What If Quantum Computers Have Already Cracked Bitcoin’s Security?
Imagine waking up one day to find your Bitcoin holdings vanishing into thin air, not through some dramatic hack, but quietly, as if you yourself decided to move them. That’s the chilling scenario experts warn about if quantum computers secretly break through Bitcoin’s defenses. A machine powerful enough to shatter current encryption could siphon off coins while the network hums along normally, leaving everyone none the wiser. As we sit here in 2025, with quantum tech advancing rapidly, this isn’t just science fiction—it’s a ticking time bomb that could upend the crypto world.
David Carvalho, a leader in post-quantum infrastructure, paints a stark picture: “Everything would appear as valid access,” he explains. “By the time you spot a quantum threat, it might have been lurking for months.” You wouldn’t notice a thing. Labs at giants like IBM and Google, along with government-funded efforts, are hustling to bridge this vulnerability gap. The U.S. National Institute of Standards and Technology (NIST) has rolled out several post-quantum algorithms since 2024, yet many blockchains still cling to outdated 1980s encryption. For now, it’s hypothetical, but if it turns real, Bitcoin’s shields could collapse quicker than the community could rally.
How Quantum Attacks Could Shatter Bitcoin Encryption
At Bitcoin’s heart lies the Elliptic Curve Digital Signature Algorithm (ECDSA), a cryptographic backbone dating back to 1985. It lets you prove wallet ownership via a private key, while only the public key shows up on the blockchain. Enter Shor’s algorithm: a quantum computing method that could, in theory, reverse-engineer that private key from the public one on a sufficiently advanced machine. Suddenly, any exposed public key—think early Bitcoin transactions—becomes fair game for thieves.
“It’d be undetectable because it mimics legitimate entry,” Carvalho notes. You’d just see funds shifting as if the owners chose to spend them. Kapil Dhiman, behind a quantum-focused blockchain initiative, highlights the prime targets: “Those ancient wallets, like Satoshi’s untouched stash, would be easy pickings.” If they stir, trust in Bitcoin could evaporate overnight, even as the chain keeps chugging. Blocks mine on, the ledger stays whole, but control slips away silently.
Contrast this with today’s reality: enhanced GPUs and smarter algorithms nudge brute-force attacks forward, but Bitcoin’s 256-bit ECDSA keys remain out of classical computers’ grasp. Still, as of October 2025, quantum milestones like Google’s recent claim of quantum supremacy in error-corrected systems (announced in a September 2025 paper) amp up the urgency. It’s like comparing a locked safe to a glass door—quantum tech could smash right through.
Bitcoin Lags Behind Traditional Finance in Post-Quantum Defenses
While banks and governments gear up for the quantum era, Bitcoin and its peers drag their feet on 1980s tech. “Blockchains know this encryption flaw is a core weakness,” Dhiman says, pointing to quantum computers’ potential to dismantle ECDSA. Upgrading Bitcoin demands a network-wide consensus revamp, involving miners, devs, and users— no small feat.
Proposals like Bitcoin Improvement Proposal 360 sketch paths to quantum-resistant crypto, and ideas for sunsetting old signatures are floating around. Ethereum folks have toyed with lattice-based options, but implementation lags. Meanwhile, traditional finance surges ahead: NIST’s 2024 approvals expanded in 2025 with fresh standards like ML-KEM and SLH-DSA, per their October 2025 update. Even players like JPMorgan have piloted quantum-safe ledgers.
“TradFi has the edge with centralized control and resources for swift changes,” Carvalho observes. “Crypto’s decentralized nature means consensus slows everything.” Newer chains are stepping up, baking in NIST-approved hash-based signatures from the start, proving quantum-secure systems aren’t just possible—they’re here.
In this evolving landscape, platforms like WEEX exchange stand out by prioritizing cutting-edge security that aligns with post-quantum standards, ensuring users trade Bitcoin and other assets with confidence. WEEX’s commitment to robust, forward-thinking infrastructure not only protects against emerging threats but also builds trust through seamless, user-focused features that make crypto accessible and secure for everyone.
The Fallout If Bitcoin Fails the Quantum Challenge
For everyday holders, the real nightmare is a confidence crash, tanking prices and shaking markets amid rising institutional crypto adoption. “There’s a slim chance it’s already happening,” Carvalho cautions, citing scientific consensus that it’s unlikely—but not impossible. He draws a parallel to the Enigma code in World War II: deemed unbreakable, yet secretly cracked by Alan Turing’s team, who kept it hush to exploit the edge.
