Bitcoin’s price is currently testing resistance levels while holding above key supports. Binance’s weekly price data shows a downtrend over eight weeks paired with lingering volatility. This market structure suggests investors are staying cautious as the cryptocurrency faces not only technical uncertainty but also heated debate over quantum computing risks. That debate revolves around nearly 6.7 to 6.9 million BTC vulnerable to quantum attacks, putting focus on a plan to freeze Satoshi Nakamoto’s estimated 1.1 million bitcoin to shield the network from catastrophic loss, according to Crypto Briefing’s coverage.
“It would hurt the price substantially if the coins were dumped; it’d be a one-time episode and post-quantum bitcoin would recover,” Michael Terpin told Techtimes.

Advancements in quantum computing threaten Bitcoin’s elliptic curve cryptography, which underpins wallet security by stopping miners from deriving private keys from public ones. This technology remains crucial as a Google Quantum AI whitepaper published on March 30, 2026, warned that quantum computers could unlock Bitcoin private keys in as little as nine minutes once they’re viable. That’s expected around 2029, Techtimes reports. Google’s discovery of a circuit optimization enabled this by dramatically cutting quantum computational resources needed—from about 9 million down to fewer than 500,000 physical qubits.
More than 34% of all Bitcoin circulating have their public keys permanently exposed on-chain, making these coins particularly vulnerable. Estimates put the total Bitcoin supply exposed to quantum attacks between 6.7 and 6.9 million BTC. That’s a substantial chunk of the roughly 21 million coins that will ever exist, as Tftc figures highlight.
One steep challenge involves approximately 1.1 million BTC attributed to Bitcoin’s pseudonymous creator, Satoshi Nakamoto. These coins haven’t moved since distribution, locked in wallets tied to public keys revealed on the blockchain. This setup creates a complex security risk: any quantum attacker who cracks Satoshi’s private keys could access a massive sum, potentially dealing irreversible damage to Bitcoin’s market value and reputation. Binance founder Changpeng Zhao has suggested freezing these dormant wallets by enforcing a migration window after upgrading to quantum-resistant protocols. Wallets left inactive for 12 months past this deadline could be frozen, aiming to prevent hostile actors from mobilizing these coins, per Crypto News’ report.
Arguments for and against freezing the coins
Supporters argue that preemptively locking wallets with exposed keys—including Satoshi’s—would stop a sudden quantum attack from dumping millions of BTC onto the market and crashing its value.
BIP-361 and legacy coin migration frameworks
Amid this debate, BIP-361 has emerged as a structured proposal tackling quantum vulnerabilities tied to legacy Bitcoin addresses. Jameson Lopp authored it, submitting the framework to the Bitcoin BIPs repository in April 2026. The plan entails a phased five-year sunset for legacy signature schemes. Any coins not migrated during this period would become permanently frozen. BIP-361 notes this sunset protocol affects over 34% of bitcoin associated with revealed public keys, according to Tftc.
Market and investor implications of the quantum risk
The quantum risk exposing up to 6.9 million BTC introduces a major supply-side concern that market players are factoring into their strategies.
Bitcoin’s foundational promise of absolute scarcity and immutability stands to be shaken. Accepting protocol changes that nullify dormant coins—even ones untouched for 15 years—marks a critical philosophical shift. If the community agrees to these measures, it could weaken the argument that Bitcoin’s consensus rules are absolute, shifting its image from immutable hard money to a somewhat mutable ledger, according to Tftc.
Technical and community outlook
Experts point out that Bitcoin’s elliptic curve cryptography is already under pressure. With quantum computing advancing, the time to take action is quickly running out. Google’s Willow quantum chip currently boasts 105 physical qubits, though that’s still far from the estimated 500,000 qubits needed for effective cryptographic attacks.
Looking ahead: the quantum threat’s timeline and impact
Analysts estimate practical quantum attacks might materialize within 20 to 40 years, considering about a 10% chance of feasible decryption by then, per Techtimes.
What is BIP-361 and would it freeze more than Satoshi’s bitcoin?
BIP-361 outlines a phased five-year sunset of legacy signatures that would permanently freeze unmigrated coins across about 1.7 million BTC in P2PK addresses. This plan includes Satoshi’s estimated 1.1 million BTC as part of this broader set of vulnerable coins.
How many bitcoin are actually vulnerable to a quantum attack today?
Estimates suggest that between 6.7 and 6.9 million BTC are quantum-vulnerable, with over 34% of all Bitcoin already having its public keys permanently exposed on the blockchain. As of March 1, 2026, this makes a substantial portion of Bitcoin susceptible to potential quantum computing attacks.
