Russia retained its position as the world's second-largest Bitcoin miner in 2025, generating 26,000 BTC worth $2.2 billion, according to RBC. Despite facing increased electricity costs and regulatory challenges, the country's hash rate surpassed 1 Zh/s. However, mining profitability has declined to $35 per PH/s in December, marking a 45% drop since July. The introduction of a legal framework for mining in November 2024 has encountered issues with equipment legalization and regional energy restrictions. To mitigate costs, miners are increasingly utilizing AI and gas-powered generation. As the EU's MiCA regulation approaches adoption and concerns from the CFT grow, global regulatory changes are expected to impact the industry further.
