For years, crypto investors have relied on a simple model: the 4-year cycle. Every four years, a Bitcoin halving kicks off a predictable series of events—Bitcoin rallies, Ethereum follows, altcoins explode, and eventually, a crash resets the cycle.

But this time? The game may have changed.

In this article, we explore why the 2024-2025 crypto cycle could be different—and what that means for your portfolio.

History Doesn’t Repeat, But It Rhymes

Historically, the 4-year cycle has shaped the crypto market:

Bitcoin halving creates a supply shock, drastically reducing the number of new BTC entering circulation. This historically causes a supply-demand imbalance that pushes prices higher.
BTC leads the market, often being the first to break out before capital rotates into Ethereum and then altcoins.
Prices peak in euphoria, driven by media hype, speculative mania, and irrational exuberance.
A multi-year bear market follows, characterized by low volumes, price drops, and fading interest, before the cycle resets again.

This pattern defined 2013, 2017, and 2021—but 2024 is already deviating.

Boom and Bust: Previous Cycle Peaks

Each previous bull run ended with a major correction:

2013: BTC surged to $1,100, then dropped to $200—a brutal -82% crash.
2017: BTC reached $20,000, only to fall to $3,000, shedding 85% of its value.
2021: BTC climbed to $69,000 before plunging to $16,000, a 77% correction.

These busts wiped out unsustainable gains and signaled the start of each bear cycle. In 2024, Bitcoin broke through to $109,000—but this time, Ethereum and altcoins aren’t following the same path.

Bitcoin and Ethereum: The Decoupling Begins

Ethereum has traditionally mirrored Bitcoin’s movements:

In 2017, Bitcoin’s $20K high was followed by ETH reaching $1,400.
In 2021, BTC’s $69K peak aligned with ETH surging to $4,800.
In 2025, despite BTC touching $109K, ETH remains significantly below its previous all-time high.

This disconnect suggests a potential structural change in market dynamics. Investors are questioning whether ETH—and the broader altcoin market—can still rely on BTC’s momentum.

Key Factors Making 2024-2025 Unique

Institutional Adoption and ETFs

This is the first cycle where institutional investors are fully participating through regulated financial instruments. Spot Bitcoin ETFs have opened the floodgates for traditional finance to enter crypto legally and safely. Over 250,000 BTC are already held by ETFs, reflecting strong institutional conviction. In fact, ETF inflows now exceed daily mining supply, creating consistent upward pressure on price.

This influx of “smart money” is changing the tone of the market. It’s no longer just retail traders speculating—it’s long-term capital deploying billions.

Governments: From Bans to Strategic Reserves

Governments have historically tried to ban or restrict crypto, fearing loss of control. But now, the stance is changing. In 2025, the U.S. formed a Strategic Bitcoin Reserve, signaling a shift in perspective. Countries like UAE, Singapore, and Hong Kong are implementing crypto-friendly regulations and attracting crypto businesses.

This regulatory shift reduces uncertainty, builds trust, and signals that crypto may become part of official financial frameworks.

Retail FOMO Is Missing—For Now

Retail mania has been a hallmark of previous bull markets. In 2017, it was driven by ICOs promising life-changing returns. In 2021, DeFi and NFTs exploded onto the scene, capturing mainstream attention. But in 2024, despite booming interest in AI, retail enthusiasm for crypto remains lukewarm.

Many retail investors are still watching from the sidelines, waiting for a clear and relatable crypto use case. Without them, we haven’t seen the explosive growth typical of previous altseasons.

Unseen Shocks: Black Swans That Shaped This Cycle

No crypto cycle is without its share of unexpected disasters. This one is no different. The FTX collapse in 2022 wiped out over $10 billion, shook user confidence, and exposed flaws in centralized platforms. Then came the Mt. Gox repayments in 2024, bringing thousands of dormant BTC back into circulation, potentially adding volatility.

Despite these black swan events, Bitcoin managed to reach a new all-time high—a testament to the market’s growing resilience.

Where’s the Altseason?

Historically, after Bitcoin’s rally, profits rotate into Ethereum and altcoins. But so far, that flow has stalled. Bitcoin dominance has stayed above 50%, suggesting capital is remaining concentrated in BTC. Ethereum is underperforming, failing to follow BTC to new highs. There’s no strong retail narrative to bring fresh attention to altcoins, unlike the compelling stories of ICOs or NFTs in past cycles.

Without capital rotation and retail hype, altcoin performance has remained subdued.

Are Altcoins Dead?

Some analysts argue that altcoins have lost their edge in this cycle. There are no major breakout sectors like DeFi or NFTs that have captured widespread attention. The ETH/BTC ratio is falling, a technical sign that Ethereum and altcoins are weakening relative to Bitcoin.

Additionally, the current AI trend doesn’t rely on blockchain, which limits the narrative crossover potential. While not dead, altcoins may be entering a phase of stagnation or reevaluation.

Why Altcoins Fail (and What It Means for 2024)

Altcoins often follow a pattern: a flashy narrative, early hype, and then a long decline. But why do so many fail—even during bull markets?

One of the biggest reasons is poor tokenomics. Many tokens lack a real use case or have inflationary supply structures that dilute value. Even worse, insiders often hold a majority of the tokens, creating sell pressure during unlock periods.

Narrative fatigue is another factor. Hype cycles can only last so long. If a project doesn’t continue to innovate or attract real users, interest fades quickly. Projects with no product-market fit—those that solve no real-world problem—fail to sustain any long-term value.

VC funding can also be a double-edged sword. While it brings early capital, it often leads to large token unlocks that suppress prices. This can crush community confidence, especially if the project hasn’t proven its utility by the time tokens start unlocking.

In 2024, these weaknesses are being exposed more than ever. With retail investors cautious and institutions focused on Bitcoin, weak altcoins are being left behind. This doesn’t mean all alts are doomed—but it does mean survival now depends on real value, not just hype.

Or Is One Last Altseason Yet to Come?

There’s still a possibility for altcoins to shine—if conditions align. If Bitcoin stabilizes and consolidates, traders often look to altcoins for better risk-reward opportunities. Ecosystems like Arbitrum and Optimism are showing signs of real utility and growth.

Tokenized real-world assets (RWAs) are gaining momentum, offering a tangible bridge between blockchain and traditional finance. If retail FOMO returns, perhaps triggered by a new narrative or breakout use case, altcoins could still rally hard before the cycle ends.

The ingredients are there—it’s just a matter of timing and sentiment.

Final Verdict: A Crypto Cycle Unlike Any Other

This cycle is defying expectations and rewriting the playbook:

Institutional investors are leading the charge, changing the pace and nature of the market.
Spot ETFs are creating daily buy pressure, fundamentally altering Bitcoin’s supply-demand dynamics.
Government support is rising, bringing legitimacy and reducing long-term risk.
Altcoins lag behind, with no clear narratives or retail mania driving growth.

Whether you’re a Bitcoin maximalist or altcoin investor, one thing is clear—this crypto cycle is unlike any we’ve seen before. The next few months will determine whether this is a cycle of consolidation or a late-stage altcoin explosion.

DYOR always. This article is for informational purposes only and not financial advice.
