Is Quantum Proof Bitcoin Wallet Insurance or Fear Tax?

Cryptocurrency wallet makers and security companies are pushing post-quantum products despite the lack of large-scale quantum computers capable of crunching bitcoin.

The US National Institute of Standards and Technology (NIST) has finalized the first post-quantum cryptography standards by 2024 and calls for migration before 2030.

As standards bodies plan for a gradual transition to cryptographic graphics, parts of the wallet market are cashing in on that future.

“I feel that the fear tax is a little. We know that quantum computers are far away – they are still five to 15 years away,” Alexei Zamyatin, co-founder of Build on Bitcoin (BOB), told Cointelegraph.

Bitcoin is 50% below its October 2025 all-time high. Among the few theories trying to explain crypto's recent decline is the growing fear that quantum computing risks could deter institutional capital from Bitcoin.

Quantum risk is not zero, and it is not random.

An oft-discussed quantum vulnerability is Bitcoin's Elliptic Curve Digital Signature Algorithm, which authorizes transactions. In theory, a powerful quantum computer could extract the public key from an exposed private key and query the coins stored in the address.

Today's quantum hardware cannot break elliptic curve signatures. This does not mean that threat actors are waiting for a technical breakthrough.

“Many users expect a ‘Q-day' in the future when cryptography suddenly fails. In reality, the risk gradually accumulates as cryptographic assumptions weaken and vulnerability increases,” Kapil Diman, CEO and co-founder of Kuranium, told Cointelegraph.

“Now Harvest, decrypt-behind mechanisms are active, meaning data and signatures exposed today are being collected against future capabilities,” he said.

In Bitcoin's case, the concern is for old exposed public keys. Once a public key is visible in a chain, it remains visible permanently. Modern address formats obfuscate public keys until coins are issued.

According to CoinShares Bitcoin researcher Christopher Bendixen, 10,230 bitcoins (BTC) are sitting in addresses with publicly exposed public keys that would be vulnerable to a powerful enough quantum attack.

The business of quantum fear

As the Bitcoin community debates how far quantum computing is, crypto wallet makers are working on their own clock.

Trezor's Safe 7 is marketed as a “quantum-ready” hardware wallet. Separately, qLabs recently introduced a quantum-sig wallet that it says embeds post-quantum signatures directly into the signature process.

BOB's Zamyatin argued that wallet-level protection does not address Bitcoin's quantum risk. Bitcoin transactions are authorized using the signature scheme included in the protocol. If that cryptography is broken, the fix requires a protocol-level change.

“I personally don't invest a lot of money in a quantum wallet at the moment because I don't even know what protection it gives me for Bitcoin. In my opinion, it can't give me any protection because Bitcoin doesn't have a quantum-resistant signature scheme yet.”

Ada Jonušė, CEO of qLabs, agrees that full quantum resilience requires protocol-level protection. However, brushing off modern infrastructure as a fear tax addresses the transitional nature of security reforms.

“Quantum risk is not binary. Even before protocol-level migration occurs, there is a real ‘harvest now, decrypt later' risk,” she told Cointelegraph, adding that qLabs' approach would reduce the number of exposed keys.

“Quantum readiness is proactive infrastructure planning, not fear monetization,” Jonushe said.

Trezor also acknowledges that blockchains themselves need to change their encryption and protocol. But the company's chief technology officer, Tomasz Susanka, told Cointelegraph that wallets can implement protections immediately instead of waiting for extended blockchain updates.

“Once blockchain evolves, wallets will need to support the same algorithms to remain compatible,” Susanka said. He added that Trezor Safe 7 uses a post-quantum algorithm to prevent future quantum computers from creating digital signatures and signing malware updates.

Market incentives and the hurdle of Bitcoin management

Unlike iPhones, which are released almost every year, hardware wallets and other security products have a multi-year product life cycle. Introducing post-quantum features into a new product gives customers a reason to buy a new device, even if the risk is remote.

“Yes, parts of the crypto industry have incentives to increase quantum risk, but this incentive is driven by regulatory and institutional alignment, not just periodic sales,” said Dihiman, who owns the Kisafe wallet of Koranium.

“For most users, quantum-secure wallets today serve as long-term insurance. A responsible approach is to acknowledge the transition ahead, avoid fear-driven urgency, and choose systems designed to evolve without forcing sudden replacements.”

Several blockchains are advancing with post-quantum mechanisms, but Bitcoin has been relatively dubious. Some of the network's most influential voices have called risk a problem for the future.

Unlike Bitcoin, Ethereum has a widely recognized image leader. Co-founder Vitalik Buterin has advocated for post-quantum events, and the network is headed in that direction.

For Bitcoin, the issue is social consensus, coordination and willingness to act, Zamyatin.

“It's not like that. [Bitcoin has] Everyone follows someone. “It requires a broad social consensus, which is very difficult to achieve,” he said.

Wallet makers agree that full quantum security must come from the protocol. But they can act as insurance to help investors sleep better at night, even if the risk is years out, even if some argue they are a tax on fear.
