Cryptography researcher Justin Drake said in a post on X that the blockchain industry should calmly begin planning for a "bunker mode" setup. He advised large holders to move most funds into fresh addresses that have never signed a transaction and whose public keys remain hidden behind a hash. After any future signature, he said, the remaining funds should be moved again to a new address. Drake argued that AI is accelerating breakthroughs in mathematics and that ECDSA could, in theory, be broken by classical algorithms before quantum computing reaches the so-called "Q-Day." In his worst-case scenario, that could happen in months rather than years, with large GPU clusters potentially recovering private keys in about a week. He also said there is no need for panic or rushed migration, and added that Binance, Bitbank, Robinhood, Bitfinex, and Tether could use the moment to strengthen their cold-wallet setups.

At the same time, he said there is no need for panic or a rushed migration. He also wrote that Binance, Bitbank, Robinhood, Bitfinex, and Tether could use the opportunity to harden their cold wallets.
