Zhimin Qian, a Chinese national, has pleaded guilty at London's Southwark Crown Court to charges related to the possession of 61,000 bitcoins, valued at approximately $6.75 billion. This case marks the largest cryptocurrency seizure in history. Qian was involved in defrauding over 128,000 victims in China, amassing around 5 billion pounds through investment fraud between 2014 and 2017. She converted the illicit funds into Bitcoin and fled to the UK in 2017 to launder the money. British authorities began investigating in 2018, leading to the seizure of a digital wallet containing the 61,000 bitcoins. Qian and her accomplices are set to be sentenced on November 10, 2025.
