Ponzi and Pyramid Schemes
A Ponzi scheme is an investment fraud that pays earlier investors with money from new investors rather than real profits. Pyramid schemes rely on recruits paying in. Both need a constant flow of new money and collapse when it dries up.
Steady, high returns with almost no risk — that's the classic pitch of a Ponzi scheme. In reality there's often no investing at all: old investors are paid with new investors' money until the flow stops. Ponzi and pyramid schemes have cost investors billions, from Charles Ponzi in the 1920s to modern crypto frauds. This entry explains how they work and the red flags.

Ponzi schemes in plain words
Ponzi organisers often promise high returns with little or no risk, but in many schemes the money is never invested.1
With little or no real earnings, Ponzi schemes need a constant flow of new money to survive.1
Ponzi and pyramid schemes both depend on new participants; once new money dries up, they collapse.2
How a Ponzi scheme unfolds, step by step
A too-good pitch
High, steady returns. See Return on Investment.
Early investors get paid
With newer investors' money.
Word spreads
Success stories bring more money. See Fear of Missing Out.
Withdrawals grow
Payouts exceed new inflows.
The scheme collapses
Most investors lose.
Clawbacks and lawsuits
Recovery is slow and partial.
Worked examples
Example 1 — The maths that can't last
UnsustainableA scheme promises 2% a month on $10m but earns nothing.
| Monthly payout | $10m × 2% = $200,000 |
| Yearly payout | $2.4m from new money |
With no real earnings, the scheme must keep attracting new money to pay existing investors.1
Example 2 — Too smooth
Red flagA fund reports +1% every single month for 10 years while markets swing wildly.
| Losing months | 0 out of 120 |
Returns that never vary are a classic red flag for fraud. See Due Diligence.
Example 3 — Collapse
CollapseNew deposits fall to $1m a month while withdrawals reach $5m.
| Monthly shortfall | $4m |
When the flow of new investors dries up, the scheme collapses.2

Ponzi vs pyramid
Beginner
A Ponzi scheme is outright fraud, while some pyramid participants may earn returns — but both depend on a continuing flow of new investors.2
Red flags
Intermediate
High returns with little risk are the common promise; verify registration and how returns are generated.1 See Securities and Exchange Commission.
Why they last
Advanced
Consistent fake returns build trust, and investors who reinvest rarely withdraw, letting schemes grow for years. See Behavioral Finance.
Common mistakes
Trusting steady returns
Real investments fluctuate.
Relying on friends' success
Early payouts are part of the trick.
Skipping registration checks
Verify sellers and products.
Reinvesting "profits"
Paper gains may not exist.
Check your understanding
Test yourself before moving on. Each answer comes with an explanation.
Key points to remember
