“Should We Be Worried?” - What Quantum Really Means for Bitcoin
We received a brief but concerned email this week.
“Hey - seeing a lot about quantum computing potentially breaking Bitcoin. Is this something we should be worried about?”
It’s a simple question - but one that’s coming up with increasing urgency.
Attached in that email was a newly published report from Google outlining how advances in quantum computing could reduce the resources needed to break the cryptography that secures Bitcoin - along with a proposed timeline that brings the conversation closer to the end of the decade. Fortunately, we weren’t blindsided by the question - our research team has been closely following the issue - but we were surprised by the level of interest it’s suddenly generating.
That interest is understandable - but it’s also where things start to get distorted.
Headlines around quantum computing and Bitcoin tend to collapse a complex, long-term risk into something that sounds immediate and binary: either the system is secure, or it’s about to break. We argue the reality is far more nuanced - and still developing.
At a high level, the concern stems from a specific part of Bitcoin’s security model. While most people associate Bitcoin’s strength with its mining process, the area being discussed here is different - it’s the cryptography that protects wallet ownership and enables transactions. More specifically, the conversation centers around two core components: SHA-256 and elliptic curve cryptography (often referred to as ECDLP-256).
SHA-256 is the hashing function that underpins Bitcoin’s mining process and the integrity of the blockchain itself. It takes input data and converts it into a fixed digital fingerprint, making it extremely difficult to alter past transactions or manipulate the network. Elliptic curve cryptography, on the other hand, is what secures private keys and enables digital signatures - essentially proving ownership. When Bitcoin is sent from one wallet to another, this is the system that verifies the sender has the right to move those funds.
Understanding this is key - and it’s exactly the level of clarity more technical clients are looking for when they raise this question, because quantum computing doesn’t impact both areas in the same way.
The concern raised in the Google report centers specifically on elliptic curve cryptography - the system that secures private keys and underpins digital ownership within Bitcoin. In their findings, they note that future quantum computers may be able to break this form of encryption “with fewer qubits and gates than previously realized,” effectively lowering the computational threshold required to execute such an attack. In other words, the breakthrough isn’t that quantum computers can suddenly break Bitcoin today, but that the path to doing so may be shorter and more achievable than previously thought.
In practical terms, this doesn’t mean Bitcoin stops functioning or that the network itself fails. It means that, at a certain level of technological maturity, quantum systems could begin to target exposed public keys and derive their corresponding private keys - potentially allowing funds to be moved without authorization in specific cases. That risk is highly dependent on timing, implementation, and how the ecosystem responds, but it’s fundamentally different from the more dramatic scenarios often implied in headlines.
Our interpretation is not that this represents an instantaneous failure of the system, but the possibility of a gradual erosion in one part of Bitcoin’s security model - one that ultimately comes down to how quickly the technology develops relative to how quickly the network can adapt.
Interestingly enough, this isn’t a new conversation. Bitcoin’s creator, Satoshi Nakamoto, addressed this exact scenario more than a decade ago in a discussion on the early BitcoinTalk forum, making a distinction that feels especially relevant today.

“However, if something happened and the signatures were compromised (perhaps integer factorization is solved, quantum computers?), then even agreeing upon the last valid block would be worthless.”
Quote from Satoshi Nakamoto on July 10, 13:16:17 UTC
“True, if it happened suddenly. If it happens gradually, we can still transition to something stronger. When you run the upgraded software for the first time, it would re-sign all your money with the new stronger signature algorithm (by creating a transaction sending the money to yourself with the stronger sig).”
As fascinating as it is that this risk was being discussed that early, it’s how Satoshi handled it. He didn’t brush it off, but he also didn’t treat it like a fatal flaw. It reads more like someone calmly walking through a worst-case scenario and explaining what would actually happen.
His answer really comes down to timing. If something like this broke overnight, with no warning, that’s a serious problem. But if it develops over time - which is how most technological shifts tend to play out - there’s room to adjust. The network can upgrade, new cryptographic standards can be introduced, and users can move their funds into safer formats as those changes roll out.
It’s a practical way of thinking about it, and it reframes the issue entirely. The real question isn’t just whether quantum computing can break Bitcoin - it’s whether it can do so faster than the system can respond.
That way of thinking - where outcomes depend on how quickly a network can adapt - is already shaping how people are looking at different parts of the crypto market.
Some industry voices have pointed out that networks like Ethereum may be further along in thinking about post-quantum security, with more active research and discussion around transitioning to quantum-resistant cryptographic standards. Whether that ultimately proves to be a meaningful advantage remains to be seen, but it highlights an important dynamic: this isn’t a uniform risk across all assets. Different networks are approaching it with different levels of urgency, coordination, and technical flexibility.
At the same time, this framework leads to a much broader implication. If this ultimately becomes an industry-wide transition, it won’t just test Bitcoin - it will test everything. Protocols that are actively maintained, well-funded, and capable of coordinating upgrades are far more likely to adapt, while those that are underfunded, loosely maintained, and poorly coordinated will likely fall behind - and in many cases, disappear.
Some of the questions and concerns we’ve addressed this past week center around the idea of an industry “cleanse,” in the sense that if a transition to quantum-resistant cryptography becomes necessary, not every network will be able to keep up. This wouldn’t be a seamless upgrade - it would require coordination, active development, and users willing to migrate to new standards across tens of millions of tokens and projects. Many simply won’t have anyone show up, and even for those that do, the bar will be high - one that a large portion of the ecosystem isn’t built to meet.
