Bitcoin’s Three Unsolved Problems Could Hand Ethereum a Long-Term Structural Advantage

TLDR:

  • Bitcoin lacks a central body to coordinate a quantum-proof upgrade, making the transition socially and technically difficult.
  • Around 1.7 million inaccessible BTC face quantum theft risk, forcing miners to choose between freezing or losing those coins.
  • Bitcoin’s declining block subsidy raises long-term security concerns, as transaction fees are unlikely to fill the funding gap.
  • Ethereum’s proof-of-stake model and Foundation coordination give it structural advantages over Bitcoin in security and adaptability.

Bitcoin’s long-term viability is under scrutiny as three structural problems emerge around quantum resistance, inaccessible coins, and economic security.

These concerns have resurfaced in crypto discussions, with analysts comparing the two largest networks. While Bitcoin remains the dominant digital asset by market cap, some observers believe Ethereum’s design choices may position it more favorably over time.

The debate has reignited questions about governance, adaptability, and the future balance of power between the two networks.

Bitcoin’s Quantum and Governance Problems Draw Fresh Attention

Bitcoin’s decentralized structure, often praised as a strength, may complicate its quantum upgrade. Unlike Ethereum, Bitcoin lacks a central coordinating body to manage such a technical shift. Its conservative culture makes large-scale protocol changes socially difficult to push through.

Crypto analyst John Galt raised this concern directly on X, noting that “Bitcoin has no central entity to coordinate the quantum upgrade.” He added that Bitcoin’s culture makes big changes “socially very difficult.” This cultural resistance could slow necessary adaptations.

The inaccessible coin problem adds another layer of complexity. Around 1.7 million BTC are presumed lost or inaccessible, making them vulnerable once quantum computing matures. Moving these coins to quantum-proof addresses requires owner action, which is impossible for lost holdings.

This creates a binary dilemma: miners could freeze those coins, or quantum hackers could eventually claim them. Either outcome risks fracturing the Bitcoin community. Galt compared the potential fallout to the block size war, which split the network years ago.

Ethereum’s Design Offers Structural Solutions, Analysts Argue

Ethereum’s approach to quantum readiness differs significantly from Bitcoin’s. The Ethereum Foundation can coordinate protocol upgrades more efficiently. Additionally, far fewer ETH are presumed inaccessible, reducing the quantum vulnerability gap.

On the economic security front, Bitcoin’s block subsidy will continue declining over successive halving cycles. Transaction fees alone are not expected to replace that subsidy reliably. This raises long-term questions about miner incentives and network security.

Ethereum, meanwhile, transitioned to proof-of-stake, which removes dependence on mining subsidies entirely. Galt noted that “the economic security problem is solved with PoS and effective tail emissions.” This structural difference could matter more as both networks age.

Culturally, the two ecosystems are also shifting in opposite directions, according to Galt. He pointed to Michael Saylor’s growing influence as a force reshaping Bitcoin’s culture toward institutional conservatism. By contrast, the recent Ethereum Foundation manifesto signaled a more cypherpunk direction.

Galt concluded that these combined factors could drive ETH to gain ground against BTC in the coming years. He framed the current ETH valuation as comparable to buying BTC at $12,200, citing relative market caps. Whether that comparison holds will depend on how each network navigates these structural pressures.

Aave’s TVL Falls $8B After $293M Kelp DAO Hack

Aave’s TVL Falls $8B After $293M Kelp DAO Hack

Total value locked on decentralized lending protocol Aave dropped by nearly $8 billion over the weekend after hackers behind the $293 million Kelp DAO exploit borrowed funds on Aave, leaving roughly $195 million in “bad debt” on the protocol and triggering withdrawals.

Data from DeFiLlama shows that Aave’s TVL fell from about $26.4 billion to $18.6 billion by Sunday, losing the top spot as the largest DeFi protocol. 

Aave v3’s lending pools for USDt (USDT) and USDC (USDC) are now at 100% utilization, meaning that more than $5.1 billion worth of stablecoins cannot be withdrawn until new liquidity arrives or borrows are repaid.

Aave’s TVL fall shows how rapidly risk from a single security incident can spread throughout the broader, interconnected DeFi lending market, potentially leading to a severe liquidity crisis.

The incident began on Saturday when hackers stole 116,500 Kelp DAO Restaked ETH (rsETH) tokens worth about $293 million from Kelp DAO’s LayerZero-powered bridge and used them as collateral on Aave v3 to borrow wrapped Ether (wETH).

Crypto analytics platform Lookonchain said the move created about $195 million in “bad debt” on Aave, which contributed to the Aave (AAVE) token tanking nearly 20% from $112 on Saturday at 6:00 pm UTC to $89.5 about 25 hours later. 

Lookonchain noted that some of the largest crypto whales to withdraw funds from Aave were the MEXC crypto exchange and Abraxas Capital at $431 million and $392 million, respectively.

Several crypto networks and protocols tied to rsETH or the LayerZero bridge have paused use of the bridge until the problem is resolved, including DeFi platform Curve Finance, stablecoin issuer Ethena and BitGo’s Wrapped Bitcoin (WBTC).

Aave has frozen several rsETH, wETH markets

Shortly after the Kelp DAO exploit, Aave said it froze the rsETH markets on both Aave v3 and v4 to prevent any suspicious borrowing and later stated that rsETH on Ethereum mainnet remains fully backed by underlying assets.

WETH reserves also remain frozen on Ethereum, Arbitrum, Base, Mantle and Linea, Aave said.

This incident marks the first significant stress test of Aave’s “Umbrella” security model, which was introduced in June 2025 to provide automated protection against protocol bad debt while enabling users to earn rewards.

Earlier this month, the Bank of Canada found that Aave avoided bad debt in its v3 market by using overcollateralization, automated liquidations and other strategies that shifted risk to borrowers.

In comments to Cointelegraph, Aave defended its liquidation-based model, framing it as a core safety mechanism that protects lenders while limiting downside for borrowers.

It comes as Aave parted ways with its longest-standing DeFi risk service provider, Chaos Labs, on April 6, following disagreements over the direction of Aave v4 and budget constraints.
