Bitcoin Could Survive Sale Of Satoshi’s Coins, On-Chain Expert Says

On-chain analyst James Check argues a quantum-enabled sale of Satoshi-era BTC would be painful but not market-ending. While ~6.934M BTC are theoretically vulnerable (including 1.716M in Satoshi-era P2PK outputs, 214k in Taproot and ~4.996M from reused addresses), Check treats the total as an upper bound and says many coins are likely accessible to active custodians or exchange migration. Even if all 1.716M P2PK coins were stolen and sold, that would approximate 60–90 days of sell-side activity seen in prior market stress — large but not existential. Check cites typical revived supply of ~10k BTC/day (20–30k in bull profit‑taking) and notes >2.3M BTC moved into new buyers between $60k–$80k since Feb 5, 2026, exceeding the P2PK balance. The piece reframes the debate toward policy and property‑rights choices (e.g., BIP‑360 “hourglass” proposal) rather than panic over immediate price annihilation.