With all of this in mind, we strongly encourage investors to begin paying closer attention to how different networks are approaching this problem - and, more importantly, how prepared they are to adapt if and when it becomes necessary.
Plus, not everyone sees this as purely a risk. Justin Drake, a researcher at the Ethereum Foundation who has contributed to post-quantum research and co-authored the Google paper, has framed this moment as an opportunity rather than a threat - one that could push the industry toward stronger foundations.
“I’ve stopped thinking about post-quantum as a hurdle that we have to overcome, and more as an opportunity… a chance to start with a clean slate and wipe out technical debt.”
We agree - quantum is an opportunity, one worth thoughtful consideration, not immediate concern, but one that will ultimately reveal which systems are built to adapt and which are not. Wall Street wouldn’t be diving headfirst into an asset class about to turn belly up - we are optimistic the challenge will be solved.
Coinbase Secures Federal Trust Charter, Signaling Deeper Integration With Traditional Finance
Coinbase received conditional approval from the Office of the Comptroller of the Currency to form a national trust company, giving it a unified federal framework for its custody and market infrastructure business. The company made clear this is not a move into traditional banking - it will not take retail deposits or engage in lending - but rather a way to operate under consistent oversight while expanding institutional services tied to safeguarding and moving digital assets.
What this really shows is where things are heading. Crypto firms are increasingly being pulled into the same regulatory architecture that underpins traditional finance, not by changing what they are, but by formalizing how they operate. A federal charter streamlines oversight, reduces reliance on a patchwork of state rules, and creates a clearer foundation for building products around custody, settlement, and payments. As policy efforts like the Clarity Act continue to evolve, moves like this show the direction of travel - toward integration, standardization, and a system that looks a lot more familiar to traditional markets.
Trump Reaffirms Pro-Crypto Stance, But Offers Few New Details
At the Future Investment Initiative, Donald Trump reiterated his stance on crypto, emphasizing U.S. leadership and framing it as a competitive race with China. He pointed to prior policy efforts like the Genius Act and reinforced a preference for minimal regulation and open market participation.
“My administration has also worked tirelessly to ensure that America remains at the bleeding edge of crypto revolution… if we’re not going to do it, then China is going to take it over. We’re going to be the undisputed crypto capital and Bitcoin superpower of the world… Bitcoin’s very powerful… so many people now want to pay you in crypto… Last year I signed the landmark Genius Act into law creating a clear and simple framework for dollar-backed stable coins… we don’t want any pointless regulations or needless restrictions… we want free enterprise.”
The remarks were largely consistent with prior messaging - broad support for crypto and U.S. leadership, but light on specifics. There was no mention of earlier proposals like a strategic Bitcoin reserve, nor of ongoing legislative efforts such as the Clarity Act. The takeaway is that crypto remains part of the narrative, but more as a positioning tool than a clearly defined policy priority at this stage.
Franklin Templeton Goes All-In On Crypto
Franklin Templeton is doubling down on digital assets, announcing plans to acquire crypto investment firm 250 Digital and launch a new division, Franklin Crypto. The deal brings over the team and liquid strategies previously run at CoinFund, with Christopher Perkins and Seth Ginns set to lead alongside Franklin veteran Tony Pecore. With its existing digital asset arm already managing around $1.8 billion, the move signals a clear shift toward building a more robust, institutional-grade platform designed to compete for capital in a rapidly maturing market.
The structure of the deal is just as notable as the strategy. Part of the acquisition will be paid using BENJI tokens - shares in Franklin’s on-chain U.S. Government Money Fund - marking one of the first real uses of tokenized assets in an M&A transaction. It’s a subtle but important shift: instead of limiting crypto exposure to ETFs, firms like Franklin are now building active strategies, dedicated teams, and on-chain financial infrastructure, reinforcing the idea that digital assets are becoming a permanent part of the institutional investment landscape.
Crypto Tax Reporting Enters A New Era - And It’s Catching Investors Off Guard
The 2026 crypto tax season is introducing a level of complexity that even seasoned investors aren’t fully prepared for. According to the 2026 Crypto Tax Readiness Report, a survey of 3,000 U.S. crypto users found that while most intend to comply with tax law, they face “profound confusion” around cost basis, taxable events, and evolving IRS rules. This isn’t surprising. Crypto portfolios often involve frequent transactions, asset swaps, and movement across multiple platforms - creating a level of recordkeeping complexity that traditional brokerage accounts simply don’t have.
What’s changed this year is visibility. For the first time, major platforms like Coinbase and others are required to report user activity directly to the IRS through Form 1099-DA - effectively crypto’s version of the 1099-B. However, the form reports gross proceeds without consistently including cost basis, meaning the IRS can see what was sold, but not necessarily what was paid. In cases where records are incomplete, the missing cost basis can default to zero, significantly overstating gains on paper.
The scope of reporting is also broader than many expect. Taxable events still include selling crypto for fiat and swapping between assets, while transfers between wallets or accounts are not taxable - though they complicate tracking. The challenge is that even small transactions, conversions, and stablecoin activity may now be captured in reporting, increasing the likelihood of discrepancies between what investors believe they owe and what is reflected in reported data.
The key issue is not just compliance - it’s accuracy. Investors are now responsible for reconciling cost basis across potentially years of fragmented activity. Leaving missing data unresolved can lead to overpaying taxes, while inaccurate estimates can create additional risk. The practical takeaway is straightforward: consistent recordkeeping, limiting platform sprawl, and making a reasonable, defensible effort to reconstruct transaction history are becoming essential as crypto reporting moves into a more standardized, IRS-visible framework.
