According to ChainCatcher news, as reported by Yunnan Legal Daily, in February 2023, seven defendants jointly discussed building an online platform for investing in virtual currency. After reaching an agreement, they contacted a company in Sichuan, where technicians developed the "3M platform" to issue the token "Mavro Coin," enticing investors to join the project with the promise of high profits from virtual currency investments. Once the platform was established and operational, the seven defendants actively promoted the investment platform's potential for high returns and conducted offline promotions to recruit subordinates, who in turn recruited others. According to the assessment, there were a total of 375 users whose subordinate levels were three or more (including three levels), and the total number of subordinates was 30 or more (including 30). The seven defendants profited between 4,300 yuan and 20,000 yuan.After hearing the case, the Xichou County People's Court found that the seven defendants used the "3M platform" to issue virtual currency, enticing investors to join the platform with the promise of high profits from virtual currency investments, and organized hierarchical structures in a certain order, developing personnel numbers as a means of profit. Their actions constituted the crime of organizing and leading pyramid selling activities. Based on the defendants' roles in the crime, the levels of development, their confessions and acceptance of punishment, and the return of embezzled funds, they were sentenced to fixed-term imprisonment ranging from two years and six months to one year and six months, with probation applied, and were fined.
