Bitcoin (BTC) Quantum Risk Warning: Claim That 20–30% P2PK Supply Could Be Seized in 2–8 Years — What Traders Should Monitor

According to Charles Edwards (@caprioleio), up to 20–30% of BTC held in legacy P2PK outputs could be taken by a future quantum computer within 2–8 years, and he proposes either allowing theft-related dumping or enforcing a migration window that burns unmigrated coins (source: Charles Edwards on X, Oct 15, 2025). According to Bitcoin Wiki, P2PK outputs reveal public keys on-chain, leaving any unspent P2PK UTXOs inherently exposed if Shor’s algorithm breaks secp256k1 ECDSA (source: Bitcoin Wiki, Pay-to-Pubkey). According to NIST’s Post-Quantum Cryptography program, no cryptographically relevant quantum computer exists today, though ECDSA is not quantum-safe and migration to standardized PQC schemes like CRYSTALS-Dilithium will be required once timelines warrant (source: NIST PQC status reports, 2022–2024). According to Roetteler et al. (Microsoft Research), breaking a single secp256k1 key demands very large fault-tolerant quantum resources beyond current hardware, making the specific 2–8 year horizon uncertain for traders to price (source: Roetteler et al., 2017, Quantum Resource Estimates for ECC).
