Despite improving macro conditions, including Brent crude futures for October dropping as much as 7.3% to $81.55 a barrel following fresh U.S.-伊朗 talks, Bitcoin and Ether failed to rally. The crypto market remains rattled by a Coldcard hardware wallet exploit, with observed losses from sweeps against Coldcard-generated addresses reaching nearly $89 million (1,367 BTC) across 4,585 addresses. Bitcoin dropped from a Sunday high of $63,600 to $62,800 on Monday, down 1% on the day and 4% over the past week. Ether fell over 1% to $1,858, down 5% on the seven-day view. Oil and Treasury yields fell after the U.S.-伊朗 talks eased inflation fears, typically a positive signal for crypto, but the ongoing wallet exploit appears to be the dominant market drag.
