Mexican federal prosecutors, the navy and Puebla state police seized 300 cryptocurrency mining machines at a facility in Tlaola, Puebla, that allegedly drew electricity illegally from infrastructure linked to the Nuevo Necaxa federal hydroelectric facility. Authorities also confiscated transformers, medium-voltage equipment and a satellite internet antenna. Local media identified the machines as GPUs, suggesting the site may have mined cryptocurrencies other than BTC, which is typically mined with specialized application-specific hardware. Cryptocurrency mining is legal in Mexico, but prosecutors are preparing electricity-theft charges and investigating whether assets produced at the site were used to launder criminal proceeds. Authorities are also examining nearby municipalities and potentially neighboring states for similar operations. EL PAÍS reported that three other mining operations were dismantled around Puebla and neighboring Tlaxcala during 2025. The case comes amid wider concerns over electricity theft associated with crypto mining, including reported losses for Malaysia’s Tenaga Nasional and an unauthorized mining setup found beneath a Massachusetts school.
