Points of Focus

• BitRiver founder Igor Runets has been placed under house arrest on tax evasion charges as courts open bankruptcy supervision tied to the miner’s controlling shareholder.
• The case centers on unpaid equipment claims and mounting energy debts, compounding pressure from US sanctions imposed in 2022.
• The collapse risk signals a turning point for Russia’s industrial Bitcoin mining model, long built on cheap power and scale.

Russia’s biggest industrial Bitcoin miner is unraveling on two fronts at once. Igor Runets, the founder of BitRiver, was placed under house arrest on tax evasion charges, according to court records cited by Russian media. 

Days later, a regional arbitration court opened bankruptcy supervision against Fox Group, the holding company that controls 98% of BitRiver. The overlap is not a coincidence, exposing how legal risk, energy dependence, and sanctions collide when a mining firm loses access to capital and trust.

Igor Runets, founder and CEO of crypto mining firm BitRiver, was detained on January 30 over allegations of hiding assets to evade taxes.

A Moscow court ordered him under house arrest starting January 31, with an appeal window open until February 4.

Arrest adds pressure to a strained balance sheet

Runets, 39, faces multiple counts for allegedly concealing assets to evade taxes and has only a narrow window to appeal before the order is fully enforced, according to Russian court reporting. The detention comes as BitRiver’s finances are already under court scrutiny. In January 2026, the Arbitration Court of Sverdlovsk Oblast opened bankruptcy observation after a claim by Infrastructure of Siberia, an affiliate of EN+ Group, over roughly $9.2 million in prepaid mining equipment that was never delivered. Enforcement proceedings failed to recover assets, filings show.

From national champion to frozen accounts

BitRiver once operated 15 data centers with 533 megawatts of capacity and more than 175,000 servers, a footprint that at peak controlled over half of Russia’s industrial mining market. That scale relied on uninterrupted power contracts and imported hardware, both of which became fragile after April 2022, when the US Treasury’s Office of Foreign Assets Control sanctioned BitRiver, marking the first time Washington targeted a crypto mining company. Sanctions narrowed equipment access and client relationships, while court-ordered account freezes tied to the insolvency case now threaten day-to-day operations.

Local reporting adds detail. Power suppliers, including Rosseti Siberia, have sought recovery of unpaid electricity bills tied to 2024 service agreements. Several facilities have reportedly shut amid regional mining bans. Senior managers have departed, and court notices to company addresses have gone unclaimed. These are not cosmetic issues but signs of a firm struggling to meet basic legal and operational obligations.

Why this matters for Russia’s mining model

The timing matters, because Moscow loosened crypto rules in 2024 to keep trade moving under sanctions, and large miners were expected to benefit. BitRiver’s distress points to the opposite outcome once energy debts mount and equipment disputes freeze cash. Post-halving economics add pressure, as rewards were cut in 2024, margins tightened, and miners globally pivoted toward AI and data hosting. BitRiver’s problems show how hard that pivot becomes when accounts are frozen and ownership is contested.

What comes next

If bankruptcy supervision deepens, forced asset sales or a change in ownership are likely. Analysts cited by Kommersant warn this could accelerate consolidation across Russia’s mining sector, favoring players with cleaner power contracts and sanction-resilient supply chains. For readers watching Russia’s crypto economy, the question is blunt: can industrial mining survive without stable energy terms and legal certainty? BitRiver’s case suggests scale alone is no longer enough.
