According to the Legal Daily, Beijing police recently cracked down on a group that organized and led pyramid schemes in the name of investing in virtual collections. The case involved more than 100 pyramid scheme participants and more than 2.8 million US dollars. The pyramid scheme introduced the "rules of the game" to the public through on-site lectures and WeChat group messages. In the name of investing in virtual collections, it attracted unspecified objects to recharge and purchase, earning profits from it, causing property losses to many people. The police reminded that some criminals turned "digital collections" and "virtual currencies" into their own "wealth codes", and used digital economic concepts and technologies as a cover to engage in illegal fundraising and other criminal activities.
