The real-world costs of the digital race for bitcoin

In Texas, the computers kept running until just after midnight. Then the state’s power grid operator ordered them shut off, under an agreement that allowed it to do so if the system was about to fail. In return, it began paying the bitcoin company, Bitdeer, an average of $175,000 an hour to keep the computers offline. Over the next four days, Bitdeer would make more than $18 million for not operating, from fees ultimately paid by Texans who had endured the storm.
