What is the biggest Ponzi scheme in American history?

Ponzi scheme is the name of investment fraud in the financial field, the originator of pyramid schemes, and is used by many illegal pyramid schemes to collect money. This scam was invented by a speculator named Charles Ponzi. Ponzi scheme is also called "robbing Peter to pay Paul" and "empty gloves and white wolves" in China. In short, it is to use the money of new investors to pay interest and short-term returns to old investors, so as to create the illusion of making money and then defraud more investment.

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".
