An anonymous reader shares a report: Russia will block access to websites of exchanges that offer crypto-currencies such as Bitcoin, Russian Central Bank First Deputy Governor Sergei Shvetsov said on Tuesday. He called them "dubious." Russian financial authorities initially treated any sort of money issued by non-state approved institutions as illegal, saying they could be used to launder money. Later the authorities accepted the globally booming market of crypto-currencies but want to either control the turnover or to limit access to the market "We cannot stand apart. We cannot give direct and easy access to such dubious instruments for retail (investors)," Shvetsov said, referring to households.
