MMM (Ponzi scheme company)
MMM was a Russian company that perpetrated one of the world's largest Ponzi schemes of all time, in the 1990s.[1][2] By different estimates from 5 to 10 million people lost their savings.[3] According to contemporary Western press reports, most investors were aware of the fraudulent nature of the scheme, but still hoped to profit from it by withdrawing money before it collapsed.[4][5]
In 2011, MMM re-opened as "MMM Global".
