A Chinese national has been convicted following an international fraud investigation which resulted in what's believed to be the single largest cryptocurrency seizure in the world. The Metropolitan Police say it recovered 61,000 bitcoins worth more than $6.7bn in current prices. Zhimin Qian, also known as Yadi Zhang, pleaded guilty on Monday at Southwark Crown Court to illegally acquiring and possessing cryptocurrency. A second person appeared in court on Tuesday to admit to their role in the scheme. Malaysian national Seng Hok Ling, of Matlock, Derbyshire, pleaded guilty at Southwark Crown Court of entering into a money laundering arrangement on or before 23 April 2024. Qian had help from a Chinese takeaway worker named Jian Wen, who was jailed for six years and eight months last year for her part in the criminal operation.
