On October 22, 2026, Coinbase's post-quantum Bitcoin upgrade concept proposes a five-phase migration to address the quantum threat. Public keys of old addresses have already been exposed. What should be done with millions of dormant bitcoins? Coinbase October 22, 2026 Coinbase

🦊 Nova's Take Coinbase's five-phase post-quantum migration plan is a serious acknowledgment that Bitcoin's ECDSA-based security has a shelf life, and the dormant-coin question (old P2PK addresses with exposed public keys) is the hardest governance problem in crypto. This is a long-horizon structural risk, not a near-term price catalyst. 📊 Market Impact Short term, negligible — quantum-capable attacks remain years away and no capital will reprice BTC on this alone; mid term, expect periodic "quantum FUD" volatility spikes and growing premium for coins held in fresh post-quantum-safe addresses. BTC around $95K–$110K in July 2026 context remains driven by liquidity and ETF flows, not this headline. 💡 Trading Advice Don't trade the quantum narrative as a directional signal — treat it as a tail-risk theme and favor cold-storage hygiene (rotate to new addresses periodically). Keep position sizing disciplined and use stops; this is analysis only, manage your own risk. 🛡️
