Ponzi scheme

今天網路看到一篇文章有提到Ponzi-like的投資，查了一下，原來是個超級大騙子。

The term "Ponzi scheme" is a widely known description of any scam that pays early investors returns from the investments of later investors. He promised clients a 50% profit within 45 days, or 100% profit within 90 days, by buying discounted postal reply coupons in other countries and redeeming them at face value in the United States as a form of arbitrage. Ponzi was probably inspired by the scheme of William F. Miller, a Brooklyn bookkeeper who in 1899 used the same pyramid scheme to take in $1 million.

CNN Larry King今天訪問Trump
Trump: Well, the economy kept him going. Because people were stupid enough or foolish enough to just keep pouring money into his accounts. So, as other people wanted their money, he would take the new money coming in. It was the ultimate Ponzi. They'll probably change the name of Ponzi to Madoff. It was really the ultimate scheme.

簡單的說-----就是用高額的利息來吸引投資者，而利息則是用後來的投資者的資金來支付。
