Clock is ticking for bitcoin to prevent quantum threat as it could drain 6.9 million BTC including Satoshi’s

Can a network without formal governance coordinate the biggest cryptographic migration in its history? What to know : Quantum computers cannot disrupt bitcoin mining or the blockchain ledger itself, but they could eventually break the cryptography that protects wallet ownership. Roughly 6.9 million bitcoin, including Satoshi Nakamoto’s early holdings and any coins spent from since 2021’s Taproot upgrade, are already exposed to future quantum attacks because their public keys are visible on-chain. Unlike Ethereum, which has a coordinated, well-funded post-quantum migration plan, bitcoin lacks a unified roadmap, and its anti-centralization culture makes it harder to agree on urgent security upgrades before quantum hardware matures.
