Tenaga Nasional Bhd (TNB), one of the largest electricity suppliers in Malaysia, has raided 33 bitcoin mining premises suspected of stealing power, Malay Mail reported Wednesday. The miners bypassed meters and used electricity directly from TNB, which resulted in a loss of 3.2 million Malaysian ringgit ($760,736) for the supplier, according to The Block. One location, for instance, was using 1,500 Amp (ampere) of unmetered electricity while the meter was only showing 3 Amp.
