Bitcoin experts debate freezing Satoshi’s 1M bitcoin amid quantum threat A Google quantum AI warning has reignited a long-simmering argument about whether Bitcoin should freeze wallets tied to its anonymous creator Bitcoin has survived exchange collapses, regulatory crackdowns, and roughly a dozen declared deaths. Now it faces a philosophical crisis with actual technical teeth: what happens when quantum computers get powerful enough to crack Bitcoin’s cryptography, and millions of coins, including those belonging to Satoshi Nakamoto, become sitting targets? The threat is real, and the clock is ticking A Google Quantum AI whitepaper has given the community something concrete to argue about. The report warns that quantum computers could derive Bitcoin private keys from public keys in as little as nine minutes, with that capability expected to become realistic by 2029. Here’s the thing about Bitcoin’s security model: it relies on elliptic curve cryptography, a system where knowing someone’s public key doesn’t let you work backwards to their private key. Quantum computers, particularly those running Shor’s algorithm, can do exactly that math, in theory breaking open any wallet whose public key is exposed on the blockchain. Early Bitcoin addresses, known as P2PK addresses, are especially vulnerable because they expose public keys directly. More recent address formats partially obscure the public key behind a hash, buying some time, but not immunity. Estimates put the total quantum-vulnerable Bitcoin supply somewhere between 6.7 and 6.9 million BTC. That’s a meaningful slice of the roughly 21 million coins that will ever exist. The Satoshi problem Nested inside that larger number is a more emotionally loaded subset: approximately 1.1 million BTC widely attributed to Satoshi Nakamoto, sitting in wallets that have never moved and whose public keys are known. Binance co-founder Changpeng Zhao has proposed a specific solution. His suggestion: give the community a migration
