A new a16z crypto research paper argues that apocalyptic narratives about quantum computers instantly killing Bitcoin are badly misaligned with reality, and that the real risk for blockchains lies in long, messy migrations rather than a sudden “Q-Day” collapse. The piece has already triggered a sharp rebuttal on X from investors who say the threat is closer and harder than a16z suggests.

Bitcoin Isn’t Doomed By Quantum Computing: a16z

In the article “Quantum computing and blockchains: Matching urgency to actual threats,” a16z research partner and Georgetown computer science professor Justin Thaler sets the tone early, writing that “Timelines to a cryptographically relevant quantum computer are frequently overstated — leading to calls for urgent, wholesale transitions to post-quantum cryptography.” He argues that this hype distorts cost–benefit analyses and distracts teams from more immediate risks such as implementation bugs.

Thaler defines a “cryptographically relevant quantum computer” (CRQC) as a fully error-corrected machine capable of running Shor’s algorithm at a scale where it can break RSA-2048 or elliptic-curve schemes like secp256k1 in roughly a month of runtime. In his assessment, a CRQC in the 2020s is “highly unlikely,” and public milestones do not justify claims that such a system is probable before 2030.

He stresses that across trapped-ion, superconducting and neutral-atom platforms, no device is close to the hundreds of thousands to millions of physical qubits, with the required error rates and circuit depth, that would be needed for cryptanalysis.

Instead, the a16z piece draws a sharp line between encryption and signatures. Thaler argues that harvest-now-decrypt-later (HNDL) attacks already make post-quantum encryption urgent for data that must remain confidential for decades, which is why large providers are rolling out hybrid post-quantum key establishment in TLS and messaging.

But he insists that signatures, including those securing Bitcoin and Ethereum, face a different calculus: they do not protect hidden data that can be retroactively decrypted, and once a CRQC exists, the attacker can only forge signatures going forward.

On that basis, the paper claims that “most non-privacy chains” are not exposed to HNDL-style quantum risk at the protocol level, because their ledgers are already public; the relevant attack is forging signatures to steal funds, not decrypting on-chain data.

Bitcoin-Specific Headaches

Thaler still flags Bitcoin as having “special headaches” due to slow governance, limited throughput and large pools of exposed, potentially abandoned coins whose public keys are already on-chain, but he frames the time window for a serious attack in terms of at least a decade, not a few years.

“Bitcoin changes slowly. Any contentious issues could trigger a damaging hard fork if the community cannot agree on the appropriate solution,” Thaler writes, adding “another concern is that Bitcoin’s switch to post-quantum signatures cannot be a passive migration: Owners must actively migrate their coins.”

Moreover, Thalen flags a “final issue specific to Bitcoin” which is its low transaction throughput. “Even once migration plans are finalized, migrating all quantum-vulnerable funds to post-quantum-secure addresses would take months at Bitcoin’s current transaction rate,” Thaler says.

He is equally skeptical of rushing into post-quantum signature schemes at the base-layer. Hash-based signatures are conservative but extremely large, often several kilobytes, while lattice-based schemes such as NIST’s ML-DSA and Falcon are compact but complex and have already produced multiple side-channel and fault-injection vulnerabilities in real-world implementations. Thaler warns that blockchains risk weakening their security if they jump too early into immature post-quantum primitives under headline pressure.

Industry Split On The Risk

The most forceful pushback has come from Castle Island Ventures co-founder Nic Carter and Project 11 CEO Alex Pruden. Carter summed up his view on X by saying the a16z work “wildly underestimates the nature of the threat and overestimates the time we have to prepare,” pointing followers to a long thread from Pruden.

Pruden begins by stressing respect for Thaler and the a16z team, but adds, “I disagree with the argument that quantum computing is not an urgent problem for blockchains. The threat is closer, the progress faster, and the fix harder than how he’s framing it & than most people realize.”

He argues that recent technical results, not marketing, should anchor the discussion. Citing neutral-atom systems that now support more than 6,000 physical qubits, Pruden points out that “we now have a non annealing system with more than 6000 physical qubits in the neutral atom architecture,” directly contradicting any implication that only non-scalable annealing architectures have reached that scale. He notes that work such as Caltech’s 6,100-qubit tweezer array shows large, coherent, room-temperature neutral-atom platforms are already a reality.

