QCP Group released an article today Weighing the quantum risks of cryptocurrencies, yet Google whitepaper as of March 30 Bitcoin-style elliptic curve cryptography can be broken using far fewer quantum resources than previously assumed.

A bigger threat goes beyond cryptocurrencies
Cryptocurrency panic continues to spread, with multiple important voices from cryptocurrencies and technology, Like former Binance CEO Changpeng Zhao (CZ)and respond to the report in different ways.
The QCP article, written by Rachel Lee, defines the company’s view in a simple sentence: The quantum threat is more of an ongoing structural challenge than a short-term market threat.
At QCP, we view this as a long-term structural issue, rather than an immediate market risk. The distinction is important.
What it means to me is that the target of the threat is not cryptocurrencies in isolation: it’s the entire public key infrastructure stack that also secures banking rails like SWIFT, TLS/HTTPS, virtual private networks (VPNs) and the broader financial plumbing.
So a breakthrough in quantum computing that compromises ECC would have system-wide implications, not just digital assets.
This quantum vulnerability occurs because what quantum computers can actually break are public key signatures (ECDSA, Ed25519, RSA), not the proof-of-work consensus mechanism that makes blockchain technology considered so secure.
“A transition, not a departure,” QCP says.
Lee reminds us that we are “still a long way away” from the technological power needed to break the aforementioned ECDLP standard. As of today, our most advanced quantum systems operate about 1,000 times below the threshold needed to even carry out such an attack.
Importantly, the QCP argues that even in a scenario where we possess the computational power that would make any of this possible, digital assets would by no means be the primary target. TradFi and networks holding confidential or highly important information are more tempting targets.
The global banking system and sensitive communications infrastructure would provide more immediate and valuable attack surfaces.
Ironically, this means that cryptocurrencies are in a better position to coordinate controversial upgrades than many siled banking and government systems that rely on slow hardware update cycles and outdated HSMs.
The system is actually re-pricing this structurally. Both the cryptocurrency sector and traditional finance are already pouring resources into post-quantum defenses and migration plans. Protocol communities are testing mitigation approaches, even as global security standards continue to improve.
Efforts, such as post-quantum standards developed by Italy’s National Institute of Standards and Technology (NIST) and Google’s internal quantum deadline of 2029, are solidifying quantum risks from the status of science fiction to a real-life technological shift.

Immediate market effects
According to QCP, quantum is now a major background risk factor for cryptocurrencies, rather than a near-term catalyst. It’s more relevant to long-term value, L1 roadmaps, and portfolio design than next month’s price action.
Quantum computing is a long-term problem that the industry must monitor and prepare for, not a near-term reason to reevaluate digital assets.
Protocols and projects capable of shipping post-quantum signatures, aggressive key management, and private note pools may attract a “quantum-ready” premium over time, while assets with ossified governance or huge pools of exposed coins will trade at a structural discount.
