Only 10K Bitcoin is Quantum-Vulnerable and Worth Attacking

Bitcoin’s Quantum Threat: A $719 Million Risk That’s More Hype Than Reality, Says CoinShares

The world of cryptocurrency is no stranger to doomsday predictions, but the latest quantum computing scare has Bitcoin enthusiasts divided. While some see it as an existential threat to the $1.4 trillion network, one of the crypto industry’s leading asset managers is calling it a manageable risk—and the numbers back them up.

CoinShares, a prominent digital asset manager, has released a comprehensive analysis that should calm nerves across the Bitcoin community. Their research reveals that only a tiny fraction of Bitcoin—just 10,230 BTC out of 1.63 million—are actually vulnerable to quantum computing attacks.

To put that in perspective, that’s approximately $719 million at current market prices. While certainly not pocket change, CoinShares’ Bitcoin research lead Christopher Bendiksen argues this amount “could even resemble a routine trade” in today’s crypto markets.

The Real Numbers Behind the Quantum Fear

The vulnerability analysis breaks down the at-risk Bitcoin holdings by wallet size. About 7,000 BTC are held in wallets containing between 100 and 1,000 BTC, while roughly 3,230 BTC sit in larger wallets holding 1,000 to 10,000 BTC. The remaining 1.62 million Bitcoin, held in wallets with under 100 BTC each, would require a millennium to crack—even under “the most outlandishly optimistic scenario of technological progression in quantum computing.”

This isn’t just academic hand-waving. The research identifies these vulnerable coins as unspent transaction output (UTXO) wallets—essentially chunks of Bitcoin tied to wallet addresses that haven’t been moved. Many of these at-risk wallets date back to Bitcoin’s earliest days, the so-called “Satoshi era.”

The Science Behind the Scare

The quantum threat stems from two specific algorithms that could theoretically break Bitcoin’s security. Shor’s algorithm could compromise Bitcoin’s elliptic-curve signatures, while Grover’s algorithm might weaken the Secure Hash Algorithm 256-bit (SHA-256). However, Bendiksen emphasizes that neither algorithm could alter Bitcoin’s fundamental 21 million supply cap or bypass proof-of-work—the two pillars of Bitcoin’s value proposition.

A Community Divided

The quantum computing debate has split the Bitcoin community into two camps. On one side, influential figures like Strategy executive chairman Michael Saylor and Blockstream CEO Adam Back argue the threat is “overblown” and won’t disrupt the network for decades. They point to the current state of quantum computing technology as evidence.

Google’s latest quantum computer, Willow, has achieved 105 qubits—impressive, but still millions short of what would be needed for a real-world attack on Bitcoin. Bendiksen notes that “recent advancements, including demonstrations by Google and others, represent progress but fall short of the scale needed for real-world attacks on Bitcoin.”

On the other side of the debate are voices like Capriole Investments founder Charles Edwards, who views quantum computing as a potential “existential threat” to Bitcoin. Edwards argues that waiting is not an option and that an upgrade to strengthen network security should happen now.

The Fork in the Road

The community’s division centers on whether to implement a quantum-resistant hard fork or maintain the status quo. Some researchers, like Blockstream’s Jonas Nick, suggest that adopting post-quantum signatures could be the solution. Edwards even speculates that Bitcoin could be “repriced significantly higher” once such a solution is implemented, turning a potential vulnerability into a catalyst for growth.

Why This Matters Now

The timing of this debate is crucial. Bitcoin has weathered numerous storms—from regulatory crackdowns to market crashes—but a fundamental compromise of its cryptography would be unprecedented. The network currently secures $1.4 trillion in value, making any potential vulnerability a serious concern for investors and users alike.

Yet CoinShares’ analysis suggests the panic may be premature. By quantifying exactly how much Bitcoin is at risk and demonstrating the astronomical computing power required to compromise even those holdings, they’re providing a much-needed dose of reality to what could otherwise become another round of FUD (fear, uncertainty, and doubt) in the crypto markets.

The Bottom Line

While quantum computing represents a legitimate long-term challenge for Bitcoin, the immediate threat appears minimal. With only 0.6% of all Bitcoin potentially vulnerable, and those holdings requiring computing power that doesn’t yet exist, Bitcoin’s core security remains intact for now.

As Bendiksen concludes, Bitcoin is “nowhere near dangerous territory.” The network’s foundational features—its capped supply and proof-of-work consensus—remain secure against even the most advanced quantum algorithms currently imaginable.

For investors, developers, and users, this means Bitcoin can continue focusing on its primary mission: providing a decentralized, secure store of value in an increasingly digital world. The quantum threat, while real, is manageable—and perhaps even an opportunity for the network to evolve and strengthen its already robust security model.
