PARIS – A Russian bitcoin expert at the center of a multi-country legal tussle was sentenced in Paris on Monday to five years in prison for money laundering and ordered to pay 100,000 euros (more than $120,000) in fines in a case of suspected cryptocurrency fraud. A court acquitted Alexander Vinnik of charges of extortion and association with a criminal enterprise, according to his lawyers. He was accused of being behind a 135 million-euro ($160 million) fraud campaign that used ransomware and the cryptocurrency bitcoin. French prosecutors say Vinnik was one of the creators of a malicious software called “Locky” that was delivered through email. If downloaded, the recipient’s data was encrypted and they were asked to pay ransom in bitcoin to free it.
