Mexican Police Seize 300 GPUs in Hidden Crypto Farm

Mexican police identified a hidden cryptocurrency farm in the Sierra Norte region of Puebla state. The operation was concealed within the dense green mountain forests. Investigators found 300 graphics processing units inside a ramshackle building. The site also housed 80 medium-voltage terminals and eight satellite antennae.

This discovery marks the fourth such facility found in the area since early last year. The machinery generated loud mechanical noise audible from one kilometer away. Residents reported hearing the whirring of the equipment near a sparsely traveled gravel road. The location is approximately two kilometers from the nearest village.

Energy theft drives operational costs

Electricity is the primary expense for crypto mining operations. Energy prices have risen globally, making power theft a critical factor for profitability. Samuel Leon, an energy theft expert at Iberoamericana University, stated that stolen power makes costs negligible. Mexican authorities are currently investigating potential theft from a nearby hydroelectric dam.

The cost to mint a single bitcoin is estimated at nearly $45,000. With market prices hovering around $78,000, the margin remains substantial. This economic incentive drives criminal groups to establish large-scale infrastructure. They target regions with cheap electricity or weak grid oversight.

Rising illicit crypto transaction volumes

Illicit cryptocurrency transactions more than doubled in 2025. Addresses linked to criminal activity received an estimated $154 billion. This figure represents a sharp increase from $59 billion in the previous year. Chainalysis identified sanctions evasion as a major driver of this growth.

Latin American cartels are increasingly using crypto transfers to launder money. Caio Motta, a Latin American specialist at Chainalysis, noted this shift. Criminal groups are extending their reach beyond traditional drug trafficking. They are entering the financial crime sector with new sophistication.

Cartel sophistication in financial crime

David Saucedo, a security analyst, described this as a new level of sophistication. Setting up such an operation requires significant technical expertise. It also demands backing from well-financed groups. Mexico’s federal attorney’s office declined to comment due to an active investigation.

The dense forest of the Sierra Norte provides an ideal hiding spot. Scattered communities and difficult terrain hinder detection. The combination of remote location and technical capability poses a new challenge for law enforcement. GN markets/crypto (en-US) reports that these hidden farms are becoming a growing frontier in Mexico’s fight against organized crime.
