Altseason 2024-2026: Opportunities and Challenges as Altcoins Shine

The cryptocurrency market never stands still. It goes through continuous cycles of volatility, and within those, altseason — the period when altcoins outperform Bitcoin in price gains — always attracts investor attention. Not just a random phenomenon, altseason is an essential part of the market cycle, offering huge profit opportunities but also hiding significant risks. As of February 2026, with Bitcoin maintaining a price of $67,990 and a market share of 55.56%, the market shows potential signs of altseason turbulence. To seize these opportunities wisely, investors need to understand the nature of altseason, its historical phases, and appropriate risk management strategies.

What Is Altseason? Understanding the Season of Altcoins

Altseason refers to a period when the total market capitalization of all altcoins (cryptocurrencies outside Bitcoin) surpasses Bitcoin during a bullish run in the crypto market. This isn’t a sudden event but results from shifts in investor psychology and financial flows.

During altseason, the price increases and trading volume of altcoins attract significant attention from the global investment community. This occurs when confidence in the crypto market extends beyond Bitcoin, creating a ripple effect that encourages capital to flow into emerging cryptocurrencies. This trend usually begins when Bitcoin’s price has risen to a high level, making individual investors feel the entry cost is too high, prompting them to shift focus to lower-priced altcoins with higher profit potential.

Altseason represents a revolutionary phase in the crypto market. It’s when Bitcoin’s market dominance — a measure of Bitcoin’s market cap relative to the total market cap — drops significantly, often below 50%. This decline signals that investors are turning their attention to alternatives, paving the way for altseason to develop.

Altseason Cycles vs. Bitcoin Dominance: Two Sides of the Market

The crypto market oscillates between two main states: altseason and Bitcoin dominance. Each phase has distinct characteristics, and understanding the difference is key to making sound investment decisions.

In altseason, resources are concentrated in altcoins. The market shifts focus from Bitcoin to thousands of other cryptocurrencies. The value and trading volume of altcoins surge, often driven by factors such as speculative trading, new project launches, technological advancements, and practical applications. During this period, Bitcoin remains stagnant or even slightly declines in relative gains.

Conversely, Bitcoin season is when investor confidence is heavily centered on Bitcoin. During this time, Bitcoin’s dominance index rises, sometimes exceeding 60%. In these periods, altcoins are often neglected, with prices stagnating or even decreasing. This shift can be caused by perceptions of Bitcoin’s stability, its status as “digital gold,” or investors seeking safety amid market instability.

In a bear market, investors tend to revert to Bitcoin or stablecoins as safer, lower-risk options. Capital flows from altcoins back into Bitcoin, sparking a new Bitcoin season.

From ICOs to DeFi, NFTs, and AI: The History of Altseason Volatility

The history of altseason isn’t a straight line. It’s a series of waves — each carrying different trends, technologies, and market psychology.

Late 2017 - Early 2018: The ICO Bubble

This was the most “primitive” altseason. Bitcoin’s dominance peaked at 87% before plunging to 32% in January 2018. The total crypto market cap skyrocketed from around $30 billion to over $600 billion within a year.

The cause was the ICO (Initial Coin Offering) frenzy. Thousands of new projects launched, promising revolutionary technology and applications. Investors rushed to buy new tokens, driven by the desire for quick wealth. Many altcoins reached all-time highs (ATH). However, this bubble burst in 2018 when most ICO projects proved to be elaborate scams.

Early 2021: DeFi, NFTs, and Meme Coins Explode

2021 saw a much larger altseason. Bitcoin’s dominance dropped from 70% to 38%, while altcoin market share increased from 30% to 62%. The total market cap surpassed $2 trillion for the first time, later exceeding $3 trillion by year-end.

Unlike the ICO bubble, the 2021 altseason was driven by three main trends:

DeFi (Decentralized Finance): Lending protocols, decentralized exchanges like Uniswap, Curve, and lending platforms like Aave created a new financial ecosystem. Investors capitalized on yield farming and liquidity mining.

NFTs: Non-fungible tokens gained fame with multi-million-dollar auctions. The story of Beeple, whose NFT sold for $69 million, drew global attention.

Memecoins: Dogecoin and Shiba Inu suddenly surged, initially created for fun but attracting millions of investors, many of whom made enormous profits.

Notable projects during this phase included Solana, Polygon, BNB, PancakeSwap — projects that delivered real value to investors.

