我的投資者人數突飛猛進地成長。每一個滿意的顧客都會自發成為推銷員。事情能這麼順利，都是拜他們所有人的推銷所賜，不是我一人的功勞。我承認是我推了顆小雪球，但是它自己滾成一場雪崩。
—查爾斯．龐茲（龐氏騙局始祖）
“The legion of my investors grew by leaps and bounds. Each satisfied customer became a self-appointed salesman. It was their combined salesmanship, and not my own, that put the thing over. I admit that I started a small snow ball down hill. But it developed into an avalanche by itself.”
—Charles Ponzi, the original Ponzi schemer
