Will quantum computing destroy Bitcoin? Saylor: The crypto community will strike back first

The world’s largest Bitcoin institutional holder, MicroStrategy (MSTR), CEO Michael Saylor, recently publicly refuted the theory that quantum computing poses an imminent threat, stating that the cybersecurity community generally believes that credible quantum attack capabilities are still at least ten or more years away. He emphasized that once such a threat materializes, global digital infrastructure will upgrade collaboratively to respond, and the cryptocurrency community will play a leading role.

Saylor: Quantum Threats Are Overhyped

In the podcast Coin Stories, Saylor’s attitude toward quantum computing is surprisingly calm. He pointed out that all digital systems supporting modern society—including the global banking system, internet infrastructure, artificial intelligence networks, and various encryption protocols—will face the same quantum risks. Bitcoin is not a particularly vulnerable target but is one of many systems that require coordinated upgrades.

In his view, the transition to post-quantum cryptography is neither surprising nor will it happen suddenly. “You will see it coming, we will all see it coming,” Saylor said. He noted that Bitcoin’s software architecture is designed to evolve continuously over time, with nodes, hardware, and wallets all capable of upgrades to address emerging threats.

Why Does Bitcoin Have a Natural Advantage in Response?

Saylor presented three core points explaining that Bitcoin’s ability to respond to quantum computing threats is not inferior to traditional systems:

Stricter Security Standards: The verification processes required for Bitcoin transactions are far more rigorous than traditional bank wire transfers or stock trading systems, with multi-factor authentication and hardware keys being standard protections.

Fastest Community Response: The cryptocurrency field gathers the “most advanced cybersecurity communities,” which will be the quickest to perceive and respond if threats materialize.

Built-in Upgrade Mechanisms: The decentralized nature of global nodes allows Bitcoin to coordinate the deployment of post-quantum resistant cryptographic technologies when threats appear.

Industry Disagreement: Escalating Debate Over Threat Timeline

However, Saylor’s optimistic tone is not the consensus within the industry, and there are clear disagreements in the crypto community regarding the timeline of the quantum threat.

Ethereum founder Vitalik Buterin’s stance is much more urgent. He has publicly warned that the elliptic curve cryptography underpinning Ethereum and Bitcoin could face credible attacks by 2028, and called for the transition to post-quantum cryptography within four years. The Ethereum Foundation has incorporated post-quantum preparedness into its 2026 security roadmap and officially established a dedicated post-quantum research team this January, viewing it as a key strategic turning point.

Some even cite the quantum threat as an underlying reason for Bitcoin’s recent price decline. Bitcoin’s price has fallen from over $126,000 at its peak to around $64,000 now, a decline of over 49%. Nic Carter, partner at Castle Island Ventures, pointed out that Bitcoin’s “mysterious” poor performance can partly be attributed to market fears spreading over quantum risks.

In response, Glassnode analyst James Check remains cautious, believing that while quantum threats are worth preparing for in advance, they are not the “main reason” for this price drop. He suggests the market should not confuse short-term sentiment with long-term structural risks.

MicroStrategy Continues Buying: Action Is the Strongest Statement

For Saylor, the most convincing argument may not be words but actions. MicroStrategy announced last week that it purchased approximately $39.8 million worth of 592 Bitcoin, marking its 100th transaction since adopting a Bitcoin-focused strategy in August 2020. Currently, the company holds a total of 717,722 Bitcoin, with a market value of about $54.56 billion, and an average cost basis of $67,286 per Bitcoin.

Such continuous accumulation is itself a direct response to the quantum threat theory—in Saylor’s framework, quantum computing is far from posing a threat capable of shaking Bitcoin’s foundation in the foreseeable future.
