Malaysia Faces Over $1 Billion Loss from Unauthorized Cryptocurrency Mining

Malaysia’s national power company, Tenaga Nasional Bhd (TNB), has revealed devastating losses exceeding $1 billion due to unauthorized cryptocurrency mining activities. These activities have drained significant power resources across the nation, with losses amounting to RM 4.57B and affecting over 13,827 premises between 2020 and August 2025. The surge in illicit Bitcoin mining is attributed to illegal operations circumventing conventional electricity meters, which are subject to the Electricity Supply Act.
