Iran will offer a $24 bounty to those who report illegal cryptocurrency mining activities as a severe heatwave leads to power shortages, PANews reported. Temperatures soared to 113 degrees Fahrenheit (45 degrees Celsius) in some areas, putting pressure on the power grid.

Mostafa Rajabi Mashhadi, CEO of Iran’s state-run electricity company Tavanir, said individuals who report unauthorized cryptocurrency mining equipment will receive a bounty of 1 million tomans (about $24).

Mashhadi said that speculators used subsidized electricity and public networks to conduct unauthorized mining, causing an abnormal surge in electricity consumption and causing serious damage and problems to the power grid. 230,000 illegal crypto mining devices have been found, consuming up to 900 megawatts of electricity, equivalent to the electricity consumption of a province with 1.4 million residents.

Iranian authorities frequently announce the discovery of illegal crypto miners, many of whom take advantage of schools and mosques that have free or subsidized electricity, according to Iran International.
