Inside the 2025 altcoin divergence: Could 2026 be an ‘L1 season’?

ambcryptoPublished on 2026-01-01Last updated on 2026-01-01

Abstract

In 2025, the crypto market witnessed a notable divergence: altcoins, including Ethereum (ETH), underperformed Bitcoin (BTC) in price, with ETH closing the year down nearly 11%. However, this price weakness contrasted with robust on-chain fundamentals. Ethereum processed a record 2.23 million transactions with low fees and no congestion, a trend mirrored by other Layer 1 (L1) networks. This disconnect between speculation and utility is drawing significant attention. As 2026 begins, the focus is shifting from speculative hype to real network activity, driven by factors like the RWA market and stablecoins. With strong on-chain metrics and growing institutional ETF flows, the foundation is set for a potential "L1 season" where utility takes center stage.

2026 has started with renewed momentum in the altcoin market.

The Altcoin Season Index is ticking higher, signaling a rotation back into alts. That said, when looking back at the 2025 cycle, a clear divergence stood out, with investors deviating from the usual rotation playbook.

Historically, altcoins tended to outperform during periods of Bitcoin [BTC] consolidation. This cycle, that rotation never fully played out.

The ETH/BTC ratio stayed range-bound, capping Ethereum’s [ETH] speculative upside.

Notably, that dynamic showed up clearly in 2025 returns.

From a technical lens, ETH closed the year down 10.97%, entering the new year below the $3k level. Bitcoin, by contrast, held up better, finishing 2025 down 6.24%, suggesting capital largely stayed parked in BTC.

Still, despite the weakness, Ethereum continued to post strength across key on-chain metrics.

In fact, this wasn’t isolated to Ethereum. Similar upticks were seen across other L1s, highlighting a clear divergence this cycle.

Naturally, the disconnect between price action and fundamentals is drawing attention. With the “speculative” narrative for altcoins under scrutiny, all eyes are now on L1s. Is 2026 shaping up to be their season?

2026 altcoin divergence: Speculation vs. utility

As the new year kicks off, predictions are heating up.

Notably, one theme stands out: Layer 1 utility. From the RWA market and stablecoins to chain-specific upgrades, 2026 is starting to show a clear focus on real network activity rather than just speculative “hype.”

The key part? On-chain numbers back this up.

As the chart below highlights, Ethereum recently processed a record 2.23 million transactions, the largest in its 10-year history, while keeping fees under $0.01 and finality stable, showing no network congestion.

What’s more, other Layer 1s are showing the same trend.

In this context, AMBCrypto’s thesis starts to gain weight. While 2025 didn’t deliver an “altcoin season,” the market still saw a clear shift, with growing ETF flows toward these altcoins showing the trend is more than a one-off.

Now, as the market heads into 2026, the foundation stands strong.

High-cap altcoins are showing solid on-chain usage, while speculative activity is beginning to fade, creating a divergence that could spark a full-blown “L1 season,” with Layer 1 networks finally taking the spotlight.


Final Thoughts

  • Despite altcoins underperforming Bitcoin in 2025, on-chain activity shows strong fundamentals, signaling a divergence between speculation and usage.
  • With high-cap altcoins showing solid network activity, 2026 could be defined by a full-blown Layer 1 season.

QHow did Ethereum's (ETH) price performance in 2025 compare to Bitcoin's (BTC)?

AEthereum closed the year 2025 down 10.97%, falling below the $3,000 level. In contrast, Bitcoin held up better, finishing the year down only 6.24%.

QWhat on-chain metric for Ethereum reached a record high, demonstrating strong fundamental activity?

AEthereum recently processed a record 2.23 million transactions, the largest number in its 10-year history, while maintaining low fees under $0.01 and stable network finality without congestion.

QAccording to the article, what is the main theme that is starting to define the altcoin market in 2026?

AThe main theme defining the 2026 altcoin market is a focus on Layer 1 utility, including real-world asset (RWA) markets, stablecoins, and chain-specific upgrades, rather than just speculative hype.

QWhat does the article suggest could be the result of the current divergence between price action and fundamentals?

AThe article suggests that the divergence between weak price performance and strong on-chain fundamentals could spark a full-blown 'L1 season' in 2026, where Layer 1 networks take the spotlight.

As Consensus Accelerates, What Are Young Investors Betting On?

