In July 2018, after a grueling seven-month bear market, Bitcoin broke the $8,000 price barrier for the first time since May 22. During this period, Bitcoin regained its dominance in the cryptocurrency market cap share, signaling a potential resurgence. But how did we get here? From a peak of 66% market dominance in late 2017 to a low of just 32.45% in early 2018, and then a rebound to over 52%, Bitcoin’s journey reflects deeper market psychology, investor behavior, and the evolving maturity of the crypto ecosystem.
This article explores the forces behind Bitcoin’s fluctuating dominance, the rise and fall of altcoins, and what these shifts mean for investors navigating today’s digital asset landscape.
The Rise and Fall of Bitcoin Dominance (2017–2018)
Bitcoin began the second half of 2017 on a strong note, with daily price records and widespread media coverage fueling public interest. By Q3 2017, the number of active cryptocurrency wallet addresses reached 17.2 million—jumping to 21.5 million by year-end. As adoption surged, so did Bitcoin’s dominance.
On December 7, 2017, Bitcoin dominance hit an all-time high of 66%, reflecting its central role in the market. However, as the bull run accelerated, a notable trend emerged: while Bitcoin’s price climbed toward $20,000, its market share began to decline.
By December 17—the day Bitcoin neared its $20,000 peak—its dominance had dropped below 50% for the first time since September. From December 19 onward, it continued to slide, reaching a low of 32.45% on January 13, 2018. This marked a dramatic shift in capital flow from Bitcoin to alternative cryptocurrencies.

Why Did Bitcoin’s Dominance Plummet?
Several factors contributed to this sharp decline:
1. Retail Investors Seek Affordable Entry Points
With Bitcoin trading near $20,000, many retail investors found it too expensive to enter. Instead, they turned to lower-priced alternatives like **Ripple (XRP)** under $1, Litecoin (LTC) under $100, and **Ethereum (ETH)** still below $1,000. These assets offered perceived affordability and higher upside potential.
2. The ICO Boom and Altcoin Surge
The late 2017 period saw a surge in initial coin offerings (ICOs) and new blockchain projects. Investors flocked to altcoins hoping to replicate early Bitcoin gains. Ethereum, Ripple, and Bitcoin Cash saw massive inflows:
- Ethereum: Market cap share rose from 9.92% (Dec 2017) to 18.54%
- Ripple: Jumped from 2.09% to 10.42%
- Bitcoin Cash: Increased from 5.38% to 6.15%
This diversification diluted Bitcoin’s dominance but reflected growing confidence in the broader blockchain ecosystem.
The Return of Bitcoin Dominance
By mid-2018, a reversal began. After months of bearish pressure, investors started pulling capital from struggling altcoins and reallocating it back into Bitcoin.
Key Drivers of the Rebound:
- Bear Market Reality Check: Many altcoins lost 80–95% of their value. Smaller projects with weak fundamentals collapsed.
- Flight to Safety: As volatility spiked, investors sought stability. Bitcoin, with its proven track record and liquidity, became the safe haven.
- Loss Aversion: Traders who entered altcoins at peak prices sought to "average down" by shifting into Bitcoin for more predictable performance.
On August 14, 2018, Bitcoin’s market cap share peaked at 54.59%, nearly doubling from its January low.
Market Psychology and Investment Strategy
Naeem Aslam, Chief Analyst at ThinkMarkets, noted that while Bitcoin’s dominance dipped during the altcoin frenzy, the trend was expected to reverse as investors matured in their approach.
A simulation by ThinkMarkets showed that investing $100,000 across the top five cryptocurrencies by market cap yielded a 68% quarterly return, outperforming random altcoin bets. This highlights a key insight: market cap-weighted strategies tend to be more stable and less speculative.
Vladislav Shabanov, Managing Partner at WhitePark Capital, echoed this view:
“Investors are now favoring high-quality digital assets with sustainable value. Bitcoin’s resilience during downturns reinforces its role as the core holding in any crypto portfolio.”

Is This Pattern Cyclical?
Yes—and history supports it.
- In 2014–2016, Bitcoin dominance hovered between 80–90%.
- As new projects like Ethereum gained traction in 2017, capital flowed into altcoins, reducing Bitcoin’s share.
- When speculation cooled and weaker projects failed, money rotated back into Bitcoin.
Shabanov explains:
“When Bitcoin enters a bull phase, its dominance typically declines as investors chase new opportunities. Conversely, during corrections, capital retreats to Bitcoin—a digital gold effect.”
This cyclical behavior suggests that dominance is not just a metric but a sentiment indicator.
Frequently Asked Questions (FAQ)
Q: What is Bitcoin dominance?
A: Bitcoin dominance measures Bitcoin’s market capitalization as a percentage of the total cryptocurrency market cap. It reflects investor preference between Bitcoin and altcoins.
Q: Why does Bitcoin dominance matter?
A: Rising dominance often signals risk-off behavior (bear markets), while falling dominance may indicate bullish sentiment toward innovation and altcoin growth.
Q: Does high Bitcoin dominance mean altcoins are dead?
A: No. High dominance usually precedes renewed interest in altcoins once confidence returns. It's part of a natural market cycle.
Q: Can Bitcoin dominance reach 70% or higher again?
A: It's possible during deep bear markets or regulatory uncertainty when investors seek safety. However, long-term diversification is likely as the ecosystem matures.
Q: Should I invest based on dominance trends?
A: Dominance should inform strategy but not dictate it. Use it alongside fundamentals, technical analysis, and macro trends.
Q: What causes sudden drops in Bitcoin dominance?
A: Typically driven by hype around new blockchain projects, DeFi booms, or major altcoin upgrades that attract speculative capital.

Final Thoughts
Bitcoin’s fluctuating dominance—from 66% to 33%, then rebounding to over 52%—is more than a statistic. It’s a reflection of evolving investor behavior, risk appetite, and the ongoing maturation of the digital asset class.
While altcoins will always play a role in driving innovation and capturing speculative interest, Bitcoin remains the anchor of stability in turbulent times. For long-term investors, understanding these cycles is crucial.
As the market continues to develop, expect dominance to ebb and flow—but never underestimate the gravitational pull of the original cryptocurrency.
Whether we’re entering a new bull phase or bracing for further consolidation remains to be seen. But one thing is clear: Bitcoin isn’t going anywhere.
