A Russian national who founded a cryptocurrency exchange that U.S. officials say became a haven for the proceeds of criminal activity, has been arrested, federal officials said on January 18. Anatoly Legkodymov, who lives in China, was arrested on January 17 in Miami on a charge of conducting an unlicensed money-transmitting business.
