São Paulo Police Confiscate 1,400 Illegal Bitcoin Mining Rigs After Massive Power Theft

*TL;DR: São Paulo police seized about 1,400 Bitcoin mining rigs and recovered 2 gigawatt‑hours of electricity stolen from the grid, under a law that lets the state liquidate crypto linked to crime.

Context Brazil permits Bitcoin mining, but stealing electricity to power the rigs is illegal. On May 20, the São Paulo State Property Crime Investigation Department (DEIC) teamed with utility CPFL Piratininga to raid a covert mining farm in the state. The operation had been siphoning power from the public grid, a crime that directly impacted local consumers.

Key Facts - Investigators confiscated roughly 1,400 mining rigs, each designed to solve cryptographic puzzles that secure the Bitcoin network. - The farm consumed about 2 gigawatt‑hours of electricity, enough to run roughly 2,000 homes for a month. - Nine three‑phase transformers, together rated at 8,470 kVA, fed the illegal setup. - No individuals or companies have been publicly identified; the probe remains focused on the electricity theft. - A law enacted in March 2026 authorizes seizure and liquidation of digital assets tied to criminal activity, directing proceeds to public‑security budgets.

What It Means The shutdown removes a significant chunk of hash rate—computing power that competes for Bitcoin block rewards—from the network, marginally improving profitability for compliant miners. By converting the seized crypto into funds for law‑enforcement, Brazil creates a financial incentive to target similar operations. The March 2026 legislation could serve as a model for other jurisdictions seeking to fund security through crypto asset forfeiture. Watch for how the seized rigs are liquidated and whether the proceeds are earmarked for further anti‑theft initiatives.

*Future monitoring will focus on the legal outcomes for the confiscated assets and any ripple effects on Brazil’s broader cryptocurrency regulatory landscape.*
