The director of one of the schools in China, Lei Hua, was fired after the discovery of an educational system connected to the power grid of devices designed for mining cryptocurrencies.
Teachers from a school in Hunan Province became suspicious because of a strange rumble or buzzing noise in the school building, local media reported.
The search for the noise source led them to the Ethereum cryptocurrency mining devices..
As it turned out, the amount of electricity that costs an institution $ 2,000 is spent on ensuring the operation of these devices..
Earlier, the director was informed of unexpectedly increased electricity bills, but he did not express concern, suggesting that the increased electricity consumption is related to the operation of air-conditioning and heating systems.