On error correction, Pruden writes that “surface code error correction was experimentally demonstrated last year, moving it from a research problem into an engineering problem,” and points to rapid advances in color codes and LDPC codes.

He highlights Google’s updated “Tracking the Cost of Quantum Factoring” estimates, which show that a quantum computer with about one million noisy physical qubits running for roughly a week could, in principle, break RSA-2048 — a twenty-fold reduction from Google’s own 2019 estimate of twenty million qubits. “Resource estimates for a CRQC running Shor’s algorithm have dropped by two orders of magnitude in six months,” he notes, concluding, “To say that this trajectory of progress might potentially deliver a quantum computer before 2030 is not an overstatement.”

Where Thaler emphasizes HNDL as an encryption problem, Pruden reframes blockchains as uniquely attractive quantum targets. He stresses that “public keys used in digital signatures are just as easy to harvest as encrypted messages,” but in blockchains those keys are directly tied to visible value. He points out that “these public keys are distributed & directly associated with value ($150B for Satoshi’s BTC alone),” and that once a quantum adversary can forge signatures, “If you can forge a signature, you can steal the asset regardless of when that original UTXO/account was created.”

For Pruden, this economic reality means “the economic incentives simply and clearly point to blockchains as being the first cryptographically relevant quantum use case,” even if other sectors also face HNDL risks. He adds that “blockchains will be far slower to migrate than centralized systems. A bank can upgrade its stack. Blockchains must reach global consensus, absorb performance trade-offs from PQ signatures, and coordinate millions of users to migrate their keys.”

Invoking Ethereum’s multi-year shift from proof of work to proof of stake, he writes, “The closest thing was the ETH 1.0 to 2.0 transition which took years, and as complex as that was, a PQ migration is much harder. Anyone who thinks this is a matter of swapping a few lines of signature code has simply never shipped, deployed, or maintained a production blockchain.”

Pruden agrees with Thaler that panic is dangerous, but flips the conclusion: “I agree that rushing is dangerous. But that is exactly why work must begin now. The most likely failure mode is that the industry waits too long, and then a major QC milestone triggers a panic.” He closes by saying he disagrees that “quantum computing is progressing slowly,” that “blockchains are less vulnerable than systems exposed to HNDL risk,” or that “the industry has years of slack before action is needed,” arguing that “All three assumptions are at odds with reality.”

At press time, Bitcoin stood at $91,616.

The long-running question about whether another cryptocurrency can truly match what Bitcoin represents has resurfaced, and Ripple’s Chief Technology Officer David Schwartz has stepped forward to offer his opinion. 

His comments were based on an argument claiming that Bitcoin’s properties could be copied by simply recreating its code. This, in turn, was based on comments regarding a debate between Binance founder Changpeng Zhao and Bitcoin critic Peter Schiff.

Inside The Zhao-Schiff Debate On Bitcoin’s Value

During their discussion at the Binance Blockchain Week, Schiff stated that a token backed by gold is grounded in physical utility because the token merely represents ownership of a scarce commodity used by industries across the world. He contrasted this with Bitcoin, which he claimed derives its value from faith and has no practical use. 

Zhao countered by pointing out that even physical gold is difficult to divide or verify without additional processes, noting that he once received a gold bar as a gift but could not break it or confirm its purity without specialized tools. He contrasted this directly with Bitcoin, which can be transferred and verified instantly through the blockchain.

Again, Schiff responded by insisting that Bitcoin remains worthless to him because you can’t do anything with it, while gold carries intrinsic industrial demand. Zhao pushed back by highlighting that Bitcoin’s utility is tied to its transparent network, fixed supply, and verifiable ownership. He argued that unlike gold, whose total global reserves are uncertain, Bitcoin offers perfect clarity about supply and movement. 

The debate eventually escalated into a broader argument over value, with Schiff insisting Bitcoin has only speculative worth, while Zhao maintained that its network and transparency serve as the foundation for its trillion-dollar market capitalization.