“When a quantum system emerges publicly, it might have dominated quietly for months,” he warns. Yet hope persists: “Quantum-secure blockchains are within reach,” Dhiman affirms. “We must build them now.” As of October 2025, Twitter buzzes with discussions—posts from crypto influencers like @CryptoWhale alert over 500K followers to NIST’s latest approvals, sparking threads on quantum risks. Google searches spike for “quantum threat to Bitcoin 2025,” with users questioning timelines, often linking to official announcements like IBM’s Q3 2025 quantum roadmap revealing scalable qubit advances. Recent updates, including a U.S. government advisory on October 15, 2025, urge accelerated post-quantum migrations, fueling debates on forums about Bitcoin’s vulnerability window shrinking to 2030 or sooner.
Experts compare it to upgrading from an old lock to a biometric vault: delay too long, and you’re exposed. Real-world evidence? The 2025 quantum simulation attacks on scaled-down ECDSA keys by researchers at MIT, proving Shor’s algorithm works in practice, underscore the need for action. It’s not speculation—data from these breakthroughs shows the threat is closing in, pushing the industry toward resilient designs that safeguard your investments.
FAQ
What is the biggest quantum threat to Bitcoin right now?
The main risk comes from Shor’s algorithm potentially cracking ECDSA encryption, allowing attackers to steal private keys from public ones. As of 2025, no quantum computer can do this at scale, but progress in qubit stability makes it a growing concern.
How can I protect my Bitcoin from quantum attacks?
Move funds to wallets with unexposed public keys and stay updated on network upgrades. Consider platforms integrating post-quantum tech for added security, and diversify into quantum-resistant assets to mitigate risks.
When will quantum computers actually break Bitcoin?
Experts estimate 2030-2035 based on current trends, like Google’s 2025 quantum advancements. However, timelines vary; ongoing NIST standards and blockchain proposals aim to fortify defenses before then.

Debunking the AI Doomsday Myth: Why Establishment Inertia and the Software Wasteland Will Save Us
Editor's Note: Citrini7's cyberpunk-themed AI doomsday prophecy has sparked widespread discussion across the internet. However, this article presents a more pragmatic counter perspective. If Citrini envisions a digital tsunami instantly engulfing civilization, this author sees the resilient resistance of the human bureaucratic system, the profoundly flawed existing software ecosystem, and the long-overlooked cornerstone of heavy industry. This is a frontal clash between Silicon Valley fantasy and the iron law of reality, reminding us that the singularity may come, but it will never happen overnight.
The following is the original content:
Renowned market commentator Citrini7 recently published a captivating and widely circulated AI doomsday novel. While he acknowledges that the probability of some scenes occurring is extremely low, as someone who has witnessed multiple economic collapse prophecies, I want to challenge his views and present a more deterministic and optimistic future.
In 2007, people thought that against the backdrop of "peak oil," the United States' geopolitical status had come to an end; in 2008, they believed the dollar system was on the brink of collapse; in 2014, everyone thought AMD and NVIDIA were done for. Then ChatGPT emerged, and people thought Google was toast... Yet every time, existing institutions with deep-rooted inertia have proven to be far more resilient than onlookers imagined.
When Citrini talks about the fear of institutional turnover and rapid workforce displacement, he writes, "Even in fields we think rely on interpersonal relationships, cracks are showing. Take the real estate industry, where buyers have tolerated 5%-6% commissions for decades due to the information asymmetry between brokers and consumers..."
Seeing this, I couldn't help but chuckle. People have been proclaiming the "death of real estate agents" for 20 years now! This hardly requires any superintelligence; with Zillow, Redfin, or Opendoor, it's enough. But this example precisely proves the opposite of Citrini's view: although this workforce has long been deemed obsolete in the eyes of most, due to market inertia and regulatory capture, real estate agents' vitality is more tenacious than anyone's expectations a decade ago.
A few months ago, I just bought a house. The transaction process mandated that we hire a real estate agent, with lofty justifications. My buyer's agent made about $50,000 in this transaction, while his actual work — filling out forms and coordinating between multiple parties — amounted to no more than 10 hours, something I could have easily handled myself. The market will eventually move towards efficiency, providing fair pricing for labor, but this will be a long process.
I deeply understand the ways of inertia and change management: I once founded and sold a company whose core business was driving insurance brokerages from "manual service" to "software-driven." The iron rule I learned is: human societies in the real world are extremely complex, and things always take longer than you imagine — even when you account for this rule. This doesn't mean that the world won't undergo drastic changes, but rather that change will be more gradual, allowing us time to respond and adapt.
Recently, the software sector has seen a downturn as investors worry about the lack of moats in the backend systems of companies like Monday, Salesforce, Asana, making them easily replicable. Citrini and others believe that AI programming heralds the end of SaaS companies: one, products become homogenized, with zero profits, and two, jobs disappear.
