The Texas-based Rhodium Enterprises bitcoin mining company has filed for bankruptcy, disclosing debts between $50 and $100 million and total assets between $100 and $500 million. The company had tried to begin restructuring, but was not able to reach agreement among shareholders, and so decided to enter bankruptcy.Bitcoin mining has been an extremely challenging business in recent times, partly due to volatile crypto prices over the last few years, and due to diminishing miner rewards following the April halving event.Rhodium Enterprises had been showing signs of trouble, including failing to make scheduled loan payments earlier this month. In December 2023, a dispute between them and a subsidiary of the Riot Platforms bitcoin mining group culminated in armed security removing Rhodium employees from a bitcoin mining facility in Rockdale, Texas, where Rhodium was leasing bitcoin miners. The case was later sent to arbitration.