“We’ll agree to disagree,” Zhao said.

Comment Raises Question: Can Bitcoin Be Replicated?

Following the debate, a viewer commented that Bitcoin’s uniqueness is overstated because someone could simply replicate it. The comment noted, “How long would it take to replicate Bitcoin? Create a new one, exactly the same. How much would it cost?”

It was this claim, rooted in Schiff’s argument that Bitcoin lacks intrinsic qualities, that led to David Schwartz entering the conversation.

Schwartz responded with a rhetorical question that cuts through the idea entirely. He asked how the new Bitcoin could be new and exactly the same as the original one. He continued, “And how would the existence of replicas of Bitcoin affect Bitcoin?” 

His point echoed Zhao’s argument about verifiability. A replica may copy Bitcoin’s code, but it cannot copy the network of users, miners, institutions, and real-time validation that give Bitcoin its identity. 

The existence of another chain does not dilute Bitcoin’s legitimacy any more than counterfeit gold reduces the value of real gold when proper verification exists. It also goes back to the comment by Changpeng Zhao that Bitcoin can be easily verified in multiple ways, unlike gold.

Старший аналитик Bloomberg Intelligence Эрик Балчунас (Eric Balchunas) заявил, что успех биткоина нельзя сравнивать со спекулятивным финансовым «тюльпановым пузырем», лопнувшем в Нидерландах в 1637 году.

The Bitcoin price continues its descent deep into red territory, as investors increasingly tread the capitulation path. Interestingly, a recent on-chain analysis has been carried out, which dives into the underlying factors that typically control Bitcoin’s December price action.

Coinbase Premium Suddenly Flips Into Negative Territory: Why This Is Important

In a QuickTake post on the CryptoQuant platform, crypto education institution XWIN Research Japan reported that the Coinbase Premium Index metric has recently seen a sharp nosedive. For context, this metric measures the price difference between Bitcoin on the Coinbase (USD) market and Bitcoin on other major global exchanges (such as Binance), or the USDT market. By doing so, it reflects the buying or selling biases of US investors and helps derive insights regarding their behavior.

According to the crypto research institute, the decline started around the late period of November, into early December. Because this decline correlates with an also sharp fall in the Bitcoin price, the apparent sentiment shift among investors from the US appears to be the source of the bearish pressure seen early in the month.

 

Interestingly, there are historical events that parallel the aforementioned scenario. Typically, December witnesses weaker readings from the Premium when compared to its performance throughout the year. The readings are often near or below zero “largely due to year-end rebalancing and tax-loss harvesting by US institutions and individuals,” XWIN Research highlights.

However, there have been slight deviations from this recurrent pattern. In 2018 and 2022, the Premium saw deep dives into negative zones, as the market was under significant stress in these periods. On another hand, 2020 and 2023 saw positive readings from the Premium, positively correlating with the ongoing bull-market momentum at the time.

‘December 2025 Appears To Be Unique’ — Research Group

XWIN Research Japan, however, made it worthy of note that this year’s scenario has its own “unique twist.” Notably, although the Coinbase Premium began in December with a negative, it has refused to maintain this state. Instead, the analytics platform reports that there was an almost immediate rebound not just into neutral levels, but back into positive territory. 

Because this sharp reversal took place within just a few days, it becomes apparent that the Bitcoin market may have seen the last strengths of extant bearish pressure. Interestingly, historical data reveal that such moves as the market has seen often precede price stabilization, or even short-term recoveries. Thus, if history is anything to go by, the Bitcoin price could be close to a local bottom, after which its recovery might follow.

Ultimately, XWIN Research points out that the stabilization, or sustained downturn, of the Bitcoin price depends mostly on “upcoming US capital flows, derivatives positioning, and premium trends.” At press time, Bitcoin holds a valuation of $89,321, with no significant movement since the past day.

The cryptocurrency market has had a year filled with ups and downs, with most large-cap digital assets turning in mixed performances in 2025. After a rough start to the year, things started to look up for the price of Bitcoin in the second and third quarters, as it set multiple all-time highs across the six-month period.

