What to Expect from Ethereum Price as ETH/BTC Tests 2021 Bull Market Support

·

Ethereum (ETH) has seen a 5% drop in the past 24 hours amid a broader downturn in the cryptocurrency market. Despite this pullback, a key metric—the ETH/BTC ratio—has dipped to test a critical support level last seen during the explosive 2021 bull run, which previously triggered a rally exceeding 4,000%. As this ratio begins to stabilize and show signs of recovery, investors are asking: Could Ethereum be on the verge of a major resurgence? And is a return to $4,000 within reach?

Currently, ETH is trading at $2,513, with recent volatility threatening to erase the gains made earlier in 2025. However, market sentiment remains resilient. Institutional interest is shifting increasingly toward Ethereum, suggesting that smart money may be accumulating ahead of a potential breakout.

The Significance of the ETH/BTC Ratio

The ETH/BTC trading pair is more than just a price chart—it's a powerful indicator of market leadership. When ETH outperforms BTC, the ratio rises, signaling growing confidence in Ethereum’s ecosystem, scalability upgrades, and institutional adoption.

Right now, the ETH/BTC ratio has fallen to 0.017, a level that served as strong support during the 2021 bull market. Historically, bounces from this zone have preceded massive rallies in Ethereum’s value. The current setup suggests a similar pattern may be unfolding.

Since bottoming near 0.017, the ratio has begun forming a steady upward trend. For this bullish momentum to confirm and potentially ignite a new bull cycle, the ratio must first break past a key resistance at the 61.8% Fibonacci retracement level of 0.0422.

If that hurdle is cleared, technical models suggest the ratio could climb toward 0.082—its highest point since September 2022—representing roughly a 2x increase from current levels.

However, caution remains warranted. The ADX (Average Directional Index) line is sloping downward, indicating weakening trend strength. This means that while upside potential exists, traders should watch for confirmation—such as sustained volume and price action—before assuming a full bull market is underway.

Key Price Levels to Watch in Ethereum

While the ETH/BTC ratio provides macro-level insight, the ETH/USDT chart reveals crucial tactical levels that could determine short- to mid-term price direction.

Ethereum is currently defending a critical support zone between $2,400 and $2,550. This range has repeatedly acted as a floor during previous corrections. A successful bounce from this area could set the stage for a strong recovery.

The first major resistance lies at the 200-day Simple Moving Average (SMA), currently around $2,669. A confirmed breakout above this level would signal a shift in long-term momentum and could validate bullish expectations.

Should ETH sustain momentum past $2,669, the next target zone lies between **$3,800 and $3,900**. Clearing this range would likely trigger strong buying pressure, potentially propelling Ethereum past the psychologically significant **$4,000** mark.

Bull Flag Pattern Adds to Optimism

Technical analysis reveals the formation of a bull flag pattern on Ethereum’s daily chart. These patterns typically form after a sharp upward move followed by consolidation—like a “pause” before the next leg higher.

A breakout from this bull flag—especially on increasing volume—could accelerate price action toward $4,000. Given that similar patterns preceded major rallies in 2021 and 2023, traders are watching this setup closely.

Can History Repeat? A 2x Rally on the Horizon?

While a 4,000% rally like in 2021 may be unrealistic given Ethereum’s current market cap—now over $300 billion—a more modest but still substantial 2x increase is within reason if macro conditions improve and on-chain activity surges.

A doubling from current levels would push ETH well beyond $5,000. Even a more conservative 1.5x move would bring it to $3,750–$4,000, aligning with growing optimism around Ethereum’s role in decentralized finance (DeFi), NFTs, and Layer-2 scaling solutions.

Factors supporting this outlook include:

These fundamentals suggest that Ethereum is not just recovering—it may be repositioning itself as the leading asset in the altcoin ecosystem.

Frequently Asked Questions (FAQs)

Q: What does the ETH/BTC ratio tell us about Ethereum’s price potential?
A: The ETH/BTC ratio measures Ethereum’s strength relative to Bitcoin. A rising ratio indicates ETH is outperforming BTC, often signaling the start of an altcoin-dominated bull run. Testing long-term support at 0.017 and rebounding could precede significant gains.

Q: Can Ethereum reclaim $4,000?
A: Yes—provided it breaks above the 200-day SMA at $2,669 and maintains bullish momentum. Support at $2,400–$2,550 remains intact, and technical patterns like the bull flag suggest upside potential.

Q: Why is institutional interest shifting from Bitcoin to Ethereum?
A: Institutions are increasingly drawn to Ethereum’s real-world utility—smart contracts, DeFi, staking yields, and enterprise adoption. Unlike Bitcoin’s store-of-value narrative, Ethereum offers programmable value and yield-generating opportunities.

Q: What resistance levels should traders watch?
A: Key resistance sits at $2,669 (200-day SMA). Beyond that, $3,800–$3,900 is the next major zone. A close above these levels could trigger accelerated buying.

Q: Is on-chain data supporting the bullish case?
A: Yes—metrics like rising active addresses, increasing gas usage, and growing staking participation all point to strong network fundamentals beneath the price action.

Q: Could macroeconomic factors impact Ethereum’s rally?
A: Absolutely. Lower interest rates, dollar weakness, and increased crypto adoption in traditional finance could all serve as catalysts. Conversely, regulatory uncertainty or risk-off sentiment may delay recovery.
