BTC security under di quantum threat wey be “harvest now, decrypt later”

Security investor Andrew Gault (ZeroTier) talk say BTC security wahala pass wallet hacks — e reach di encrypted identity, authentication, and digital-signature layers wey exchanges, bridges, and custodians dey use. Di koko wahala na "harvest now, decrypt later": attackers fit gather encrypted inter-system traffic, authentication records, and proofs today, den decrypt or forge dem when quantum tech sharp well. One Google study wey report mention talk say one strong quantum computer fit extract BTC private keys from public addresses in as small as nine minutes, wey make people look again for about ~6.9M BTC wey dem dey report say dey for public addresses and say industry never get post-quantum migration plan. Google reportedly dey target finish post-quantum cryptography by 2029, dem prioritize wire-level signing and authentication. But major exchanges and custody providers never publicly commit to similar timelines to upgrade their signing infra. Ethereum (ETH) dementioned as don start community-driven post-quantum efforts. Risk modelling: Citi estimate say one quantum-enabled attack against top U.S. bank fit trigger $2T–$3.3T cascade losses for financial system, while Global Risk Institute put probability of cryptographically relevant quantum computing by 2034 at 19%–34%. CoinShares analysis dey used to calm panic, dem argue say fears of direct BTC wallet key breaches fit be overstated and any immediate market impact fit be limited (less than ~10,000 BTC), but report still flag "proof-layer" weak points as likely BTC security exposure path. For traders, dis one keep BTC security for spotlight: headline na bearish sentiment risk, but near-term price impact fit remain limited unless exchanges/custodians give concrete post-quantum timelines.
