Mexican Cartels Turn to Clandestine Cryptocurrency Farms to Launder Money
A clandestine cryptocurrency mining operation discovered in the mountains of Sierra Norte de Puebla has raised alarms about a new funding route for organized crime in Mexico: the use of digital assets to launder illicit capital. Authorities located the site, situated in the municipality of Tlaola, after the intense mechanical noise and disproportionate electricity consumption caught the attention of local residents. According to a report by Reuters, the amount of energy required to operate and cool the equipment far exceeded the demand of nearby rural communities.
A Discovery with Sophisticated Machinery
In the property, authorities found 300 graphics processing units (GPUs), 80 medium-voltage terminals, and eight satellite antennas, all the necessary equipment to compete against millions of machines in generating cryptocurrencies like bitcoin. Although this operation is modest by international commercial standards, it represents the fourth such farm detected in the region since last year, suggesting a pattern rather than an isolated case. Security analyst David Saucedo noted that the level of sophistication detected indicates technical expertise and financial backing typical of large-scale criminal organizations. The Attorney General's Office refrained from commenting on the case, stating that the investigation is ongoing.
Electricity Theft: The Key to the Business
One of the central findings of the investigation points to possible electricity theft from a nearby hydroelectric dam. According to specialists, electricity represents the highest cost in cryptocurrency mining, so stealing it from the grid virtually eliminates the main operational expense. Samuel León, an expert in energy theft from the Ibero-American University, explained that if the supply was taken illegally, the costs of maintaining the operation would be practically zero. The Bitcoin Electricity Consumption Index, developed by the University of Cambridge, estimates that producing a single bitcoin costs around 45,000 dollars, a figure that still leaves a wide profit margin considering that the cryptocurrency is currently priced around 78,000 dollars.
A Growing Global Phenomenon
The case in Puebla fits into a broader trend. According to blockchain analysis firm Chainalysis, illicit transactions involving cryptocurrencies more than tripled during 2025, reaching an estimated 154 billion dollars received by addresses linked to criminal activities, compared to 59 billion dollars the previous year. Caio Motta, a Latin America specialist at Chainalysis, explained that Latin American cartels have found cryptocurrencies to be an attractive tool for laundering money, especially in areas with cheap energy or under the control of organized crime, where it is easier to steal electricity and install large-scale mining infrastructure.
Hidden in the Mountains, but Not in Silence
The remote location of the farm, nestled among dense forests and scattered communities, made it an almost perfect hideout. However, residents of nearby towns—who requested anonymity for fear of reprisals—reported that the hum of the equipment could be heard up to a kilometer away. The other three farms discovered in the region in the past year were also located near the same hydroelectric dam, in northern Puebla. Local authorities indicated that they are already collaborating with neighboring states to identify possible additional operations. Similar cases have been reported in Brazil, the United States, and Southeast Asia, including a large-scale operation against bitcoin mining in Thailand that spanned five provinces.

An Expanding Threat
For Motta, the growing global use of cryptocurrencies—now increasingly accessible—will likely raise crimes linked to these assets to record levels in the coming years. However, he noted that authorities are also improving their capabilities to track digital transactions, which could balance the scales in the fight against such financial crimes. The case in Puebla thus adds to a growing list of findings documenting how Mexican organized crime diversifies its sources of income, beyond drug trafficking and extortion, into the realm of digital finance.
