
It serves as a powerful signal:
- Rising BTC.D: Capital favors Bitcoin; altcoins likely stagnating.
- Falling BTC.D: Money is moving into altcoins—potential Altcoin Season underway.
However, raw dominance can be misleading due to the growing influence of stablecoins like USDT and USDC.
Adjusted Metrics for Better Insight
🔹 BTC.D Minus Stablecoins
By excluding stablecoins from the total market cap calculation, analysts get a clearer view of real investor behavior between volatile assets.
- This adjusted metric highlights actual shifts between Bitcoin and other cryptos.
- A drop in this version of BTC.D strongly suggests genuine altcoin strength—not just stablecoin expansion.
🔹 BTC vs. Top 10 Altcoins
Another useful filter removes the largest altcoins (Ethereum, BNB, Solana, etc.) to assess Bitcoin’s position against mid- and small-cap projects.
- Helps identify opportunities beyond blue-chip altcoins.
- Reveals whether momentum is spreading deep into the market cap ranks.
👉 Monitor real-time dominance trends and spot early signs of an incoming Altcoin Season.
Sector-Based Analysis: Where Could Gains Emerge?
Instead of viewing all altcoins as one group, savvy investors analyze performance by crypto sectors. Here are some high-potential categories to watch:
- Layer-1 Blockchains
Foundational networks like Solana, Avalanche, and Polkadot that support dApps and smart contracts.
- DeFi (Decentralized Finance)
Protocols enabling lending, borrowing, and trading without intermediaries (e.g., Aave, Uniswap).
- AI + Blockchain Integration
Tokens powering AI-driven blockchain platforms (e.g., Fetch.ai, SingularityNET).
- Web3 & Identity
Projects focused on decentralized identity, data ownership, and user-controlled internet experiences.
- Metaverse & Gaming
Virtual worlds and play-to-earn ecosystems built on blockchain (e.g., MANA, GALA).
- Meme Coins
Highly speculative assets driven by community and social media trends (e.g., Dogecoin, Shiba Inu).
Tracking BTC’s performance relative to baskets of coins in each sector can reveal which areas are heating up first.
Will There Be an Altcoin Season in 2024 or 2025?
Based on historical patterns and current developments, there is strong potential for an Altcoin Season in late 2024 or early 2025.
Key catalysts include:
- ✅ Bitcoin Halving (April 2024): Reduced supply inflation historically precedes major bull runs.
- ✅ Spot Bitcoin ETF Approvals (January 2024): Institutional demand has increased significantly.
- ✅ Growing Macro Acceptance: More companies and governments exploring crypto integration.
After Bitcoin completes its primary bull run phase—likely peaking in late 2024 or early 2025—investors are expected to take profits and rotate capital into altcoins.
This capital rotation sets the stage for a broad-based rally across the altcoin market, especially among projects with strong fundamentals and real-world use cases.
Where to Buy Altcoins Safely
Choosing a secure and reliable exchange is essential for participating in an Altcoin Season. Look for platforms with:
- Strong security protocols
- Regulatory compliance
- Wide selection of tradable assets
- User-friendly interface
While many exchanges offer hundreds of altcoins, not all prioritize safety. Regulated platforms with European licenses provide added peace of mind for long-term investors.
👉 Access a global selection of altcoins with advanced trading tools and robust security.
Frequently Asked Questions (FAQ)
How long does an Altcoin Season last?
An Altcoin Season typically lasts between 6 and 9 months, with the most significant price surges occurring in the final 4 to 8 weeks as investor sentiment reaches peak optimism.
Why are Altcoin Seasons linked to the Bitcoin cycle?
Because Bitcoin usually leads the bull market, drawing initial investment. Once its price stabilizes or corrects after reaching highs, traders take profits and move capital into altcoins seeking higher short-term returns—triggering the Altcoin Season.
How is Bitcoin Dominance calculated?
Bitcoin Dominance is calculated by dividing Bitcoin’s market capitalization by the total market cap of all cryptocurrencies, then multiplying by 100 to get a percentage. It reflects BTC’s weight in the overall crypto economy.
Why adjust Bitcoin Dominance for stablecoins?
Stablecoins make up a large portion of the total market cap but don’t reflect speculative investment. Removing them gives a clearer picture of how Bitcoin performs against other volatile digital assets like ETH or SOL.
Can an Altcoin Season happen before Bitcoin peaks?
It’s rare. Most significant altcoin rallies occur after Bitcoin has already achieved substantial gains and begins to stabilize or consolidate. Premature altcoin rallies often lack staying power without broader market momentum.
What are early signs of an upcoming Altcoin Season?
Watch for:
- Declining Bitcoin Dominance
- Increasing volume in altcoin pairs
- Strong performance in major altcoins like Ethereum and Solana
- Rising interest in niche sectors like AI or DePIN
Final Outlook: Preparing for the Next Altseason
With the 2024 Bitcoin Halving behind us and institutional adoption accelerating, the foundation is being laid for a powerful market cycle. While Bitcoin will likely lead the charge initially, the spotlight will eventually shift to altcoins.
Smart investors prepare ahead of time by:
- Researching high-potential projects across emerging sectors.
- Monitoring BTC.D and adjusted dominance metrics.
- Staying alert for signs of profit-taking in Bitcoin markets.
Whether you're new to crypto or a seasoned trader, understanding the rhythm of the market cycle—and knowing when an Altcoin Season may begin—can help you make more informed decisions and potentially capture outsized gains.
Stay strategic, stay informed, and be ready when the next wave hits.
