币界网报道：Bitcoin miners are experiencing a 20% drop in hashrate as extreme summer heat forces operational shutdowns across major mining hubs in Texas and China. Rising temperatures have strained power grids, prompting authorities to curtail electricity supply to mining facilities. Marathon Digital and Riot Platforms reported temporary closures of some Texas sites, while Chinese miners face similar disruptions. Analysts estimate the global Bitcoin network hashrate declined from 600 EH/s to 480 EH/s since June. The reduced mining activity has slightly improved profitability for remaining operators, with mining difficulty expected to adjust downward in the next recalibration. Industry experts warn such climate-related disruptions may become more frequent, pushing miners toward sustainable energy solutions.
