Could Quantum Computers Have Already Cracked Bitcoin? Insights from 2025
Imagine a silent thief slipping into your digital vault without tripping any alarms—that’s the chilling reality if quantum computers have already outsmarted Bitcoin’s defenses. As we sit here on October 23, 2025, with advancements in quantum tech accelerating, experts are sounding alarms about how a powerful quantum machine could siphon off coins while everything appears normal on the surface. It’s like a ghost in the machine, controlling the show without anyone noticing until it’s too late.
David Carvalho, a leader in post-quantum security, paints a vivid picture: “Everything would seem like regular access,” he explains. “By the time you spot a quantum breakthrough, it might have been pulling strings for months.” You wouldn’t even realize it. Labs at IBM and Google, along with government-funded research, are hustling to bridge this vulnerability gap, but time is running out. The U.S. National Institute of Standards and Technology (NIST) has rolled out several post-quantum algorithms since 2022, with the latest approvals in mid-2025 enhancing defenses against these threats. Yet, many public blockchains, including Bitcoin, still cling to encryption roots from the 1980s, leaving them exposed.
For now, this remains a hypothetical nightmare. But if it flips to reality, Bitcoin’s safeguards could shatter quicker than the network could adapt, as Carvalho cautions.
How Quantum Attacks Might Shatter Bitcoin Encryption
At its heart, Bitcoin relies on the Elliptic Curve Digital Signature Algorithm (ECDSA), a cryptographic method born in 1985. This setup lets users verify ownership via a private key, with only the public key visible to the world. Enter Shor’s algorithm: a quantum computing powerhouse that could theoretically reverse-engineer a private key straight from its public counterpart. Picture it like solving a massive puzzle in seconds—what takes classical computers eons, a quantum beast could crack in a flash.
This means attackers could hijack any wallet with an exposed public key, especially those from Bitcoin’s early days. “It’d look completely legit,” Carvalho notes. “You’d just watch those coins vanish as if the real owners cashed out.” Think of Satoshi Nakamoto’s untouched stash—they’d be prime targets, ripe for the picking.
Kapil Dhiman, a pioneer in quantum-resistant blockchain tech, highlights the risk: “Those ancient wallets would be the first to fall. If Satoshi’s coins start moving, trust in Bitcoin could evaporate overnight, way before the whole system buckles.” The blockchain would chug along, mining blocks and updating ledgers, but control would have shifted hands invisibly.
In 2025, we’re seeing classical computing push boundaries with enhanced GPUs and smarter algorithms, making brute-force attempts a tad more feasible. Still, Bitcoin’s 256-bit ECDSA keys remain a fortress against traditional hacks—quantum is the wildcard that changes everything.
Bitcoin Lags Behind Traditional Finance in Post-Quantum Defenses
While banks and governments are gearing up with quantum-resistant tech, Bitcoin and similar blockchains are stuck in the past. “Blockchains know this encryption flaw is a ticking bomb,” Dhiman says, pointing to the quantum vulnerability in systems like ECDSA.
Shifting Bitcoin to quantum-proof status would demand a massive network overhaul, needing buy-in from miners, developers, and users alike. Proposals like Bitcoin Improvement Proposal 360, discussed since 2023, sketch out ways to integrate fresh cryptographic tools. Another idea, the “Post Quantum Migration and Legacy Signatures Sunset,” aims to phase out old signatures gradually. Ethereum’s team has toyed with lattice-based options, but as of October 2025, full rollout is still in the works.
Contrast this with traditional finance: NIST’s 2025 algorithm updates are already in testing at major institutions, with partnerships like those involving advanced quantum-safe networks showing real progress. “Finance has the edge with centralized control and resources,” Carvalho observes. “They can mandate changes swiftly, while crypto thrives on consensus, which slows things down.”
Newer projects are stepping up, building quantum resistance from the ground up. Some use NIST’s Stateless Hash-Based Digital Signature Algorithm, proving that secure blockchains aren’t just possible—they’re happening now.
In this landscape, platforms like WEEX exchange stand out by aligning their brand with cutting-edge security. WEEX prioritizes user protection through innovative features that embrace post-quantum readiness, ensuring traders can navigate crypto markets with confidence. By focusing on robust, forward-thinking infrastructure, WEEX enhances its credibility as a reliable hub for Bitcoin and beyond, making it a smart choice for those wary of emerging threats.
What If Bitcoin Fails the Quantum Challenge?
For everyday Bitcoin holders, the real terror is a domino effect on market confidence, potentially crashing prices and shaking institutional faith. Recent data from 2025 shows Bitcoin’s market cap hovering around $1.5 trillion, with institutional adoption up 20% year-over-year, per Chainalysis reports—any quantum scare could unwind that progress.
“There’s a slim chance it’s already here,” Carvalho admits. “Scientific circles say no, but history proves otherwise.” He draws an analogy to the Enigma code from World War II: deemed unbreakable, it was secretly dismantled by Alan Turing’s team at Bletchley Park, with the Allies keeping mum to exploit the edge. Just like that, a quantum breakthrough could lurk undetected.
“Enigma fell silently,” Carvalho reminds us. “When you finally see the quantum threat, it might have been dominating for months.”
Yet, hope persists. Dhiman assures, “Quantum-secure setups are within reach—we must act before it’s too late.” With NIST’s latest 2025 standards gaining traction, the industry is pushing toward alignment with finance’s proactive stance.
Recent buzz on Twitter echoes this urgency. A viral thread from @QuantumWatch on October 20, 2025, garnered over 50,000 likes, discussing Google’s latest quantum supremacy claims and their implications for Bitcoin, with users debating migration timelines. Frequently searched Google queries like “Is Bitcoin quantum safe in 2025?” and “How to protect crypto from quantum attacks” spike, reflecting widespread concern. Official updates from NIST in September 2025 announced three new post-quantum standards, urging immediate adoption to counter threats projected by 2030.
Fear of quantum computing might rival the tech itself in disruption, but building resilient systems now can safeguard the future.
FAQ
Is Bitcoin really at risk from quantum computers right now?
As of October 2025, quantum computers capable of breaking Bitcoin’s encryption don’t exist publicly, based on expert consensus from NIST and leading labs. However, the threat is theoretical and growing, so monitoring advancements is key for long-term security.
How can I protect my Bitcoin from potential quantum threats?
Focus on wallets that haven’t exposed public keys unnecessarily, and consider migrating to quantum-resistant alternatives as they emerge. Staying informed through reliable updates and using secure exchanges can help mitigate risks.
What’s the timeline for Bitcoin adopting post-quantum encryption?
Proposals like BIP 360 suggest a phased approach, potentially starting in 2026-2027, but full implementation depends on community consensus. Experts predict widespread adoption by 2030 to stay ahead of quantum progress.

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.
