Brazilian law enforcement raided an illegal Bitcoin mining operation in São Paulo state on May 20, seizing roughly 1,400 mining rigs that had been quietly stealing enormous amounts of electricity from the local power grid. The stolen power totaled approximately 2 gigawatt-hours, enough to supply about 2,000 households for a full month.
Inside the operation
The São Paulo State Property Crime Investigation Department, known by its Portuguese acronym DEIC, led the bust in coordination with regional utility CPFL Piratininga. The operation was running nine three-phase transformers with a combined capacity of 8,470 kVA.
No specific individuals or organizations have been publicly named in connection with the seizure. The investigation appears to be ongoing, with authorities focused on the electricity theft rather than the mining activity itself.
Legal mining, illegal power
Bitcoin mining is perfectly legal in Brazil. The crime here wasn’t running the rigs. It was stealing the electricity to power them.
The timing of this bust is notable. In March 2026, Brazil passed a law that permits the seizure and liquidation of digital assets linked to criminal activities. Proceeds from those liquidations are earmarked for funding public security efforts.
What this means for investors
Enforcement actions like this one can benefit legitimate miners. Every illegal operation that gets shut down removes hash rate from the network, marginally improving the economics for everyone playing by the rules. When 1,400 rigs go offline, that’s computing power no longer competing for block rewards.
The March 2026 asset seizure law creates a template that other countries may follow. If governments realize they can fund public security by liquidating seized crypto, the incentive to crack down on illegal mining operations only grows.