Q4 2023 - Q1 2024 and New Signals

By late 2023 and early 2024, altseason entered a new phase. This time, optimism was fueled by two key events:

Bitcoin Halving (April 2024): This event reduces Bitcoin’s mining rewards. Historically, it has led to significant price rallies within 6-12 months afterward.

Ethereum ETF (May 2024): SEC approval of spot Ethereum ETFs opens opportunities for institutional investors to participate in the crypto market.

Unlike previous altseasons, the 2024-2026 phase features notable diversification across sectors. Instead of focusing solely on ICOs, DeFi, or NFTs, this altseason sees “waves” across various fields:

• AI & Machine Learning: Projects like Fetch.ai focus on decentralized artificial intelligence.
• DePIN (Decentralized Physical Infrastructure): Building decentralized physical infrastructure.
• GameFi & Metaverse: Continuing from 2021, with more practical applications.
• Web3: Projects like Arweave (data storage), Worldcoin (digital identity), and new memecoins like dogwifhat create unexpected opportunities for investors.

How to Recognize the Beginning of Altseason? Key Signals

While there’s no foolproof way to predict altseason, certain indicators can help investors identify its onset.

Bitcoin dominance below 50%: This is the clearest sign. When this index drops below 50%, it indicates Bitcoin no longer holds its previous dominance.

Rising altcoin trading volume: A significant increase in altcoin trading volume suggests investors are shifting focus.

Overall market optimism: When positive sentiment spreads across the entire crypto market — not just Bitcoin — it signals that altseason may be starting.

Specific events: Launches of promising altcoin projects or regulatory developments supporting altcoins can trigger altseason.

As of February 2026, with Bitcoin’s market share at 55.56% and emerging sectors like DePIN, AI, and others gaining traction, investors should watch for signs that altseason is gathering momentum.

Trading Strategies During Altseason: From Selection to Risk Management

When altseason begins, profit opportunities can be enormous, but so are the risks. A solid trading strategy is essential.

Thorough Research: Before investing in any altcoin, conduct deep research. Understand fundamentals: development team, underlying technology, real-world use cases, and market potential. Avoid being swept up in hype without understanding what you’re investing in.

Diversify Your Portfolio: The principle “Don’t put all your eggs in one basket” remains true. Spread investments across multiple promising altcoins to reduce risk. A prudent approach is to allocate 60% to large-cap altcoins, 30% to mid-cap, and 10% to small, high-risk, high-reward projects.

Strict Risk Management: Always set stop-loss orders to protect capital if the market turns. Maintain a reasonable risk-to-reward ratio, such as 1:3 or 1:5 — meaning potential profit should be 3-5 times the maximum loss.

Partial Profit Taking: When your altcoin doubles or triples in value, consider selling part of your holdings to lock in profits. This strategy helps protect your initial capital while still allowing for potential gains.

Realistic Expectations: While altseason can bring high returns, not all altcoins will increase in value. Historically, about 80% of altcoins in a cycle won’t meet your profit targets. Setting realistic expectations helps avoid impulsive decisions.

Hidden Risks in Altseason You Can’t Ignore

Altseason is an opportunity but also fraught with danger. These risks must always be considered:

Extreme Volatility: Altcoin prices often fluctuate 2-3 times more than Bitcoin. A coin might surge 50% in a day and drop 40% the next. Your trading setup must be prepared for rapid swings.

Price Bubbles and Sudden Crashes: Overhyped assets can burst spectacularly. History in 2018 and 2022 shows how quickly markets can collapse.

Rug Pulls and Scams: Some altcoin projects are outright scams. Developers may raise funds and then disappear or sell off their tokens (“rug pull”), causing prices to plummet to zero. Be cautious of projects with unclear backgrounds.

Pump-and-Dump Schemes: Groups may artificially inflate an altcoin’s price and then sell off, causing sharp declines.

Regulatory Risks: Changes in government policies or regulations can have a major impact. For example, SEC’s declaration of Ethereum as a security in 2018-2019 negatively affected many altcoins. Conversely, positive approvals like Bitcoin or Ethereum ETFs can stimulate altseason. Staying informed on global regulatory developments is crucial.

Conclusion

Altseason isn’t a random event but a cyclical phase of the crypto market. From the ICO craze of 2017-2018 to the DeFi and NFT boom in 2021, and the rise of AI and DePIN in 2024-2026, each altseason offers lessons, opportunities, and pitfalls.

To succeed during altseason, investors need three things: deep understanding, discipline, and robust risk management. Stay updated, diversify your portfolio, develop clear strategies, and most importantly — never invest more than you can afford to lose. Altseason can bring substantial profits, but only for those who are well-prepared.