Title: As Consensus Forms Faster, What Are Young Investors Betting On? In the rapid evolution of tech investment, a new generation of young investors is navigating a landscape where AI, robotics, commercial aerospace, and quantum computing are advancing simultaneously. Traditional investment logic based on financial models is giving way to a need for deep technical understanding and the ability to act before industry consensus forms. An analysis of trends from the "WAIC FUTURE TECH" list of young investment leaders reveals key shifts in focus. The first major trend is the movement of AI from the digital screen into the physical world. Investment is shifting from large language models and chatbots towards embodied AI, robotics, AI hardware, and edge computing. While demonstrations generate excitement, the real challenge lies in achieving scalable, reliable, and cost-effective delivery in complex real-world environments like factories and logistics. Success depends not just on algorithms but on the integration of sensors, actuators, and control systems. Second, the competitive focus for large models is moving beyond raw capability toward building an "intelligence flywheel." The goal is to create self-reinforcing systems where user interaction generates data, improving the model, which in turn enhances the user experience and attracts more engagement. Companies that successfully embed AI into workflows to create these closed-loop systems can build lasting value that isn't easily erased by the next model upgrade. Third, facing a potential bottleneck in high-quality human-generated data, investors are looking at new underlying technologies. Reinforcement learning and self-play, as demonstrated by AlphaGo Zero, offer paths for AI to generate its own experience. Scientific foundation models, which aim to build general AI capabilities for fields like life sciences and materials discovery, represent a non-consensus direction that could unlock new frontiers of knowledge and data. Finally, in deep-tech areas like quantum computing, commercial aerospace, and space-based infrastructure, patient capital is essential. These fields have long, uncertain development and validation cycles involving complex engineering, supply chains, and regulations. Investment here requires a long-term view, focusing on foundational team capabilities and the eventual emergence of market demand, even if commercial returns are distant. Collectively, these trends illustrate how young investors are adapting to a new era. They are learning to make earlier, technically-informed judgments, balance hype with real-world viability, and provide the patient capital needed to build the deep-tech foundations of the future.

Can Japan Buy Growth with AI? Will the Bond Market Believe It?

Japan's cabinet has introduced the 2026 Basic Policy on Economic and Fiscal Management and Reform, shifting its primary fiscal target. The new framework moves away from the traditional annual primary balance goal and instead prioritizes a stable reduction of the debt-to-GDP ratio. This change is tied to a strategy of increased "responsible proactive fiscal" spending, aiming to boost long-term growth through investments in strategic sectors like AI, semiconductors, energy, and robotics. The government estimates total public and private investment in 62 key technologies could exceed 370 trillion yen by 2040. The market reaction has been mixed and cautious. While equity markets may respond to policy signals, bond markets are focused on fiscal credibility. Concerns center on whether the weakening of the clear primary balance anchor could lead to looser fiscal discipline. If investors doubt that these strategic investments will generate sufficient productivity gains, tax revenue, and nominal growth to outpace rising interest costs, they may demand higher yields on Japanese Government Bonds (JGBs). Recent volatility in the yen and JGB yields, with the 10-year yield briefly reaching 2.9%, reflects this skepticism. The success of this new framework hinges on two factors: whether Japan can achieve a nominal growth rate consistently higher than its long-term interest rates, and whether future budgets demonstrate disciplined control over bond issuance. The government's narrative is that strategic investment is essential to break Japan's cycle of low growth, aging, and labor shortages. However, the bond market will continuously assess the credibility of this plan, pricing the risk that it may represent fiscal expansion rather than a viable growth strategy.

Misjudged A-Shares: Resilience, Expectations, and Confidence

China's A-share market recently faced selling pressure, especially in tech sectors, initially triggered by a global tech sell-off that began in South Korea. However, the article argues this is a case of "mistaken injury" and highlights the market's underlying resilience. This resilience stems from three main pillars: **1) Tech Sector Fundamentals:** Unlike Korea's market dominated by a few memory chip stocks, China's tech sector is diversified across computing, communications, electronics, and semiconductors, supported by dual narratives of global AI supply chains and domestic substitution. Core areas like optical modules and fiber optics continue to show strong earnings growth. **2) "National Team" Support:** State-backed institutions and large corporations have made significant market purchases and announced buybacks, providing liquidity and signaling confidence. This is seen as a stabilizing policy signal, often associated with market bottoms. **3) Broader Market Pillars:** Other major sectors are showing endogenous recovery momentum. Consumer stocks benefit from stabilizing CPI and signs of sector recovery (e.g., liquor price hikes). Cyclical sectors like aluminum have high earnings, potential price increases due to tight supply, and low valuations. The financial sector offers stable dividends and low valuations. The conclusion is that the sell-off was driven by external contagion, not a collapse in fundamentals. With strong policy support and recovering momentum across key sectors, the A-share market possesses the toughness to regain stability.
