Bitcoin miners are looking to activities other than bitcoin mining to make up for the income gap before and after the halving, such as hosting artificial intelligence computers. Shares of the top five crypto miners have all rallied in recent days as bitcoin prices have rebounded, with the only stock lagging behind being Iris Energy Ltd (IREN), which fell 15% after Culper Research released a report last week revealing its short position in IREN. Culper is bearish because researchers believe Iris' Childress, Texas plant is not suitable for artificial intelligence (AI) or high-performance computing (HPC).
