Zhimin Qian, 47, tricked over 128,000 people in China and converted their money into Bitcoin.
Qian, also called Yadi Zhang, admitted in Southwark Crown Court to illegally acquiring and holding cryptocurrency.
She fled China using fake documents and entered the UK, planning to launder her stolen funds through property purchases in 2018.
Global Investigation and Seizure
The Metropolitan Police conducted a seven-year investigation into her worldwide money laundering network.
Officers seized 61,000 Bitcoins from Qian, marking one of the largest cryptocurrency confiscations globally.
Will Lyne, head of economic and cybercrime command, described the case as one of the biggest money laundering cases in UK history.
Legal Action and Warnings
Courts previously jailed 43-year-old Jian Wen for six years and eight months for assisting in the fraud.
Authorities will sentence Qian at a later date following her guilty plea.
Robin Weyell, deputy chief crown prosecutor, warned criminals exploit cryptocurrencies to hide and move assets.
She emphasized that the CPS will block fraudsters from regaining stolen assets through criminal and civil actions.
