LONDON - Crypto giant Binance processed almost US$346 million (S$457 million) in Bitcoin for the Bitzlato digital currency exchange, whose founder was arrested by United States authorities last week for allegedly running a “money laundering engine,” blockchain data seen by Reuters show.

The Justice Department on Jan 18 said it charged Bitzlato’s co-founder and majority shareholder Anatoly Legkodymov, a Russian national living in China, with operating an unlicensed money exchange business that “fueled a high-tech axis of cryptocrime” by processing US$700 million in illicit funds.
