Key Takeaways
- Ethereum’s upside remains tied to Bitcoin’s stability.
- While Coinbase and others are pushing for action on quantum, firms like Galaxy and ARK say risks are long-term and manageable.
- Ethereum’s fundamentals are strengthening.
A renewed push by Coinbase CEO Brian Armstrong to address potential quantum computing risks in Bitcoin is drawing close attention from Ethereum investors, igniting debate on how intertwined the fortunes of the two largest cryptos actually are.
Armstrong said he would begin dedicating personal time to the issue, writing on X that “we all need to solve it sooner rather than later.”
The comments come as some analysts still believe that, for Ethereum to thrive, Bitcoin’s success is paramount.
Armstrong Steps Into Bitcoin Quantum Concerns
Coinbase CEO Philip Martin highlighted on X recent research from Google and Caltech as a signal that the crypto industry must prepare for so-called cryptographically relevant quantum computers (CRQCs), which could, in theory, break current encryption methods.
While noting that post-quantum cryptography solutions already exist, Martin said Bitcoin lacks a clear migration roadmap and urged coordinated action across developers and companies.
Coinbase, he added, is convening industry participants to accelerate efforts.
“Going to start spending time on this personally – seems like we all need to solve it sooner rather than later,” Armstrong wrote in response to his colleague’s post.
Ethereum Investors See Bitcoin Stability As Critical
Rather than viewing Bitcoin’s challenges as isolated, many Ethereum investors have started to argue that risks to Bitcoin could ripple across the entire digital asset market.
Some ETH-focused market participants say a sharp decline in Bitcoin—whether triggered by a real quantum attack or preemptive market fears—could weigh heavily on Ethereum’s dollar price.
“The real quantum risk to ETH isn’t quantum breaking Ethereum,” one crypto user wrote on X.
“It’s quantum breaking BTC first and dragging everything down with it.”
Others argue that Ethereum’s path to multi-trillion-dollar valuations depends on a combination of factors tied to Bitcoin’s strength:
Rising Bitcoin price.
Improving ETH/BTC ratios.
Gradual capital rotation from Bitcoin into Ethereum.
“Brian’s new personal involvement in leading Bitcoin through its quantum crisis is crucial and bullish,” the X user wrote.
“Hope to see Tether’s Paolo join this effort,” they added.
Quantum Risks Torn
The recent wave of concerns comes as Google flagged 2029 as a key milestone for transitioning to post-quantum cryptography, warning that future quantum machines could eventually break widely used encryption and digital signature systems.
Even so, there is little consensus across the industry on how imminent or severe the threat may be.
Galaxy Digital characterizes the risk as credible but limited in scope.
In its view, only Bitcoin tied to exposed public keys—such as funds in older wallets, reused addresses or certain custodial structures—would be vulnerable in a quantum scenario.
At the same time, the firm emphasized that Bitcoin’s architecture offers partial safeguards.
“Bitcoin’s design provides a degree of protection against quantum attacks because public keys are not exposed until coins are spent,” Galaxy Research said.
Galaxy also rejected the idea that the ecosystem is unprepared, pointing to ongoing technical work.
“Work on quantum resistance is already substantial and accelerating across the ecosystem,” it said, highlighting proposals like BIP 360 as evidence that mitigation efforts are underway.
Despite governance hurdles, the firm said incentives across developers, miners and users remain aligned to ensure the network evolves in time.
ARK Invest echoed a similar long-term framing, arguing that current quantum systems are still far from capable of breaking Bitcoin’s cryptography.
Existing machines, it said, remain in the “Noisy Intermediate-Scale Quantum” (NISQ) phase, constrained by error rates and limited computational scale.
ARK estimates that while a meaningful portion of Bitcoin—potentially up to 35%—could be exposed under future conditions, any transition would likely unfold gradually, giving the network time to adapt and migrate funds.
Others, however, dismiss the threat altogether.
Michael Saylor, executive chairman of Strategy and a prominent Bitcoin advocate, has argued that quantum computing would ultimately reinforce Bitcoin’s resilience.
“The network upgrades, active coins migrate, lost coins stay frozen,” Saylor said.
Bitcoin–Ethereum Relationship
Asset manager VanEck recently described Bitcoin and Ethereum as offering “distinct but complementary value propositions.”
Bitcoin is widely treated as a store of value, benefiting from scarcity, growing institutional adoption and its narrative as a hedge against inflation.
Ethereum, by contrast, is positioned as infrastructure for decentralized applications, underpinning sectors such as decentralized finance (DeFi), tokenized assets and digital ownership.
Despite their differences, VanEck noted that many investors hold both assets to balance risk and exposure to different aspects of the crypto economy.
“Rather than an either/or decision, many portfolios include both to balance risk and utility,” it wrote.
Analysts Say Bitcoin Gains Could Lift Ethereum
Several analysts argue that Bitcoin’s long-term success is likely to benefit Ethereum and other digital assets.
Fundstrat’s Tom Lee has emphasized the importance of the ETH/BTC ratio in determining Ethereum’s upside.
In projections shared with investors, Lee said that if Bitcoin were to reach $250,000, Ethereum could trade between $12,000 and $22,000 depending on historical ratio ranges.
Lee, who has described Ethereum as “the future of finance,” suggested even higher valuations are possible under more aggressive scenarios tied to Bitcoin’s growth.
Ethereum Rebounds But Faces Resistance
It comes as Ethereum has shown early signs of recovery after a recent pullback, though analysts say the broader trend remains uncertain.
Victor Olanrewaju, an analyst at CCN, said ETH rebounded from near the $1,700 support zone to around $2,101, indicating “early signs of strength” following a sharp decline.
“Despite this recovery, the broader structure still reflected a lingering downtrend,” he noted, pointing out that Ethereum remains below key Fibonacci resistance levels, including the 0.236 level near $2,495.
Short-term sentiment has improved, however, with buyers stepping in to stabilize price action.
Olanrewaju highlighted that momentum indicators such as the Money Flow Index (MFI) have trended higher toward 60, suggesting increasing capital inflows.
Still, he cautioned that the recovery lacks strong conviction.
“Ethereum approached a critical decision point,” Olanrewaju said.
“If buyers maintain pressure and push ETH’s price above the $2,200 resistance zone, ETH will likely move toward $2,400 and then test the $2,500 region.”
Failure to break higher could see prices retreat toward $2,000 support, with the risk of deeper losses if momentum fades, he added.
Ethereum’s Tokenization Growth Highlights Bitcoin Relationship
Beyond short-term price movements, Ethereum’s fundamental outlook continues to be supported by its growing dominance in tokenized assets—though this strength also helps explain why some investors see Bitcoin’s stability as critical.
According to data cited by CCN from Token Terminal, Ethereum controls around 61% of the tokenization market, with approximately $206 billion in settled value over the past year, expanding roughly 40% year-on-year.
That lead highlights Ethereum’s role as the primary infrastructure layer for tokenizing real-world assets such as U.S. Treasuries and private credit.
The network’s ability to enable programmable ownership, near-instant settlement and global access has driven adoption among both institutional and retail users.
However, analysts say this growing importance also ties Ethereum more closely to the broader crypto market’s stability—where Bitcoin remains the dominant anchor.
As the largest and most widely held digital asset, Bitcoin often sets the tone for liquidity, and risk appetite.
Institutional adoption further links the two. Many investors allocate to both Bitcoin and Ethereum as complementary exposures.
This is because Bitcoin’s performance often promotes capital flows into Ethereum.
In that context, Ethereum’s expanding role in tokenization and financial infrastructure may actually increase its sensitivity to systemic risks tied to Bitcoin.
