Bitcoin hash rate slides during U.S. winter storm while markets shrug off mining disruption

The temporary loss of mining power underscores academic concerns that geographic and pool concentration can magnify infrastructure failures, though markets showed little immediate reaction. What to know : Bitcoin’s hashrate fell about 10 percent during a U.S. winter storm, underscoring how local power disruptions can strain the network’s capacity to process transactions. Researchers have shown that concentrated mining, as seen in a 2021 regional outage in China, can lead to slower block times, higher fees and broader market disruptions. With a few large pools now controlling most of Bitcoin’s hashrate, the network is increasingly vulnerable to localized infrastructure failures, even as the price of BTC remains largely unaffected in the short term.
