The Chinese energy company accidentally discovered an illegal connection of one of the apartments to the power grid. Further testing showed that the energy was needed to extract the crypto currency. In the published photos, you can count 56 smartphones and 15 “asikov”, which were the main consumers of electricity.
As the South China Morning Post writes , the unknown could illegally spend 32,940 kWh. At the same time, extraction of one bitcoin will require approximately 18,000 kWh. The police are investigating the crime.
