Russia has emerged as the world’s third largest bitcoin miner, with its share in the total computing power of miners – known as the ‘hash rate’ – reaching 11.23%, data from the University of Cambridge published this week shows.

Russia’s share in bitcoin mining grew by nearly 30% from last year’s figures. The United States is still in the lead with 35.4%, and second place is held by Kazakhstan with 18.1%. While the media embraced and paraded the news of the US becoming the globe’s leading mining hub, Russia’s ascendance went largely unnoticed.

Bitcoin miners were forced to scatter around the globe after China imposed a sweeping ban on the crypto-mining industry in late May amid a large-scale crackdown on cryptocurrency use in the country. Prior to that, China was the largest mining center for bitcoin, with 75% of bitcoins mined on its territory in 2019, then dropping to around 50% in 2020 and 44% in May. After the ban came into force, China’s hash rate fell to zero by July.

Russia’s relatively low energy costs and cool climate in the Far Eastern regions appear to draw miners and even let companies using surplus electricity to benefit from bitcoin‘s surging prices earlier this year. However, concerns have been raised regarding illegal mining.

In a letter to the government’s energy department in late September Igor Kobzev, governor of Russia’s Irkutsk region, complained about “avalanche-like growth” of energy tariffs, putting the blame on underground crypto-miners.
