Charles Ponzi was an Italian-born speculator who lived in the 20th century. 1903 immigrated to the United States. 19 19, he began to plot. The swindler invested in a non-existent enterprise, promising investors a 40% profit return within three months, and then, due to the generous returns of previous investors, Ponzi successfully attracted 30,000 investors within seven months. This conspiracy lasted for a year, and only those who were carried away by interests woke up, and later people called it "Ponzi scheme".
