What is a Ponzi scheme? And how does one do it?
<|assistant|>
A Ponzi scheme is an investment scam that involves promising high returns with little or no risk. The fraudster entices victims to invest by paying previous investors with funds from new investors, rather than from earnings on the investment itself. This practice is known as a pyramid scheme and is illegal in most countries.
