What is the Altcoin Season: Understanding the Market Trends from the End of 2024 to 2025

At the beginning of 2026, the cryptocurrency market is entering a new phase. Central to this is the phenomenon known as “Altcoin Season.” Altcoin season refers to the period when investments in altcoins outperform Bitcoin, marking the most exciting phase in the market cycle. Along with the market’s evolution over recent years, the nature of altcoin season has also undergone significant changes. What was once a simple transfer of capital has now developed into a more complex, multi-layered phenomenon supported by liquidity from stablecoins and the entry of institutional investors, reflecting a more mature market environment.

The Interrelationship Between Altcoin Season and the Bitcoin Market

The first step to understanding altcoin season is to grasp the pattern of capital flows within the market. Traditionally, altcoin season was characterized by a large transfer of capital from Bitcoin to other altcoins. When Bitcoin’s price rose and investors took profits, they shifted funds into altcoins seeking higher returns—a straightforward mechanism.

However, as Ki Young Ju, CEO of CryptoQuant, points out, this mechanism has fundamentally changed. Currently, altcoin season is driven not by direct movement of trading volume from Bitcoin pairs, but by an increase in altcoin trading volume in stablecoin pairs such as USDT and USDC. This shift indicates that the phenomenon is not just a market trend but reflects the full-scale entry of institutional investors and the development of market infrastructure, suggesting a more mature environment.

Evolution of Altcoin Season: Toward the Era of Stablecoins

The biggest difference between past and present altcoin seasons lies in the source of liquidity.

During the ICO boom from late 2017 to early 2018, altcoin season was defined by speculative enthusiasm for emerging projects like Ethereum, Ripple, and Litecoin. During this period, Bitcoin’s dominance dropped sharply from 87% to 32%, and the total market capitalization of cryptocurrencies expanded from $30 billion to $600 billion. However, increased regulation and project failures quickly ended this prosperity.

The altcoin season of early 2021 presented a different picture. Altcoins related to DeFi, NFTs, and meme coins were heavily bought, pushing the overall market cap to a record high of $3 trillion. During this time, Bitcoin’s dominance fell from 70% to 38%, while the market share of altcoins doubled from 30% to 62%.

The current altcoin season, from late 2024 to early 2025, differs from these past examples. It is influenced by multiple factors, including the approval of spot Bitcoin and Ethereum ETFs, expectations of a pro-crypto stance under the Trump administration, and the passage of time since the Bitcoin halving in April 2024. Simultaneously, the liquidity provided by stablecoins has made the altcoin market more accessible to a broad range of participants, from individual investors to institutions.

Sector Diversification: From AI to Metaverse

While past altcoin seasons focused on specific trends like ICOs or DeFi, today’s altcoin season spans multiple sectors.

The rise of AI-related projects is a prime example. Decentralized AI infrastructure projects such as Render (RNDR) and Akash Network (AKT) have surged over 1000%. This growth reflects high market expectations for integrating AI into the crypto ecosystem.

At the same time, GameFi platforms like ImmutableX (IMX) and Ronin (RON) show signs of revival, rekindling interest in blockchain gaming. Additionally, meme coins (DOGE, SHIB, BONK, PEPE) are evolving from mere speculative assets into projects that incorporate AI and utility features, adding substance.

The Solana ecosystem’s activity is particularly notable. Solana-based meme coins have gained popularity, helping to dispel the label of “dead chain,” with token prices increasing by 945%, significantly boosting the ecosystem’s presence in the market.

Four Indicators to Signal the Arrival of Altcoin Season

Investors need to recognize concrete signs of altcoin season to make effective decisions. Here are key indicators market participants should monitor:

Indicator 1: Decline in Bitcoin Dominance

Historically, when Bitcoin dominance falls below 50%, it signals the onset of altcoin season. According to Rekt Capital, a blockchain analytics firm, if Bitcoin remains in a range of $91,000 to $100,000, conditions become favorable for altcoins like Ethereum to absorb liquidity, making a decline in dominance more likely.

Indicator 2: Rise in ETH/BTC Ratio

The price ratio of Ethereum to Bitcoin serves as a barometer for the overall health of the altcoin market. An increasing ETH/BTC ratio indicates Ethereum is outperforming Bitcoin, often preceding broader altcoin market rallies. Conversely, a declining ratio suggests Bitcoin strength and a risk-averse sentiment.

Indicator 3: Blockchain Center’s Alt Season Index

This index quantifies the performance of the top 50 altcoins relative to Bitcoin. Readings above 75 indicate the arrival of altcoin season. As of early 2025, the index reaching 78 suggests the market is already within altcoin season territory.

Indicator 4: Increased Stablecoin Liquidity and Trading Volume

Rising liquidity in stablecoins like USDT and USDC, along with increased trading volume in altcoin pairs, signals genuine market participation rather than mere speculation. Significant trading activity in specific sectors (AI, meme coins) provides crucial clues about where market interest is concentrated.

The Impact of Institutional Investors and Bitcoin Spot ETFs

According to Tom Lee, analyst at Fundstrat, the entry of institutional investors into the altcoin market is a key factor distinguishing this altcoin season from previous ones.

Approval of over 70 spot Bitcoin ETFs has accelerated institutional inflows into the crypto market. This trend extends beyond Bitcoin, encouraging diversification into major altcoins like Solana and Ethereum. Institutional appetite for high-risk altcoin investments has significantly improved market liquidity and made access easier for retail investors.

Regulatory improvements and the rise of policymakers with pro-crypto stances further accelerate this trend. Clear legal frameworks and openness from major regulatory agencies foster positive market sentiment, increasing the likelihood of an extended altcoin season.

