Ethereum (ETH) has been trailing significantly behind Bitcoin (BTC) in recent months, raising concerns among investors and traders alike. On September 18, the ETH/BTC trading pair hit its lowest level in over three and a half years—the first time since 2021 that Ether has been this weak relative to Bitcoin. This underperformance has sparked a critical question: Is this dip a buying opportunity, or will Ethereum continue to lose ground against the dominant cryptocurrency?
While Bitcoin has been consolidating within a tight range, many analysts believe it’s poised for a breakout in the fourth quarter of 2025, potentially reaching new all-time highs. In contrast, Ethereum remains far from its peak, and market sentiment suggests limited near-term upside. According to Polymarket, the world’s largest prediction market, there’s an 85% chance that Ethereum will not reach a new all-time high in 2025.
Despite these bearish signals, there are glimmers of hope for ETH bulls.

Technical Outlook: A Battle Between Bulls and Bears
The long-term weekly chart of the ETH/BTC pair reveals a symmetrical triangle pattern, typically signaling indecision between buyers and sellers. In this formation, bulls are defending the lower trendline support, while bears are holding firm at resistance.
Currently, both the 50-day and 200-day moving averages are sloping downward, indicating sustained bearish momentum. Meanwhile, the Relative Strength Index (RSI) is hovering near oversold territory—another sign that selling pressure remains strong.
However, history shows that such extended consolidation phases often precede major breakouts. If price bounces from the lower boundary of the triangle and pushes above the declining moving averages, it could signal a shift in momentum. A confirmed breakout above the triangle's upper resistance could target 0.18 BTC, surpassing the previous high of 0.15 BTC.
This would represent a bullish reversal of nearly 20% from current levels—potentially rewarding early adopters who recognize the pattern.
Short-Term Trends: Signs of a Potential Reversal
Zooming into the daily chart, the ETH/BTC pair has been trading within a descending channel, characterized by lower highs and lower lows—a classic bearish structure.
Yet, there are emerging technical hints that the downtrend may be losing steam:
- The 20-day exponential moving average (EMA) at around 0.04 BTC has started to flatten.
- The RSI is showing a positive divergence, meaning price is making new lows while momentum is not confirming them—often a precursor to a reversal.
These developments suggest that selling pressure might be easing. A decisive close above the 50-day simple moving average (SMA), also near 0.04 BTC, could act as a trigger for short-term bulls to re-enter the market.
More importantly, a sustained breakout above the upper boundary of the descending channel would signal a potential trend reversal. Such a move could attract algorithmic traders and systematic funds looking for momentum shifts in major crypto pairs.
Key Resistance and Support Levels to Watch
For traders monitoring the ETH/BTC pair, several critical price levels will determine the next directional move:
- Immediate Resistance: 0.042 BTC – Break above this level could accelerate buying interest.
- Major Resistance: Upper boundary of the symmetrical triangle (~0.048 BTC) – A breakout here could confirm bullish continuation.
- Immediate Support: 0.038 BTC – A break below this level invalidates short-term bullish assumptions.
- Channel Support: ~0.032 BTC – Long-term buyers may step in near this zone if selling continues.
If price falls below 0.038 BTC, the positive divergence and flattening EMA would become less reliable, increasing the risk of further downside toward the channel’s lower bound.
Why Is Ethereum Underperforming?
Several macro and ecosystem-specific factors explain ETH’s lag behind BTC:
- Bitcoin Dominance Surge: Amid regulatory clarity and spot Bitcoin ETF approvals, institutional capital has flowed heavily into BTC, boosting its dominance.
- Delayed Ethereum Catalysts: While Ethereum remains the leading smart contract platform, anticipated upgrades like full danksharding or widespread EigenLayer adoption have yet to materialize at scale.
- Market Risk Aversion: During uncertain macroeconomic periods, investors often favor Bitcoin as "digital gold," leaving altcoins like Ethereum behind.
Still, Ethereum maintains strong fundamentals:
- Over 60% of decentralized applications (dApps) are built on its network.
- Layer-2 solutions like Arbitrum and Optimism continue growing rapidly.
- Staking participation remains high, with over 30 million ETH staked as of mid-2025.

Can Ethereum Outperform Bitcoin by Year-End?
Bitwise Asset Management’s Chief Investment Officer recently suggested that Ethereum could be “a potential contrarian bet by year-end.” This view hinges on several assumptions:
- A post-halving rotation from Bitcoin to high-quality altcoins.
- Renewed developer activity and user growth on Ethereum L2s.
- Potential approval of spot Ethereum ETFs in late 2025.
If these catalysts align, capital could begin rotating into ETH, driving relative strength against BTC.
Historically, after periods of prolonged underperformance, Ethereum has delivered strong catch-up rallies—especially during bull markets fueled by DeFi or NFT booms.
FAQ: Common Questions About ETH/BTC Performance
Q: Why is the ETH/BTC ratio important?
A: The ETH/BTC pair measures Ethereum’s strength relative to Bitcoin. An increasing ratio means ETH is outperforming BTC, often signaling broad altcoin strength and risk-on market behavior.
Q: What does a low ETH/BTC value mean?
A: A declining ratio suggests investors are favoring Bitcoin over Ethereum, commonly seen during risk-off periods or when BTC-specific narratives dominate (e.g., ETF inflows).
Q: Can Ethereum ever surpass its previous high against Bitcoin?
A: Yes—technically, the symmetrical triangle pattern projects a target of 0.18 BTC, well above the prior high of 0.15 BTC. Whether it reaches that level depends on macro conditions and Ethereum-specific catalysts.
Q: Should I buy ETH now if BTC is performing better?
A: It depends on your strategy. If you believe in Ethereum’s long-term utility and expect a rotation into altcoins, current weakness may present a strategic entry point.
Q: What events could trigger an ETH/BTC rally?
A: Key triggers include spot ETH ETF approvals, major network upgrades, increased L2 adoption, or a broader market shift toward risk assets.
Final Thoughts: Patience May Pay Off
While Ethereum’s current performance against Bitcoin appears bleak, technical patterns suggest a potential turnaround is possible. The formation of a long-term symmetrical triangle, combined with early signs of momentum stabilization, sets the stage for a meaningful move—up or down.
For contrarian investors, now may be the time to assess whether Ethereum’s fundamentals justify positioning ahead of potential catalysts in late 2025.
