Igor Runets, the founder and CEO of BitRiver, just went from house arrest to a jail cell. A Moscow court ordered his formal detention on July 22, upgrading his pretrial custody after prosecutors tacked on new fraud charges involving nearly 1 billion rubles, roughly $13 million, related to the alleged supply of mining equipment to entities connected to the En+ Group.

Runets had been under house arrest since January 30, when he was initially picked up on tax evasion charges. The fraud allegations represent a significant escalation, and they land at a moment when BitRiver’s parent company is already circling the drain financially.

From tax evasion to fraud: the charges pile up

The original case against Runets fell under Article 199.2 of the Russian Criminal Code, which deals with concealment of assets to avoid paying taxes. That charge alone carries a potential prison sentence of up to three years.

But the new fraud allegations are a different animal entirely. Prosecutors claim Runets orchestrated a scheme involving mining equipment that was supposedly delivered to structures linked to En+ Group, the Russian energy and metals conglomerate. The alleged damages from that scheme total nearly 1 billion rubles.

The Moscow Zamoskvoretsky District Court approved his detention for two months while investigators dig deeper.

BitRiver’s parent entity, Fox Group of Companies LLC, entered bankruptcy monitoring around January 27, just days before Runets was first detained. The company reportedly owed debts exceeding $9 million, linked to the same equipment delivery disputes that now form the basis of the fraud case.

BitRiver’s rise and the sanctions shadow

Founded in 2017, BitRiver grew into a genuine heavyweight in global crypto mining infrastructure. The company operates 15 data centers across Russia with a combined capacity of 533 MW and more than 175,000 servers. BitRiver reported revenue exceeding 10 billion rubles in 2024, making it not just Russia’s largest mining operation but one of the biggest in the world.

That growth trajectory hit a wall in April 2022 when the US Treasury Department imposed sanctions on BitRiver, marking the first time Washington had sanctioned a crypto mining company. The sanctions were part of broader measures targeting Russian entities following the invasion of Ukraine, and they complicated BitRiver’s ability to do business with international partners and equipment suppliers.

What this means for crypto mining and investors

Moscow passed legislation in late 2024 that gave mining a legal foundation in the country. Runets was, in many ways, the poster child for that effort. Having your industry’s most prominent figure detained on fraud charges is not exactly a vote of confidence in the regulatory environment.

The bankruptcy monitoring of Fox Group also raises questions about counterparty risk for any clients who were hosting mining operations through BitRiver’s facilities. If those data centers change hands or go dark during bankruptcy proceedings, hosted miners could face downtime, relocation costs, or worse.
