The cryptocurrency market has faced significant turbulence over the past week. While short-term price movements remain unpredictable, a closer look at historical patterns reveals striking similarities between today’s market dynamics and those seen during Bitcoin’s peak in late 2017. Two key indicators from that period have re-emerged—raising an important question: Has the current bull market already run its course?
Understanding these parallels isn’t just about nostalgia—it offers valuable insights into market psychology, institutional adoption cycles, and the typical progression of crypto bull runs. By analyzing past behavior, investors can make more informed decisions about what might come next.
Bitcoin Peaks at Institutional Milestones
One of the most telling signs that a crypto bull cycle may be nearing its end is when Bitcoin reaches its all-time high (ATH) coinciding with a major institutional milestone.
In April 2025, Bitcoin surged to just under $65,000—its highest price at that time—on April 14, the very day Coinbase went public via a direct listing on Nasdaq. This event marked a watershed moment for the industry: a leading cryptocurrency exchange achieving mainstream financial legitimacy.

This pattern is not new.
Back in December 2017, Bitcoin hit its then-record high of nearly $20,000 on December 17—the same day the Chicago Mercantile Exchange (CME) launched Bitcoin futures contracts. This move brought regulated derivatives into the mainstream financial system, signaling growing institutional interest and acceptance.
The recurrence of this pattern suggests a consistent trend: Bitcoin often peaks when crypto transitions from fringe speculation to institutional recognition. These milestones act as catalysts for final price surges, driven by media hype and late-stage investor FOMO (fear of missing out).
The Leadership Shift: Bitcoin Leads, Altcoins Follow
Another hallmark of mature bull markets is the sequential performance shift between Bitcoin and alternative cryptocurrencies (altcoins).
Historically, Bitcoin tends to peak first, followed by a delayed rally in altcoins like Ethereum, Solana, or Ripple. This sequence reflects how capital flows through the market:
- Early adopters buy Bitcoin—the most liquid and trusted asset.
- As confidence grows, investors rotate into riskier but potentially higher-return altcoins.
- When even speculative coins surge, it signals market euphoria—and often, the end of the cycle.
2017 Pattern: Bitcoin Tops Before Altcoins
In the 2017 cycle:
- Bitcoin peaked on December 17, 2017
- Ripple (XRP) reached its all-time high nearly two weeks later, in early January 2018
- Many smaller altcoins continued climbing into Q1 2018
This lag indicates that retail momentum was strongest after Bitcoin’s rise had already stalled—classic late-stage behavior.
2025 Repeat: History Rhymes Again
Fast forward to 2025:
- Bitcoin reached its peak around mid-March
- Ethereum and several major altcoins hit their highs weeks later, in late April
- Smaller-cap tokens saw explosive gains even after Bitcoin began correcting
This delayed altcoin surge mirrors the 2017 playbook almost exactly. It suggests that while Bitcoin may have already completed its upward leg, speculative energy temporarily shifted to lesser-known projects—often a sign of market exhaustion.
Why These Patterns Matter
These two recurring signals—institutional milestone timing and Bitcoin-to-altcoin leadership rotation—are more than coincidences. They reflect deeper market mechanics:
- Institutional validation acts as a psychological ceiling: Once big players enter via regulated products (like futures or IPOs), early adopters often cash out.
- Retail investors chase momentum last: By the time mainstream news covers crypto gains and friends start asking about “the next Dogecoin,” the smart money is already exiting.
- Market cycles follow adoption curves: From innovators to early adopters, then the masses—the final phase typically ends with widespread enthusiasm and collapsing inflows.
When both signals align—as they did in late 2017 and again in early 2025—it increases the likelihood that the bull market has reached its climax.

Are We at the End of the Bull Run?
It's impossible to call exact market tops with certainty. However, the reappearance of these two key patterns suggests caution is warranted.
That doesn’t mean prices will crash overnight. Post-peak markets can remain volatile for months, with rallies and corrections alternating before a clear downtrend emerges. But it does mean:
- The highest probability of outsized returns has likely passed
- Risk management should take priority over aggressive speculation
- Diversification into stable assets or dollar-cost averaging out may be prudent
Moreover, macroeconomic factors in 2025—such as interest rate policy, inflation trends, and global liquidity—also play critical roles in sustaining or ending bull markets.
Frequently Asked Questions (FAQ)
Q: Does a Bitcoin peak during an institutional event always signal a bear market?
A: Not always—but it’s a strong warning sign. Events like Coinbase’s IPO or CME futures launches bring massive attention and liquidity. Once the hype fades and early investors take profits, downward pressure often follows.
Q: Can altcoins keep rising even if Bitcoin peaks?
A: Yes, temporarily. In both 2017 and 2025, many altcoins rallied after Bitcoin topped out. However, these rallies are usually short-lived without sustained Bitcoin strength to support broader market sentiment.
Q: How long after Bitcoin peaks do bear markets begin?
A: There's no fixed timeline. In 2017, significant declines started within weeks; in previous cycles, consolidation lasted months. On-chain metrics like exchange inflows, whale movements, and funding rates help gauge timing.
Q: Is it too late to invest in crypto now?
A: "Too late" depends on your strategy. Long-term holders may still benefit from future cycles. However, entering at peak sentiment carries higher risk. Consider dollar-cost averaging and portfolio allocation limits.
Q: What comes after a bull market ends?
A: Typically, a correction (20–40% drop), followed by a prolonged consolidation or "crypto winter." During this phase, weaker projects fail, infrastructure improves, and institutional players accumulate—setting the stage for the next cycle.
Final Thoughts: What Comes Next?
History doesn’t repeat—but it often rhymes.
The convergence of institutional milestones and Bitcoin leading altcoins to their peaks has happened before—and each time, it marked the beginning of a major market shift. While we can't predict exact price levels or dates, recognizing these patterns helps investors stay ahead of sentiment swings.
Rather than trying to time the absolute top or bottom, focus on building resilient strategies:
- Use volatility as an opportunity, not a threat
- Monitor on-chain data and funding rates
- Stay diversified across asset classes
And remember: every bear market eventually sets up the next bull run.
