Romanian tax authorities have discovered a large-scale, illegal cryptocurrency mining operation in Satu Mare. Inspectors from the General Directorate for Fiscal Anti-Fraud (DGAF) uncovered over 400 pieces of mining equipment within a derelict building. The operation was systematically conducted and undeclared, deliberately avoiding tax obligations. The facility consumed a significant amount of electricity due to the constant operation of the specialized hardware. Authorities indicate the operation was actively evading fiscal responsibilities. The discovery highlights growing concerns about the energy consumption and tax implications of unregulated cryptocurrency mining. Further investigations are underway to determine the full extent of the operation and identify those responsible.
