Altcoin Season Index Plummets to 18: Is Altcoin Season Over?

The cryptocurrency market just received a sobering signal. CoinMarketCap’s Altcoin Season Index has fallen to 18, dropping another point and moving further away from the critical threshold that defines an altcoin season. For investors watching market cycles, this number tells a compelling story about where capital is flowing right now. Let’s decode what this shift means for your portfolio.

What is the Altcoin Season Index Telling Us?

The Altcoin Season Index serves as the market’s pulse check. It currently sits at a mere 18, a clear indicator that Bitcoin is commanding the stage. This index is calculated by comparing the 90-day performance of the top 100 cryptocurrencies (excluding stablecoins) against Bitcoin itself. A reading above 75 signals an altcoin season, where most altcoins outperform Bitcoin. Therefore, a score of 18 is a stark contrast, highlighting strong Bitcoin dominance.

Why is Bitcoin Dominating the Market?

Several factors are converging to fuel Bitcoin’s strength while the Altcoin Season Index languishes. First, macroeconomic uncertainty often drives investors toward perceived safe-haven assets within crypto, with Bitcoin being the primary beneficiary. Second, major institutional products like Spot Bitcoin ETFs are funneling significant capital directly into Bitcoin, not the broader altcoin market. Finally, the market cycle theory suggests periods of Bitcoin leadership typically precede altcoin rallies, making this a phase of accumulation and patience for altcoin investors.

Key Implications for Crypto Investors

Understanding the Altcoin Season Index is crucial for making informed decisions. Here are the immediate takeaways:

  • Risk Appetite is Low: A low index suggests a risk-off environment where capital retreats to the largest, most established asset.
  • Timing Your Entry: For altcoin buyers, this period can be an opportunity to research and identify strong projects at relatively lower prices before a potential season shift.
  • Portfolio Rebalancing: It may be a prudent time to review your allocation between Bitcoin and altcoins based on your risk tolerance.

Historically, the index doesn’t stay at extreme lows forever. However, predicting the exact turn is challenging. The current trend emphasizes that we are firmly in a Bitcoin season.

When Could the Altcoin Season Return?

While the Altcoin Season Index is low, it’s not a permanent state. Market cycles rotate. A return to altcoin season typically requires a sustained period of Bitcoin stability or consolidation, allowing investor confidence and capital to trickle down into smaller-cap projects. Key triggers to watch include:

  • Bitcoin establishing a strong, steady price floor.
  • Increased development activity and positive news flow from major altcoin ecosystems.
  • A general improvement in global liquidity and risk sentiment.

Monitoring the Altcoin Season Index weekly can provide an early, data-driven hint of this sentiment change.

Conclusion: Navigating the Current Crypto Winter for Altcoins

The Altcoin Season Index at 18 is a clear, quantitative message: patience is essential. Bitcoin is in the driver’s seat. For the savvy investor, this isn’t a time for fear, but for strategic preparation. Use this phase to conduct thorough research, build watchlists, and plan your strategy for when the market dynamics eventually shift. Remember, the most successful investors understand cycles, not just prices.

Frequently Asked Questions (FAQs)

What does an Altcoin Season Index of 18 mean?
An index value of 18 means only a small percentage (far less than 75%) of the top altcoins have outperformed Bitcoin over the last 90 days, indicating strong Bitcoin dominance and a ‘Bitcoin season’.

How often is the Altcoin Season Index updated?
The index is typically updated daily, providing a near real-time gauge of market performance trends between Bitcoin and altcoins.

Should I sell my altcoins when the index is this low?
Not necessarily. A low index indicates a market phase, not a verdict on every project. It’s a signal to reassess your portfolio’s risk and potentially rebalance, but panic selling is rarely a good strategy.

Can the index predict future prices?
No, it is a lagging indicator based on past 90-day performance. It describes the current market structure but does not forecast future price movements of individual assets.

What is a good Altcoin Season Index score for buying altcoins?
There’s no perfect score. However, a rising trend above 50 can signal increasing altcoin strength. Some investors use a crossing above 75 as a confirmation signal for altcoin season.

