Russian authorities charge BitRiver founder Igor Runets with alleged fraud related to a crypto mining equipment contract, according to multiple reports. CoinDesk says the case centers on accusations that Runets fails to deliver on a contract and notes that he is transferred from house arrest to a pre-trial detention facility. Cointelegraph reports that the alleged fraud involves a deal for crypto mining equipment described as worth about $8 million, and it ties the matter to a business relationship involving Russian billionaire Oleg Deripaska. The articles describe different figures for the alleged amount, with one outlet citing $12.5 million and the other citing $8 million, but both characterize the allegation as non-delivery or failure to carry out terms of a mining-related agreement. Both sources also indicate that the charges are being pursued by Russian authorities and that Runets faces pre-trial restrictions while the case proceeds. The reports do not provide details on any court outcome or adjudication at this stage.
