Argo Blockchain's CEO, Thomas Chippas, has resigned after 14 months due to ongoing financial difficulties. The company's CFO, Jim MacCallum, will serve as interim CEO until a permanent replacement is found. During Chippas's tenure, efforts were made to repay loans early and improve financial conditions, but the company continues to struggle with a net loss of $6.3 million in Q3 2024, a 28% decrease in revenue compared to the previous year, and a significant drop in mining profit margins from 58% to 8%.