However, the flagship cryptocurrency has largely struggled in the final months of 2025, looking set to end the year in the red. Interestingly, the latest on-chain data and historical patterns suggest that the price of Bitcoin might be set for a fairly stronger yearly close than expected.

No Negative Days Left In 2025, But 2026 Could Feature A Deep Correction 

On Saturday, December 6, Alphractal CEO and founder Joao Wedson took to the X platform to share what to expect from the Bitcoin price in the last days of 2025. According to the on-chain expert, the market leader is likely to close the year in a sideways price range.

The relevant metric here is the Yearly Accumulated Negative Days, which tracks market resilience by measuring the number of days in a year where an asset’s daily price candlestick closed in the red. 

According to historical data and patterns, Bitcoin typically witnesses an average of 170 days of negative price movement in a year. This mean figure or level provides insight into the stress threshold for the world’s largest cryptocurrency by market cap. 

When the number of negative days is approaching or exceeds this threshold of 170 days, as Bitcoin already has in 2025, the selling pressure in the market tends to wane as fatigue sets in among the bears. Wedson revealed that the premier cryptocurrency has already accumulated 171 negative days so far in 2025.

The on-chain expert noted that exceeding this threshold “strongly suggests” that the price of Bitcoin might not witness any more negative days in the final few weeks of 2025. Wedson said that if a deeper correction is imminent for the market leader, it will most likely happen in the next year.

However, as the Alphractal founder highlighted, the Bitcoin price is more likely to end the year within a consolidation range. Adding further credence to this postulation is the lack of market demand, as seen with reduced capital influx into spot Bitcoin exchange-traded funds.

Bitcoin Price At A Glance

As of this writing, the price of BTC stands at around $89,397, reflecting a mere 0.3% drop in the past 24 hours. 

Председатель правления BitMine и сооснователь компании Fundstrat Том Ли (Tom Lee) заявил, что в ближайшие несколько месяцев у эфира есть шанс достигнуть $20 000.

American multinational financial services company Western Union has unveiled a stablecoin strategy to expand its digital business and cross-border remittances. In particular, the money transfer firm is looking to launch a stablecoin card service targeted at nations with high inflation rates.

Western Union Stablecoin Agenda

Matthew Cagwin, chief financial officer and executive vice-president at Western Union, has shared various ideas the financial service giant holds around the adoption and potential offerings of stablecoins. These revelations were made in a presentation at the UBS Global Technology and AI conference on December 2, 2025. 

Notably, Cagwin acknowledges that Western Union views stablecoins as a significant opportunity to free the company’s cash flow for other purposes. Due to the instantaneous and predictable nature of these cryptocurrencies, the executive outlines a business model in which Western Union can settle transactions immediately, without needing to hold hundreds of millions of dollars for liquidity, as is typical in the traditional financial system.

Notably, Western Union also aims to offer a “stable card”, modeled on the prepaid card in the US but targeted at users in nations with high inflationary pressure. Cagwin explained the need for this product, referencing Argentina as an example. 

The CFO said:

… If you’re — I have a big workforce in Argentina. Can you imagine living in a country where last year, your inflation was 250%, 300%. We gave our employees 4 raises last year because if you didn’t, they made — they couldn’t afford their bills. So imagine a world where your family in the U.S. is sending you $500 home, but by the time you spend it in the next month, it’s only worth $300. So we can see a good utility for our stable card there,…

Cagwin also explains Western Union’s ongoing efforts to establish a digital asset network (DAN). Notably, the financial services firm has established partnerships with four service providers with the intent to offer on-ramp and off-ramp services to users from H1 2026, using the yellow wallets and agents, such as a big box store or check casher.

Western Union Eyes Stablecoin Launch

In addition to the stable card, Cagwin states that Western Union plans to launch a stablecoin, which they believe will scale easily, considering their present business network. In opting against onboarding existing stablecoins, Cagwin explains the firm’s goal of maintaining end-to-end of the proposed coin’s use, economics, and distribution operation.

At press time, the total crypto market cap is valued at $3.05 trillion, after a 0.37% gain in the last day. Meanwhile, total stablecoins are valued at $317.63 billion, representing 10% of circulating digital assets.
