Qian Zhimin, also known as Zhang Yadi, has pleaded guilty in Southwark Crown Court, UK, for her involvement in a Bitcoin fraud exceeding £5.5 billion ($7.4 billion). This case marks the largest cryptocurrency seizure globally. Between 2014 and 2017, Qian defrauded over 128,000 individuals in China, converting the funds into Bitcoin and fleeing to the UK to launder money through real estate. The Metropolitan Police highlighted the seven-year investigation, which involved international law enforcement collaboration. Her accomplice, Wen Jian, was sentenced to six years and eight months last year. Qian is currently in custody awaiting sentencing.
