Qian Zhimin, the main culprit in a money laundering case involving 60,000 BTC, purchased a total of 194,951 BTC between 2014 and 2017.

According to a report by Caixin on November 16th, as reported by Mars Finance, between 2014 and 2017, Qian Zhimin, using the name of Lantian Gerui, launched ten "zero-risk, high-return" "financial products," including "Lantian No. 1," "Lantian No. 2," and "Youli Youbi." He used promotional meetings and a pyramid scheme-like approach to recruit members, enticing the public to invest with high interest rates. Over approximately four years, he illegally raised over 40 billion yuan, affecting nearly 130,000 people. Of this, 34 billion yuan was used to pay out returns on earlier products, while billions more were siphoned off for Qian Zhimin and his accomplices, with a large portion used by Qian Zhimin to purchase cryptocurrencies. According to a British court, in June 2014, Qian Zhimin instructed his "front man" to open an account for himself on the cryptocurrency exchange Huobi, using 180 million yuan of investor funds to purchase 100,250 Bitcoins; subsequently, the account held 143,951 Bitcoins. Between January and June 2017, she purchased 51,000 Bitcoins through over-the-counter (OTC) transactions with 468 million yuan in investor funds. This brought her total holdings to 194,951 Bitcoins. Qian Zhimin's defense lawyer stated that she first learned about Bitcoin in 2012, and that her ambition was to one day hold 210,000 Bitcoins, representing 1% of the total Bitcoin supply. She nearly achieved this goal. The defense lawyer also claimed that Qian Zhimin's average purchase price of Bitcoin on Huobi was 2,815 yuan per coin (statistical method unknown). By the time of her sentencing in the UK, the price of Bitcoin had increased 266 times to 750,000 yuan per coin.
