Onchain analyst and early Bitcoin adopter Willy Woo is warning that rising consideration to quantum computing dangers is beginning to weigh on Bitcoin’s long-term valuation case in opposition to gold.
Woo argued in a Monday X submit that markets had begun to cost within the threat of a future “Q‑Day” breakthrough — shorthand for the second when a robust sufficient quantum pc exists to interrupt right now’s public key cryptography.
Roughly 4 million “misplaced” Bitcoin (BTC) — cash whose non-public keys are presumed gone — may very well be dragged again into play, Woo argued, if a robust quantum pc might derive non-public keys from uncovered public keys, undermining a part of Bitcoin’s core shortage narratives.
He estimated solely a couple of 25% likelihood that the community would conform to freeze these cash by way of a tough fork, one of the contentious points in Bitcoin governance right now.
Q‑day threat and “misplaced” cash
In keeping with blockchain researchers, the 4 million uncovered cash signify round 25%-30% of the Bitcoin provide and are held in addresses whose public keys are already seen onchain, making them among the many first in danger in a quantum assault situation.

But any transfer to freeze these cash would upend lengthy‑standing norms round fungibility, immutability and property rights.
Freezing the cash might provoke deep splits between these prioritizing backward‑suitable fixes (upgrades that protect current guidelines and cash with out invalidating previous transactions or requiring a contentious exhausting fork), and people prepared to rewrite guidelines to guard early balances.
With a 75% probability of the cash remaining untouched, traders ought to assume, Woo stated, a non‑trivial likelihood that an quantity of BTC equal to roughly “8 years of enterprise accumulation” turns into spendable once more.
It’s a prospect that’s already being priced in as a structural low cost on BTC’s valuation versus gold for the following 5 to fifteen years, Woo argued, which means that Bitcoin’s lengthy‑time period tendency to achieve buying energy when measured in ounces of gold is now not in play.
Bitcoin’s submit‑quantum migration path
Many core builders and cryptographers stress that Bitcoin doesn’t face an imminent “doomsday” state of affairs and has time to adapt.
The rising roadmap for a submit‑quantum migration shouldn’t be a single emergency exhausting fork, they argue, however a phased course of, finally steering the community towards new handle codecs and key administration practices over a multi‑yr transition.
Even when quantum did arrive ahead of anticipated and the cash have been recirculated, different Bitcoiners, comparable to Human Rights Basis chief technique officer Alex Gladstein, argue that it’s unlikely they might be dumped onto the market.
Gladstein sees a extra probably situation the place the cash are amassed by a nation-state quite than instantly bought.

Quantum threat goes mainstream in macro
Nonetheless, Woo’s warning lands in a market the place Bitcoin is buying and selling virtually 50% off its all-time excessive, and quantum has already moved from a distinct segment concern to a mainstream threat consider institutional portfolios.
In January, Jefferies’ longtime “Greed & Worry” strategist Christopher Wooden minimize Bitcoin from his flagship mannequin portfolio and rotated the place into gold, explicitly citing the likelihood that “cryptographically related” quantum machines might weaken Bitcoin’s retailer of worth case for pension‑model traders.
