Why Quantum Computers Could Steal Satoshi's Bitcoin First

Satoshi Nakamoto's estimated 1 million Bitcoin holdings could be among the primary targets for future quantum computing attacks because early Bitcoin addresses stored raw, exposed public keys without a modern hashing step. Bitcoin security researcher Justin Drake highlighted in a recent interview that roughly 20,000 early addresses, each containing 50-BTC block rewards, are directly vulnerable to quantum decryption. However, Drake emphasized that regular cryptocurrency holders do not need to panic, as funds kept in unspent fresh hashed addresses remain fully protected until spent. Drake warned market participants against prematurely rushing into unproven post-quantum cryptographic upgrades, noting that hasty implementations could introduce technical bugs and enable scam attempts. Developers are actively evaluating mitigation strategies, including the proposed BIP-361 to gradually freeze legacy quantum-vulnerable addresses, as well as tested solutions like Quantum Safe Bitcoin on private mempools. Analyst estimates suggest approximately 1.716 million Satoshi-era BTC are vulnerable, mitigating fears of broader systemic contagion across modern Bitcoin network wallets.
