In recent weeks, Bitcoin has once again captured the spotlight with a dramatic surge in value. Data from major Chinese exchanges like OKCoin and Huobi show that since August 2, Bitcoin rose for 14 out of 15 trading days, gaining nearly 10,000 yuan and peaking around 29,000 yuan. This rally pushed Bitcoin to new highs and reignited investor interest across the digital asset landscape.

Yet, while Bitcoin climbs, other top cryptocurrencies like Ethereum, Litecoin, and Ripple have failed to follow suit. In fact, many have declined, failing to reclaim previous resistance levels. This divergence is unusual—historically, major cryptocurrencies tend to move in tandem due to shared market sentiment and investor behavior. So why is Bitcoin breaking away?
The Growing Dominance of Bitcoin
To understand this trend, consider market capitalization data from CoinMarketCap. As of August 14, 2017, the total market cap of all cryptocurrencies stood at approximately $140 billion. Bitcoin alone accounted for $71.8 billion—over 51% of the entire market.
Compare that to June 28, 2017: total market cap was $106.1 billion, with Bitcoin at $42.3 billion—just 39.9%. In just seven weeks, the overall market grew by $33.9 billion, but **Bitcoin contributed $29.5 billion** of that increase. When factoring in Bitcoin Cash (BCH), which launched on August 1 with a nearly $5 billion market cap at the time, the picture becomes even clearer.
This implies that excluding Bitcoin and BCH, the rest of the crypto market actually lost value during this period. Despite Bitcoin’s 70% surge in market cap, Ethereum and Litecoin remained stagnant or declined—a rare and telling decoupling.
Two Key Factors Behind Bitcoin’s Surge
While broad trends like blockchain adoption benefit the entire crypto space, they don’t explain Bitcoin’s unique performance. The divergence points to factors specific to Bitcoin itself. Two primary drivers stand out:
1. SegWit Activation Boosts Investor Confidence
The successful locking-in of the Segregated Witness (SegWit) protocol has been a major catalyst. For years, Bitcoin faced criticism for its limited transaction throughput compared to platforms like Ethereum. SegWit addresses this by changing how data is stored, effectively increasing block capacity and paving the way for Layer 2 solutions like the Lightning Network.
Even rumors of SegWit deployment sparked rallies earlier in May 2017—Bitcoin rose for nine out of ten days twice within a month. When SegWit was finally locked in during August, it marked a realization of long-held expectations, triggering another wave of buying pressure.

This wasn’t just technical progress—it was psychological. After prolonged debates and network congestion issues, the community saw SegWit as a win for scalability and innovation, reinforcing faith in Bitcoin’s long-term viability.
2. ICO Boom Drives Demand for Base Cryptocurrencies
The second factor is the explosive growth of Initial Coin Offerings (ICOs). Throughout 2017, ICOs became a dominant fundraising method in the blockchain space. According to Coindesk’s ICO tracker:
- April 2017: $104 million raised
- May: $232 million (+123%)
- June: $462 million (+99%)
- July: $574 million (+24%)
These figures highlight a surging demand for cryptocurrencies used in token sales—primarily Bitcoin and Ethereum. Investors needed BTC or ETH to participate, creating upward pressure on both assets.
However, while Bitcoin surged past prior highs, Ethereum remained stuck near 2,000 yuan—well below its earlier peak near 3,000 yuan. This suggests that while ICOs boosted demand broadly, Bitcoin absorbed disproportionate gains, possibly due to its perceived stability and status as "digital gold."
But Is the Foundation Solid?
Despite these supportive factors, concerns remain about whether the rally is built on solid ground.
The ICO-driven demand, while real, seems insufficient to justify Bitcoin’s massive price jump. A few hundred million dollars in monthly ICO funding pales in comparison to Bitcoin’s tens-of-billions-dollar valuation increase. Ethereum’s flat performance further indicates that the broader ecosystem isn’t experiencing equivalent momentum.
Instead, much of Bitcoin’s rise appears tied to Sentiment around SegWit, rather than immediate utility gains. And here lies a deeper risk: network fragmentation.
The Risk of Chain Splits Looms Large
SegWit’s adoption was part of a broader agreement known as the New York Agreement (NYA), which promised a subsequent 2MB block size increase—SegWit2x. Miners supported this path, expecting improved scalability.
However, the Core development team has consistently opposed hard forks and direct block expansions. In fact, they planned to release Bitcoin Core 0.15.0, which would not support SegWit2x nodes.
This sets up a potential chain split: if miners push forward with larger blocks while Core nodes reject them, the network could bifurcate into two chains—one with 2MB blocks, one without.
SegWit2x developers announced plans for November 2017 activation, with over 90% of mining power reportedly backing it. But without consensus, a split becomes likely—repeating the Bitcoin Cash fork earlier that year.

So is SegWit really cause for celebration? Or is it simply fueling another speculative bubble?
The Role of Speculation and Market Psychology
Ultimately, speculative behavior may be the strongest explanation for Bitcoin’s outsized gains.
While real developments like SegWit and ICO activity provide narrative support, they don’t fully justify the magnitude of the rally. Instead, investor psychology—fear of missing out (FOMO), herd behavior, and over-optimism—appears to be driving prices beyond fundamentals.
Many enthusiasts argue that “Bitcoin will one day be worth a house—just buy and hold.” But as Warren Buffett reminds us, it’s not just what you buy, but at what price. Even great assets can become poor investments when purchased at inflated valuations.
Bitcoin certainly has strong foundational value—decentralization, scarcity, growing adoption—but timing matters. In volatile markets, few investors truly “hold through the storm” when prices swing wildly.
Frequently Asked Questions (FAQ)
Q: Why is Bitcoin rising while other cryptos fall?
A: Bitcoin’s recent surge is largely driven by SegWit activation and strong investor sentiment, while altcoins like Ethereum and Litecoin haven’t seen equivalent catalysts. Additionally, market concentration means Bitcoin often absorbs disproportionate capital during rallies.
Q: Does the ICO boom benefit Bitcoin?
A: Yes—many ICOs accept Bitcoin as payment, increasing demand. However, Ethereum is more commonly used in ICOs due to smart contract functionality, so Bitcoin’s price link to ICOs is more indirect.
Q: Could Bitcoin split again after SegWit?
A: Yes—SegWit2x aimed to increase block size to 2MB and could have caused a hard fork if consensus wasn’t reached. While SegWit passed smoothly, future upgrades remain contentious.
Q: Is Bitcoin in a bubble?
A: Some analysts believe short-term gains exceed fundamental drivers, suggesting speculative elements are present. However, long-term value depends on adoption, network security, and macroeconomic trends.
Q: Should I invest in Bitcoin during a rally?
A: Timing the market is difficult. It’s wise to assess valuation metrics and personal risk tolerance before investing. Dollar-cost averaging can help mitigate volatility risks.
Q: What are core keywords for this article?
A: Key SEO terms include Bitcoin price surge, Ethereum vs Bitcoin, SegWit activation, cryptocurrency market cap, ICO demand, Bitcoin Cash fork, crypto speculation, and blockchain scalability.
In conclusion, Bitcoin’s recent rally reflects a mix of technical progress and market psychology. While real innovations like SegWit provide justification for optimism, the lack of broader altcoin strength raises questions about sustainability. As always in crypto—caveat emptor.
