On-chain analyst James Verify has pushed again towards claims {that a} quantum-enabled sale of Satoshi-era Bitcoin would signify an existential market shock, arguing that the seemingly sell-side stress is much smaller than the headline numbers counsel.
In an April 23 report titled “Promoting Satoshi’s Stack,” Verify 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?
Verify’s central argument shouldn’t be that quantum threat needs to be ignored. He mentioned Bitcoiners ought to help “the talk, growth, and preparation” of credible post-quantum options. However he rejected the concept weak cash routinely translate right into a market-ending promote occasion.
“Quantum bulls usually quote the 6.9M weak cash as being a sword of Damocles that threatens to kill Bitcoin ought to a CRQC ever come to market,” Verify wrote. “As with most issues, there’s a tonne of misplaced nuance, and the satan is completely within the particulars.”
In keeping with the report, roughly 6.934 million BTC at the moment fall into classes that may very well be weak 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.
Verify argues that the complete 6.934 million BTC determine is greatest understood as a theoretical higher sure relatively than a sensible market-risk estimate. Taproot is comparatively new, he famous, which means many house owners are seemingly nonetheless energetic and capable of migrate. Reused addresses, in the meantime, seemingly embody giant volumes managed by exchanges, custodians, ETFs and different entities with each the motivation and capability to improve when post-quantum paths change into accessible.
“The true threat are the 1.716M Satoshi Period P2PK cash, which many liken to a sunken galleon filled with gold, there for the taking if the lock could be pried open,” Verify wrote.
Even beneath a extreme assumption that every one 1.716 million P2PK cash are stolen and offered, Verify mentioned the market affect would seemingly be important however not deadly. He in contrast the haul towards revived provide, URPD shifts, change deposits and buying and selling volumes, discovering that the complete 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 any doubt {that a} QC attacker promoting all of the P2PK cash would negatively affect the worth. It in all probability creates a bear market. Nevertheless, 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 assert.”
Verify pointed to revived provide, which measures cash held for at the least six months which can be spent on a given day, as one lens for estimating Bitcoin’s potential to soak up older provide. He mentioned a baseline of roughly 10,000 BTC per day is typical even in bear-market situations, 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 signify a big however not unprecedented demand check. Verify additionally cited latest 90-day cost-basis turnover, arguing that greater than 2.3 million BTC had moved to new consumers between $60,000 and $80,000 because the Feb. 5, 2026 sell-off, exceeding the P2PK steadiness by 1.36 occasions.
The report additionally discusses the proposed “hourglass” compromise within the BIP-360 debate, beneath which miners might embody no a couple of P2PK output per block. With about 38,000 P2PK outputs, Verify estimated that such a mechanism would take roughly 264 days to completely exhaust the set, roughly in step with an optimistic post-quantum migration timeline for the broader Bitcoin community.
For Verify, the quantum debate finally goes past market mechanics. The sell-side argument, he suggests, is weaker than usually claimed; the tougher query is whether or not Bitcoin ought to protect property rights even when previous cash change into weak, or intervene earlier than another person can take them.
“To the oldsters 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.
