What is a Ponzi scheme?

Imagine someone collecting money from a group of friends, promising steady profits from a “secret strategy.” Instead of investing it as they claim, they use the deposits of later participants to pay the first ones. The first participants see money in their accounts, become convinced the strategy works and often recommend it to friends.

That is how a Ponzi scheme works: new inflows are presented as investment profits. When not enough new money comes in, or many people ask to withdraw at the same time, the scheme can’t keep up. The balance an app displays may be nothing more than a number on a screen.

In crypto, the story can be dressed up with terms such as staking, automated trading or mining. These activities are not scams in themselves. The question is whether they actually take place and where the payouts come from.

Why it matters

A successful withdrawal doesn’t prove that a service is trustworthy. The early payouts are precisely what helps build trust. The same goes for testimonials from people you know: someone may really have been paid without knowing that the money came from later victims.

We find the question “who is paying this return, and why?” more useful than any impressive presentation. Using a blockchain or a smart contract doesn’t automatically make the business model sustainable or honest.

What to watch out for

Guaranteed high returns, vague explanations of where income comes from, pressure to deposit quickly and obstacles to withdrawals are serious warning signs. None of them alone is enough to call something a Ponzi scheme, but you need to be careful when they appear together.

A Ponzi scheme is often confused with a pyramid scheme. In a pyramid scheme, the financial incentive rests mainly on recruiting new members. In a Ponzi scheme, the organizer usually presents a supposed investment and manages the payouts. The two models can coexist, but not every failed project or price drop is a Ponzi scheme.
