According to The Block, Bitcoin mining company Iris Energy has stopped powering mining machines with more than $100 million in loan collateral, freeing up about 90 MW of power capacity and planning to use it to explore other opportunities, involving an additional 7.5 EH/ s contract mining machine for self-mining Bitcoin. Foresight News previously reported that on November 8, Iris Energy said it had received a default notice of $103 million in outstanding debt, mainly due to the fact that the production capacity of the two financing bitcoin miner mining companies operated by Iris Energy could not provide enough income for miners.
