The current market cycle has left many investors wondering: why is Ethereum (ETH) underperforming despite Bitcoin’s (BTC) strong rally? And more importantly, when will ETH finally catch up?
In this deep dive, we’ll analyze Ethereum’s on-chain data to uncover the real story behind its lackluster performance. Using objective metrics like exchange flow ratios and network activity, we’ll assess whether ETH still has momentum—and what conditions must be met for a true breakout.
This isn’t about hype or narratives. It’s about data-driven insights that reveal where capital is flowing and what it means for ETH’s future.
Why Is Ethereum Underperforming in This Cycle?
Ethereum has long been considered the second pillar of the crypto market, often following Bitcoin’s lead with a powerful surge of its own. But this cycle feels different.
Despite Bitcoin breaking past $73,000 and ETF approvals fueling massive inflows, Ethereum has failed to generate similar momentum—even after its own spot ETF was approved in 2025.
So what’s going wrong?
To answer that, we need to look beyond price charts and examine on-chain behavior, particularly two key indicators:
- Exchange flow ratio (ETH vs. BTC)
- On-chain activity levels
These metrics help us understand whether institutional and retail capital are actually rotating into ETH—or staying put in BTC.

Exchange Flow Ratio: A Clear Sign of Weak Capital Interest
One of the most telling signs of market sentiment is how much ETH is moving in and out of exchanges compared to BTC.
Here’s how it works:
- Inflows = potential selling pressure (supply)
- Outflows = potential buying interest (demand)
- The ratio between ETH and BTC flows shows where capital is focused
Let’s compare previous cycles with today’s data.
2021 Bull Run: ETH Followed BTC With Strong Momentum
During the 2021 cycle:
- When BTC led from January to April, ETH’s exchange flow was around 30% of BTC’s
- As BTC peaked and pulled back in April–May, ETH stepped up—its flow ratio jumped to 50%
- After the May 19 crash, ETH held strong. At one point, its exchange flow matched BTC’s 1:1, showing strong conviction
This capital rotation confirmed that investors were shifting from BTC to ETH during the mid-cycle phase—a classic sign of a healthy bull market.
2025 Cycle: No Meaningful Rotation Into ETH
Fast forward to 2023–2025:
From October 2023 to March 2024, BTC led again—driven by spot ETF anticipation. During this time, ETH’s exchange flow was only 15% of BTC’s on key days.
Even at peak FOMO in March 2024 (BTC hitting $73K), ETH’s flow ratio only reached 25%, far below the 50% seen in 2021.
And here’s the kicker: after ETH’s spot ETF approval, flows only rose to 34%—still well short of historical norms.
As of October 2025, the ratio hovers around 35%, similar to levels seen in late 2023—barely any improvement despite major catalysts.

This tells us one thing clearly: the market isn’t rotating into ETH like it did before. Even with ETF approval, institutional appetite remains lukewarm.
On-Chain Activity: Is the Ethereum Ecosystem Still Thriving?
Strong price action requires strong fundamentals—and for Ethereum, that means network usage.
We measure on-chain vitality through three core metrics:
- Active addresses (user engagement)
- Transaction count (network throughput)
- Transfer volume in USD (capital movement)
Historical Highs: 2018 & 2021
Back in 2018 and 2021:
- Active addresses surged during bull phases
- Transaction volume hit records—$18 billion in Jan 2018**, **$155 billion in May 2021
- DeFi and NFT booms drove real economic activity
These weren’t just speculative spikes—they reflected real usage growth.
Current Trends: Activity Is Declining
Since March 2025:
- Active addresses have been steadily declining
- Transaction count briefly matched 2021 highs—but value transferred was only $67 billion, less than half of previous peaks
- Most transactions appear to be small-scale or bot-driven
This suggests that while some users are active, large-cap investors aren’t deploying capital on-chain. Without big money moving ETH, prices struggle to break out.
Was the Shift to Proof-of-Stake a Turning Point?
In September 2022, Ethereum completed “The Merge,” transitioning from Proof-of-Work (PoW) to Proof-of-Stake (PoS).
While this reduced energy consumption and introduced yield opportunities, it may have also altered investor perception.
Notably:
- Starting in July 2022—just before The Merge—ETH’s exchange flow ratio began diverging from BTC’s
- Since then, the gap has widened consistently
- Even with PoS staking rewards, capital hasn’t returned in force
Some argue that moving away from mining removed a key ideological alignment with Bitcoin. Others believe Ethereum’s increasing centralization risks have made it less attractive as “digital gold.”
Whatever the reason, the data shows a structural shift in capital preference post-Merge—and so far, it hasn't reversed.
When Will Ethereum Finally Surge?
Based on historical patterns and current data, here are the conditions that must align for ETH to enter a sustained uptrend:
✅ 1. Exchange Flow Ratio Reaches 50% or Higher
Until ETH’s daily exchange inflows/outflows reach at least half of BTC’s, we can’t confirm meaningful capital rotation. Right now, it's stuck at ~35%.
✅ 2. Sustained Growth in Active Addresses
We need to see a consistent upward trend in unique addresses interacting with the network—not just short-term spikes.
✅ 3. Rising Transaction Value (Not Just Count)
High transaction counts mean little if they’re low-value swaps or arbitrage bots. We need real-dollar volume approaching $100B+ regularly.
Only when all three conditions are met should investors consider ETH positioned for a major move.
Frequently Asked Questions
Q: Has Ethereum lost its relevance in the crypto market?
Not necessarily. Ethereum remains the dominant platform for DeFi, NFTs, and Web3 innovation. However, market relevance doesn’t always translate to price strength, especially if capital prefers BTC.
Q: Can ETH rally without surpassing BTC in flows?
Yes—but it would likely be short-lived. Without broad capital adoption, any rally may fizzle quickly. Sustainable growth requires real money moving in.
Q: Does the ETF approval still matter if flows are weak?
It matters structurally—it opens doors for institutional access. But approval alone doesn’t guarantee demand. Execution and timing matter just as much.
Q: Could upcoming upgrades like EIP-4844 or Proto-Danksharding spark a rally?
They could boost scalability and reduce fees, which benefits developers and users. But unless these translate into higher on-chain value transfer, their impact on price may be limited.
Q: Should I sell ETH and go all-in on BTC?
That depends on your strategy. BTC is clearly leading this cycle. But a diversified portfolio including ETH may still make sense—if you wait for stronger confirmation signals.
Q: What’s the best way to track these metrics in real time?
Use blockchain analytics platforms that monitor exchange flows, active addresses, and transaction volumes. Many provide alerts when key thresholds are hit.

Final Thoughts: Patience Over Hype
Ethereum isn’t broken—but it’s not leading either.
The data shows a clear lack of institutional and large-scale retail interest compared to previous cycles. Despite major milestones like ETF approval and protocol upgrades, capital remains cautious.
For now, Bitcoin continues to dominate as the primary destination for crypto investment.
But markets evolve.
If Ethereum can reignite developer activity, drive real-world usage, and attract meaningful capital flows—especially when BTC enters consolidation—we could finally see that long-awaited catch-up rally.
Until then, watch the data—not the noise.
