CZ Floats Freezing Satoshi’s 1.1M BTC Over Quantum Risks

On June 20, 2026, Binance founder Changpeng Zhao renewed calls for Bitcoin to adopt quantum-resistant cryptography and freeze unmigrated legacy wallets after a six- to twelve-month grace period. The proposal, first aired on the June 18 Galaxy Brains podcast, would retire old addresses and potentially lock Satoshi Nakamoto’s estimated 1.1 million BTC if they remain inactive. While supporters see it as essential protection against future quantum theft, critics warn the measure would breach immutability and amount to confiscation. The debate underscores growing long-term protocol concerns even as current quantum machines pose no immediate threat to the network. Market impact centers on governance risks rather than immediate price moves, with Satoshi’s stash valued near $70 billion at recent levels.
