Iran’s smog, blackouts made worse by power-sapping crypto mining

Outages have been compounded by cryptocurrency mining, which uses banks of high-powered computers. Cities across Iran have been cloaked in thick layers of toxic smog and darkened by blackouts, as the alleged use of low-quality fuel and power-sucking cryptocurrency mining deepen the country’s hardships.