But everyone overlooks one thing: the current state of these software products is simply terrible.
I'm qualified to say this because I've spent hundreds of thousands of dollars on Salesforce and Monday. Indeed, AI can enable competitors to replicate these products, but more importantly, AI can enable competitors to build better products. Stock price declines are not surprising: an industry relying on long-term lock-ins, lacking competitiveness, and filled with low-quality legacy incumbents is finally facing competition again.
From a broader perspective, almost all existing software is garbage, which is an undeniable fact. Every tool I've paid for is riddled with bugs; some software is so bad that I can't even pay for it (I've been unable to use Citibank's online transfer for the past three years); most web apps can't even get mobile and desktop responsiveness right; not a single product can fully deliver what you want. Silicon Valley darlings like Stripe and Linear only garner massive followings because they are not as disgustingly unusable as their competitors. If you ask a seasoned engineer, "Show me a truly perfect piece of software," all you'll get is prolonged silence and blank stares.
Here lies a profound truth: even as we approach a "software singularity," the human demand for software labor is nearly infinite. It's well known that the final few percentage points of perfection often require the most work. By this standard, almost every software product has at least a 100x improvement in complexity and features before reaching demand saturation.
I believe that most commentators who claim that the software industry is on the brink of extinction lack an intuitive understanding of software development. The software industry has been around for 50 years, and despite tremendous progress, it is always in a state of "not enough." As a programmer in 2020, my productivity matches that of hundreds of people in 1970, which is incredibly impressive leverage. However, there is still significant room for improvement. People underestimate the "Jevons Paradox": Efficiency improvements often lead to explosive growth in overall demand.
This does not mean that software engineering is an invincible job, but the industry's ability to absorb labor and its inertia far exceed imagination. The saturation process will be very slow, giving us enough time to adapt.
Of course, labor reallocation is inevitable, such as in the driving sector. As Citrini pointed out, many white-collar jobs will experience disruptions. For positions like real estate brokers that have long lost tangible value and rely solely on momentum for income, AI may be the final straw.
But our lifesaver lies in the fact that the United States has almost infinite potential and demand for reindustrialization. You may have heard of "reshoring," but it goes far beyond that. We have essentially lost the ability to manufacture the core building blocks of modern life: batteries, motors, small-scale semiconductors—the entire electricity supply chain is almost entirely dependent on overseas sources. What if there is a military conflict? What's even worse, did you know that China produces 90% of the world's synthetic ammonia? Once the supply is cut off, we can't even produce fertilizer and will face famine.
As long as you look to the physical world, you will find endless job opportunities that will benefit the country, create employment, and build essential infrastructure, all of which can receive bipartisan political support.
We have seen the economic and political winds shifting in this direction—discussions on reshoring, deep tech, and "American vitality." My prediction is that when AI impacts the white-collar sector, the path of least political resistance will be to fund large-scale reindustrialization, absorbing labor through a "giant employment project." Fortunately, the physical world does not have a "singularity"; it is constrained by friction.
We will rebuild bridges and roads. People will find that seeing tangible labor results is more fulfilling than spinning in the digital abstract world. The Salesforce senior product manager who lost a $180,000 salary may find a new job at the "California Seawater Desalination Plant" to end the 25-year drought. These facilities not only need to be built but also pursued with excellence and require long-term maintenance. As long as we are willing, the "Jevons Paradox" also applies to the physical world.
The goal of large-scale industrial engineering is abundance. The United States will once again achieve self-sufficiency, enabling large-scale, low-cost production. Moving beyond material scarcity is crucial: in the long run, if we do indeed lose a significant portion of white-collar jobs to AI, we must be able to maintain a high quality of life for the public. And as AI drives profit margins to zero, consumer goods will become extremely affordable, automatically fulfilling this objective.
My view is that different sectors of the economy will "take off" at different speeds, and the transformation in almost all areas will be slower than Citrini anticipates. To be clear, I am extremely bullish on AI and foresee a day when my own labor will be obsolete. But this will take time, and time gives us the opportunity to devise sound strategies.
At this point, preventing the kind of market collapse Citrini imagines is actually not difficult. The U.S. government's performance during the pandemic has demonstrated its proactive and decisive crisis response. If necessary, massive stimulus policies will quickly intervene. Although I am somewhat displeased by its inefficiency, that is not the focus. The focus is on safeguarding material prosperity in people's lives—a universal well-being that gives legitimacy to a nation and upholds the social contract, rather than stubbornly adhering to past accounting metrics or economic dogma.
If we can maintain sharpness and responsiveness in this slow but sure technological transformation, we will eventually emerge unscathed.