Where can I check the Altcoin Season Index?
The index is publicly available on CoinMarketCap’s website under their market data or research sections.

“I Wasted 8 Years in Crypto”: A Builder’s Exit Note Goes Viral Across Asia

The post “I Wasted 8 Years in Crypto”: A Builder’s Exit Note Goes Viral Across Asia appeared on BitcoinEthereumNews.com. “I am NOT building a new financial system. I built a casino.”This stark admission from Ken Chan, former co-founder of derivatives protocol Aevo, has been reverberating across Asian crypto communities this week. What began as a post on X has now crossed linguistic borders, been introduced to Chinese communities by local news media, and been widely shared among Korean traders, accumulating millions of views along the way. Sponsored Sponsored From Ayn Rand to Disillusionment: A Libertarian’s Journey Through Crypto Chan’s confession is not merely a critique—it is the unraveling of a personal ideology. He describes himself as a “starry-eyed libertarian” who donated to Gary Johnson’s 2016 presidential campaign after being radicalized by Ayn Rand’s novels. The cypherpunk ethos of Bitcoin spoke directly to this worldview. “Being able to walk across the border with a billion dollars in your head is and always will be a powerful idea to me,” he writes. Yet eight years of industry experience eroded that idealism. Chan recounts how the Layer 1 wars—the flood of capital into Aptos, Sui, Sei, ICP, and countless others—produced no meaningful progress toward a new financial system. Instead, it “literally torched everyone’s money” in pursuit of becoming the next Solana. His verdict is unsparing: “We do not need to build the Casino on Mars.” According to his LinkedIn profile, Chan departed Aevo in May this year. His personal website indicates he is now working on KENSAT, a personal satellite project. It is scheduled to launch aboard a Falcon 9 in June 2026. His confession arrives six months after his departure. It comes as AEVO token trades at roughly $45 million in fully diluted market cap—down approximately 99% from its peak. Chan’s central metaphor—that crypto has become “the biggest, online, multi-player 24/7 casino our generation has ever concocted”—cuts through technical complexity with…

Bitcoin faces quantum risk: Solana co-founder issues warning

Bitcoin faces quantum risk: Solana co-founder issues warning

The post Bitcoin faces quantum risk: Solana co-founder issues warning appeared on BitcoinEthereumNews.com. Solana co-founder Anatoly Yakovenko has warned that Bitcoin developers must prepare for a potential quantum computing breakthrough that could render the network’s current security measures outdated. Summary At the All-In Summit, Solana co-founder Anatoly Yakovenko reignited debate over Bitcoin’s long-term security. There’s a “50/50” chance that quantum computers could break its cryptographic defenses within five years. Rapid advances in AI show how quickly theory can become reality. The question is not just if Bitcoin must migrate to quantum-safe cryptography—but when. According to Yakovenko, who was speaking at the All-In Summit 2025, there is a “50/50” probability that within five years, quantum computers will be strong enough to crack the cryptographic safeguards protecting Bitcoin wallets. The concern centers on quantum machines running algorithms like Shor’s, which could crack the Elliptic Curve Digital Signature Algorithm currently protecting Bitcoin (BTC) private keys. This would allow attackers to forge transactions and compromise wallets, creating an existential risk for the network. Yakovenko argued that “we should migrate Bitcoin to a quantum-resistant signature scheme” before such technology becomes viable. Skeptics like Blockstream’s Adam Back downplay immediacy of threat The Bitcoin community remains divided on the urgency of quantum threats. Adam Back, CEO of Blockstream, estimated that the technology is still relatively far away and argued that making Bitcoin quantum-ready is “relatively simple.” Bitcoin Core contributor Peter Todd dismissed current quantum computers as non-existent, stating that “demos running toy problems do not count.” Luke Dashjr, another Bitcoin Core contributor, suggested quantum threats pose less immediate danger than spam transactions and developer corruption issues the community currently faces. Bitcoin’s design complicates any quantum upgrade. A migration to post-quantum cryptography would require a hard fork, a highly contentious and technically complex process needing widespread network support. Yakovenko countered skepticism by pointing to quick AI advances as evidence of how…
