Binance founder Changpeng Zhao raised one of the most charged questions in Bitcoin's history on June 18, during an appearance on Galaxy Research's Galaxy Brains podcast. His proposal: after Bitcoin upgrades to quantum-resistant cryptography, give the network six to twelve months for holders of vulnerable addresses to migrate their funds — then freeze whatever hasn't moved.
In practice, that primarily means Satoshi Nakamoto's coins. Roughly 1 million BTC sit across about 22,000 addresses that haven't been touched since Bitcoin's earliest days. These are particularly exposed because their public keys were once visible directly on the blockchain — precisely the data a quantum computer could theoretically use to derive the corresponding private key and drain the wallet. At current prices, we're talking about roughly $65 billion.
The quantum threat became more concrete in March 2026, when Google Quantum AI published research estimating that a machine with around 500,000 qubits could extract a Bitcoin private key from its public counterpart within minutes. That hardware doesn't exist yet, but the trajectory is clear enough that CZ thinks the community should set rules now rather than scramble after a breach.
The freeze logic follows from that: if an attacker ever cracks old keys and suddenly controls 1 million BTC, dumping that on the market at once would be devastating. Locking those coins under protocol rules removes the scenario entirely. This is where the real argument begins.
Alex Thorn of Galaxy Digital, who hosted the podcast, pushed back directly: locking someone's coins without consent is confiscation, regardless of the rationale behind it. For much of the Bitcoin community, property inviolability isn't just a preference — it's a foundational principle, the thing that distinguishes Bitcoin from every legacy financial system.
CZ has no authority to change Bitcoin's protocol. What he has is a platform, and he's used it to force the question into the open. Any real change would require years of developer consensus, miner adoption, and node-level support. But the fact that figures like CZ and Thorn are debating this publicly signals something meaningful: quantum risk is being treated as a concrete policy problem, not a future footnote. The answer — whose interests come first when they conflict — will need to exist before the machines are powerful enough to make it urgent.
