On-chain analyst James Examine has pushed again towards claims {that a} quantum-enabled sale of Satoshi-era Bitcoin would characterize an existential market shock, arguing that the doubtless sell-side strain is way smaller than the headline numbers recommend.
In an April 23 report titled “Promoting Satoshi’s Stack,” Examine examined the talk over whether or not Bitcoin ought to freeze quantum-vulnerable cash if a cryptographically related quantum pc, or CRQC, turns into viable. The dialogue has intensified round older Bitcoin outputs whose public keys are uncovered, together with cash from Bitcoin’s earliest years that many market individuals affiliate with Satoshi Nakamoto.
Bitcoin Quantum Fears Over Satoshi’s Cash Overblown?
Examine’s central argument is just not that quantum threat must be ignored. He mentioned Bitcoiners ought to assist “the talk, improvement, and preparation” of credible post-quantum options. However he rejected the concept that susceptible cash routinely translate right into a market-ending promote occasion.
“Quantum bulls usually quote the 6.9M susceptible cash as being a sword of Damocles that threatens to kill Bitcoin ought to a CRQC ever come to market,” Examine wrote. “As with most issues, there’s a tonne of misplaced nuance, and the satan is completely within the particulars.”
Based on the report, roughly 6.934 million BTC at the moment fall into classes that may very well be susceptible to long-range quantum assaults as a result of their public keys are uncovered. That features 1.716 million BTC in Satoshi-era P2PK outputs, 214,000 BTC in Taproot addresses, and about 4.996 million BTC held in reused addresses.
Examine argues that the total 6.934 million BTC determine is greatest understood as a theoretical higher sure somewhat than a practical market-risk estimate. Taproot is comparatively new, he famous, which means many homeowners are doubtless nonetheless lively and capable of migrate. Reused addresses, in the meantime, doubtless embrace massive volumes managed by exchanges, custodians, ETFs and different entities with each the inducement and capability to improve when post-quantum paths develop into out there.
“The actual threat are the 1.716M Satoshi Period P2PK cash, which many liken to a sunken galleon stuffed with gold, there for the taking if the lock may be pried open,” Examine wrote.
Even underneath a extreme assumption that every one 1.716 million P2PK cash are stolen and offered, Examine mentioned the market influence would doubtless be important however not deadly. He in contrast the haul towards revived provide, URPD shifts, trade deposits and buying and selling volumes, discovering that the total P2PK steadiness is broadly equal to about 60 to 90 days of sell-side exercise seen in Bitcoin bull markets or late-stage bear-market capitulations.
“There isn’t a doubt {that a} QC attacker promoting all of the P2PK cash would negatively influence the worth. It in all probability creates a bear market. Nonetheless, the place will, I push again strongly, is it’s nowhere close to the ‘end-of-days’ deadly sell-side many quantum bulls within the debate appear to say.”
Examine pointed to revived provide, which measures cash held for not less than six months which can be spent on a given day, as one lens for estimating Bitcoin’s capability to soak up older provide. He mentioned a baseline of roughly 10,000 BTC per day is typical even in bear-market circumstances, whereas bull-market profit-taking can push revived provide above 20,000 to 30,000 BTC per day.
On that foundation, the sale of Satoshi-era P2PK cash would characterize a big however not unprecedented demand take a look at. Examine additionally cited current 90-day cost-basis turnover, arguing that greater than 2.3 million BTC had moved to new patrons between $60,000 and $80,000 because the Feb. 5, 2026 sell-off, exceeding the P2PK steadiness by 1.36 instances.
The report additionally discusses the proposed “hourglass” compromise within the BIP-360 debate, underneath which miners might embrace no a couple of P2PK output per block. With about 38,000 P2PK outputs, Examine estimated that such a mechanism would take roughly 264 days to totally exhaust the set, roughly in keeping with an optimistic post-quantum migration timeline for the broader Bitcoin community.
For Examine, the quantum debate finally goes past market mechanics. The sell-side argument, he suggests, is weaker than usually claimed; the more durable query is whether or not Bitcoin ought to protect property rights even when outdated cash develop into susceptible, or intervene earlier than another person can take them.
“To the parents who declare we MUST freeze the cash due to the sell-side, I’d encourage you to place some numbers to your claims,” he wrote. “As an alternative, the precise thrust of this debate is across the rules of what Bitcoin is.”
At press time, BTC traded at $77,869.
