Could Bitcoin Fall Below $50K by 2028 Due to Quantum Computing Risks?
Advances in quantum computing have prompted renewed scrutiny of Bitcoin’s cryptographic security, raising questions about whether the network could face significant vulnerabilities by 2028. While current quantum technology remains far from threatening Bitcoin’s encryption, experts warn that a breakthrough in quantum hardware could undermine Bitcoin’s foundational security model and potentially affect its market value.
What happened
Bitcoin’s security infrastructure primarily depends on the Elliptic Curve Digital Signature Algorithm (ECDSA) and the SHA-256 hashing algorithm. These cryptographic protocols are currently robust against attacks by classical computers but are theoretically vulnerable to quantum computers equipped with sufficient qubits and error correction, particularly through Shor’s algorithm. Research indicates that quantum computers would need approximately 4,000 error-corrected logical qubits to break Bitcoin’s ECDSA signatures within a timeframe relevant to transaction security.
As of early 2024, the most advanced quantum machines developed by leading organizations such as IBM Quantum and Google Quantum AI have achieved around 100 to 300 noisy qubits. This performance is significantly below the threshold required to compromise Bitcoin’s cryptography. Despite this, the quantum computing community continues to make steady progress, and the possibility of reaching the necessary scale by 2028 remains under discussion among experts.
The Bitcoin protocol currently lacks integrated quantum-resistant cryptographic algorithms. However, proposals for post-quantum signature schemes, including lattice-based cryptography, exist and are topics of ongoing academic and developer discourse within the Bitcoin Core community. Implementing such upgrades would require broad consensus and coordinated network changes, processes historically known to be complex and time-consuming.
Institutional investors and Bitcoin exchange-traded fund (ETF) issuers have expressed cautious awareness of quantum computing risks. Nonetheless, as of 2024, no formal regulatory filings or disclosures mandate specific risk mitigation strategies related to quantum threats. Market analysts and crypto security experts interviewed by Cointelegraph and independent outlets acknowledge the theoretical possibility of a quantum breakthrough by 2028 but emphasize that it is not guaranteed.
Why this matters
Bitcoin’s cryptographic security underpins the integrity and trust of its decentralized network. Should a quantum computer capable of breaking ECDSA signatures emerge, it could potentially allow attackers to forge transactions or steal funds, undermining user confidence and the network’s reliability. This theoretical vulnerability raises concerns about the long-term resilience of Bitcoin as a store of value and transactional medium.
From a market perspective, the emergence of credible quantum threats without timely mitigation could lead to a loss of confidence among investors and users, possibly depressing Bitcoin’s price below critical thresholds such as $50,000. The absence of quantum-resistant upgrades or regulatory guidance on quantum risk disclosures could exacerbate uncertainty and volatility in crypto markets.
Moreover, the challenge of implementing post-quantum cryptography in Bitcoin involves not only technical hurdles but also governance and coordination risks. Network upgrades require consensus among diverse stakeholders, and delays or disagreements could leave the network exposed during a critical period. This dynamic underscores the importance of proactive measures to safeguard Bitcoin’s security model.
What remains unclear
Despite ongoing research and discussion, several key questions remain unanswered. It is uncertain whether quantum hardware will attain the necessary scale and error correction capabilities by 2028 to pose a practical threat to Bitcoin’s cryptography. The timeline for integrating post-quantum cryptographic algorithms into Bitcoin’s protocol is also unclear, as is the likelihood that the Bitcoin community will reach timely consensus on such significant upgrades.
Additionally, there is limited public information regarding how institutional investors and ETF issuers are preparing to manage quantum computing risks within their disclosures and portfolio strategies. Without mandated regulatory requirements, the extent of market preparedness remains opaque. Finally, the potential market impact of widespread quantum threat awareness—absent concrete mitigation—has yet to be empirically assessed, leaving the question of price dynamics speculative.
What to watch next
- Progress in quantum computing hardware development, particularly milestones toward achieving thousands of error-corrected logical qubits.
- Advancements and proposals within the Bitcoin developer community regarding the adoption of post-quantum cryptographic algorithms.
- Regulatory initiatives or guidance addressing quantum computing risks and disclosure requirements for crypto assets and investment products.
- Statements, filings, or risk management updates from institutional investors and ETF issuers related to quantum threat preparedness.
- Research and analysis on market sentiment and price movements in response to emerging quantum risk narratives.
The question of whether Bitcoin could fall below $50,000 by 2028 due to quantum computing risks remains open and contingent on technological and governance developments. While the threat is theoretical at present, the evolving landscape calls for continued vigilance, coordinated technological innovation, and transparent market communication to address potential systemic vulnerabilities.
