JUST IN: Bitcoin and crypto firms ask AI labs early access to their most powerful models to fight hackers. They say strong AI can find Bitcoin software flaws, but security rules often block trusted researchers from using it. They argue hackers do not face the same limits, giving them a better chance of finding and exploiting flaws first. Support has grown from 40+ to 77 signatories, including Coinbase, Strategy, MARA, ARK Invest among others.(Coin Bureau)
