Bitcoin’s core developers are openly debating whether to permanently freeze Satoshi Nakamoto’s roughly 1,096,358 BTC, a stash worth about $89 billion with BTC trading near $80,015, before quantum computers can crack the legacy addresses holding it.
The catalyst: Google Quantum AI research published in early 2026 suggests a 500,000-qubit machine could break Bitcoin’s signature scheme, possibly by 2029. Decrypt reported this week that “by the time Bitcoin and other networks are ready to defend themselves, it may already be too late.” Roughly 1.7 million BTC sit in quantum-vulnerable Pay-to-Public-Key addresses, including most of Satoshi’s coins.
Enter BIP-361, the “Post Quantum Migration and Legacy Signature Sunset” proposal introduced in April 2026 by developers including Jameson Lopp. It runs three phases: Phase A blocks new sends to legacy P2PK/P2PKH addresses for three years; Phase B invalidates ECDSA and Schnorr signatures after five years, effectively freezing un-migrated coins; Phase C offers limited ZK-proof recovery tied to seed phrases.
Critics call it confiscation. Paradigm’s Dan Robinson countered in May 2026 with “Provable Address-Control Timestamps” (PACTs), letting dormant holders prove key control without moving coins on-chain. Polymarket traders are skeptical anything ships soon: BIP-360 implementation by year-end 2026 trades at just 14.5%.
The Profit Angle
Headline risk is the trade. A false January 2026 rumor that Satoshi wallets moved 10,000 BTC triggered roughly $1 billion in ETF outflows in a single session before Arkham debunked it. Watch the BIP-361 mailing list, exchange custody policies, and any Patoshi-pattern wallet activity. Quantum-resistant infrastructure plays and dips driven by freeze-rumor flushes are where the asymmetric setups live.
