Iran is waging a domestic war against illegal cryptocurrency mining operations that are draining its power grid at a critical moment, with authorities now offering rewards for tips about unauthorized mining farms. The country's Deputy Minister of Energy, Mostafa Mashhadi, revealed this week that the government has "plans in place" to identify and shut down illegal digital currency mining operations, according to a report from Iran's Fars news agency.

Why Is Iran's Illegal Mining Problem So Severe?

The scale of unauthorized mining in Iran is staggering. According to Akbar Hasan Beklou, CEO of Tehran Province Electricity Distribution Company, Iran now hosts over 427,000 Bitcoin (BTC) mining devices consuming more than 1,400 megawatts of power, with 95% operating illegally. These mining farms are often disguised as industrial operations and benefit from subsidized energy intended for legitimate industries, making Iran an attractive haven for illegal miners despite the power crisis.

The problem is compounded by Iran's status as the cheapest place globally to mine cryptocurrency. Electricity costs miners only $1,324 per Bitcoin, according to late 2025 reports, creating a powerful financial incentive for illegal operations. Blockchain analytics firm Elliptic has determined that Iran accounts for 4.5% of all Bitcoin mining worldwide, a significant share for a nation facing severe energy constraints.

How Does Bitcoin Mining Consume So Much Energy?

Bitcoin mining is extraordinarily energy-intensive. Mining companies may consume up to 155,000 kilowatt-hours (kWh) of electricity to mine a single Bitcoin, while the average energy consumed for one Bitcoin transaction is 851.77 kWh, equivalent to nearly a month of power consumption in an average U.S. household. This explains why Iran's power grid is buckling under the weight of hundreds of thousands of mining devices operating simultaneously.

The government has blamed illegal miners directly for the nation's power shortages. A November 2025 report from an Iranian official claimed that local power producers won't be able to meet a third of the country's power demand in 2026, forcing several provinces, including Tehran, to shut down government office operations.

What's Driving Iran's Reliance on Cryptocurrency?

Iran's embrace of digital currency, both legal and illegal, stems from decades of international sanctions and recent geopolitical turmoil. The U.S. and Iran were in active military conflict as recently as February 2026, and Iran has continued restricting access to the Strait of Hormuz for countries perceived as supporting the United States. The country has been using digital currencies as payment rails to avoid sanctions and maintain economic activity.

In 2025, Iran's digital asset ecosystem reached over $7.78 billion, according to blockchain analysis firm Chainalysis. This growth corresponds to major domestic and geopolitical events, including the Kerman bombings in January 2024, Iran's missile strikes against Israel in October 2024, and the 12-day Iran-Israel war in June 2025. For Iranian citizens facing inflation rates of 40-50%, cryptocurrency represents both a sanctions workaround and a way to opt out of a failing economic system.

The U.S. has intensified pressure on Iran's crypto ecosystem. Last week, the Treasury Department sanctioned Nobitex, Iran's largest digital currency exchange, along with three other Iranian digital asset exchanges. The U.S. government accused Nobitex of facilitating the processing of hundreds of millions of dollars for Iran's central bank and the Islamic Revolutionary Guard Corps. Additionally, U.S. Treasury Secretary Scott Bessent revealed the seizure of $1 billion in Iranian assets from various digital asset wallets as part of Operation Economic Fury, launched in spring 2026 by Defense Secretary Pete Hegseth.

How to Understand Iran's Mining Crackdown Strategy

• Reward System: Iranian authorities are offering financial incentives for citizens to report illegal mining operations, creating a crowdsourced enforcement mechanism to identify hidden farms.
• Disguise Detection: Officials are targeting mining farms disguised as legitimate industrial operations that exploit subsidized energy meant for other industries.
• Power Grid Protection: The government is prioritizing the shutdown of the 95% of mining devices operating without authorization to preserve electricity for essential services and prevent rolling blackouts.

The crackdown reflects Iran's desperation to stabilize its power grid amid competing pressures. External sanctions and asset seizures have cut off funding for Iran's weapons programs and regional proxy groups, limiting the nation's ability to earn, move, and access money. Simultaneously, the illegal mining industry is consuming electricity that the country can ill afford to lose, creating a domestic energy crisis that threatens government operations and public services.

Iran's situation illustrates a broader tension in global cryptocurrency mining: the technology's energy demands can destabilize national power grids, particularly in countries already facing economic and geopolitical stress. As authorities worldwide grapple with mining's environmental and infrastructure impacts, Iran's aggressive crackdown signals how seriously some governments view the threat to essential services.
