Authorities in the Spanish town of Santiponce busted upon a cryptocurrency mining operation and seized €50,000 worth of equipment. It was initially suspected to be a marijuana farm due to its high energy consumption. The miners were found to be stealing €2,000 worth of power every month via an illegal electricity connection.