Practical Trading Strategies During Altcoin Season

Success in altcoin season requires a systematic approach.

Strategy 1: Gradual Position Building

Instead of investing all funds at once, incrementally increase positions across multiple market phases. This reduces risk from market volatility and helps achieve better average entry prices.

Strategy 2: Sector Diversification and Coin Selection

Diversify across sectors such as AI, GameFi, meme coins, and metaverse projects. Relying too heavily on a single trend can lead to significant losses if sentiment shifts. Conduct thorough fundamental analysis of projects, including team quality, utility, and development progress, before investing.

Strategy 3: Combining Technical Indicators and Sentiment Analysis

Use quantitative data like Bitcoin dominance, ETH/BTC ratio, and Alt Season Index alongside qualitative insights such as social media trends and market psychology. This integrated approach enhances decision-making accuracy.

Strategy 4: Profit Taking and Loss Prevention

Given the high volatility, it’s crucial to take profits incrementally and set stop-loss orders to limit potential losses. Focus on consistent gains rather than expecting overnight riches, as sustainable success depends on disciplined profit management.

Risk Management: Five Common Pitfalls in Altcoin Season

While altcoin season is exciting, it carries inherent risks:

Risk 1: Underestimating Volatility

Altcoins are far more volatile than Bitcoin, with 50% price swings in short periods being common. Without proper risk controls, profits can evaporate quickly. Low liquidity altcoins often have wide spreads, increasing trading costs.

Risk 2: Excessive Leverage and Speculation

Using high leverage in margin or derivatives trading amplifies both gains and losses. During altcoin season, speculative fervor can tempt traders to take on risky positions. Maintaining conservative leverage and position sizes is essential.

Risk 3: Scams and Pump-and-Dump Schemes

As interest surges, so do scams like rug pulls and pump-and-dump schemes. Investing in unknown projects requires thorough due diligence and caution.

Risk 4: Sudden Regulatory Changes

Regulatory environments can change unexpectedly. Pro-crypto policies may reverse, causing market shocks. Monitoring regulatory news is vital to avoid surprises.

Risk 5: Missing the End of the Cycle

Altcoin season is finite. Market sentiment peaks and then reverses, leading to capital outflows and sharp declines in many altcoins. Early detection of signs like rising Bitcoin dominance, declining Alt Season Index, and waning social media buzz is crucial for timely position adjustments.

Learning from the Past: Altcoin Cycle Analysis

Historical market cycles offer valuable insights:

The first major altcoin season in late 2017 to early 2018 saw Bitcoin dominance plummet from 87% to 32%. The ICO boom led to thousands of new projects, pushing total market cap from $30 billion to over $600 billion. However, regulatory crackdowns and project failures caused a rapid collapse in 2018.

The 2021 altcoin season was more sophisticated, driven by DeFi, NFTs, and meme coins, with market cap reaching $3 trillion. Ethereum, Solana, and Cardano benefited significantly. Yet, this exuberance transitioned into the 2022 crypto winter.

The current cycle, from late 2024 into 2025, differs by featuring institutional participation, ETF-driven inflows, and sector diversification (AI, GameFi, Metaverse). It is built on real technological advancements and practical use cases, not just speculation.

Why Now Is the Time to Watch for Altcoin Season

As of early 2025, several structural factors support the anticipation of a full-blown altcoin season:

1. Maturation of ETF Infrastructure

Beyond Bitcoin ETFs, approval of spot Ethereum ETFs and potential future altcoin ETFs will open new capital channels. Institutional investors can access altcoins directly through traditional brokerage accounts, bypassing crypto exchanges.

2. Geopolitical and Political Factors

Expectations of pro-crypto policies under new governments can boost market confidence and regulatory clarity.

3. Accelerating Technological Innovation

Emerging sectors like AI, Metaverse, and DePIN are entering growth phases, each offering unique investment opportunities in specific altcoins.

4. Increased Market Maturity

Participants with more experience and better information are reducing irrational exuberance, leading to more stable and sustainable altcoin cycles.

Preparing for Altcoin Season: Practical Steps

Investors aiming to participate should undertake thorough preparation:

Step 1: Education and Research

Deeply investigate projects before investing—review whitepapers, development updates, community engagement, and competitive positioning.

Step 2: Secure Trading Infrastructure

Choose reputable exchanges with strong security, broad asset coverage, reasonable fees, and good support. Enable two-factor authentication and store assets securely in wallets.

Step 3: Risk Management Framework

Define total investment amount, set position sizes, establish stop-loss and take-profit levels, and decide on leverage use beforehand.

Step 4: Position Sizing and Phased Entry

Avoid deploying all capital at once. Use dollar-cost averaging across multiple phases to reduce entry price risk and psychological stress.

Conclusion: How to Approach Altcoin Season

Altcoin season offers the most exciting and potentially profitable opportunities in the crypto market cycle. However, it also involves significant risks.

The upcoming altcoin season, supported by stablecoin liquidity and institutional participation, is a more structural and sustainable movement than past speculative surges. Opportunities span multiple sectors—from AI to Metaverse—providing investors with unprecedented choices.

Success depends on diligent information gathering, disciplined risk management, and a deep understanding of market cycles. Avoid chasing hype; instead, adopt a systematic, disciplined approach. Consistently lock in profits, limit losses, and stay alert to regulatory and sentiment shifts. These are the hallmarks of investors who can truly benefit from altcoin season.

The cryptocurrency market remains in evolution, with market cycle patterns continuously changing over time. Understanding the essence of altcoin season, learning from history, and making informed decisions tailored to the current environment are keys to thriving in this dynamic era.
