Ponzi Scheme

A Ponzi scheme gets its name from Charles Ponzi, who ran a scam in Boston in 1920 promising investors huge profits from trading international postal reply coupons. The mechanism he used, paying old investors with new investors' money while pretending it came from a legitimate underlying business, is the same structure that resurfaced across crypto markets a century later.

What separates a Ponzi scheme from ordinary fraud is its total dependence on constant growth. The operator has no real trading strategy or protocol revenue generating the promised returns; deposits from newer participants are instead redirected to pay "profits" to earlier ones, creating a convincing track record that fuels word-of-mouth recruitment. The scheme survives only as long as new capital arrives faster than withdrawals are requested. Once growth slows or many investors try to cash out at once, payouts stop and the operation collapses, often with organizers disappearing alongside whatever funds remain.

Crypto's technical complexity and light regulation have made it a favored setting for this fraud. OneCoin, founded by Ruja Ignatova, collected more than four billion dollars from millions of investors worldwide despite never operating a real blockchain. BitConnect ran a lending platform promising fixed daily returns from an undisclosed "trading bot" before collapsing in January 2018, later prompting a 2021 SEC lawsuit alleging 2.4 billion dollars in investor losses. PlusToken defrauded roughly three billion dollars from mostly Asian investors, and its liquidation of stolen Bitcoin holdings was large enough to move the broader market.

• Guaranteed, fixed returns regardless of market conditions
• Heavy emphasis on referral bonuses to recruit new depositors
• Vague or proprietary explanations of how profits are generated
• Resistance, delays, or fees imposed when investors try to withdraw

Unlike a pyramid scheme, where every participant is expected to actively recruit others to earn, a Ponzi scheme is centrally run by a single operator or small group controlling the flow of money, with most investors unaware they are funding earlier payouts rather than real returns.
