Bitcoin mining company IREN (formerly Iris Energy) fell 24% on the Nasdaq after a report from Culper Research accused the company of being "grossly overvalued" and failing to invest in AI. Culper claims that IREN invested less than $1 million per megawatt to build its center and promised to complete a similar center for almost the same price. The report also accuses IREN of being "grossly overvalued" and should be 52-79% cheaper. 😕
