Recently, I noticed that more and more proposals promising incredible returns are appearing on social media and messaging apps. This made me remember the Ponzi scheme — one of the oldest and most insidious scams in financial history. Interestingly, people still fall for these tricks even though the mechanism has been known for hundreds of years.

It all started with Italian Carlo Ponzi, who in the 1920s in Boston orchestrated one of the most notorious scams. He convinced people to invest in postage stamps, promising to sell them at a higher price than the market value. In reality, there were no stamps — he simply took money from new investors and paid "profits" to earlier ones. People saw real payouts and recommended the scheme to friends. This created the illusion of profitability. Since then, such scams have been named after him, and the Ponzi scheme has become a generic term for all similar frauds.

How does it work? First, they attract initial investors with loud promises of high returns. Then, they use the money from newcomers to pay dividends to early participants — creating the impression of a functioning system. Participants are encouraged to recruit more people for a commission. The pyramid grows, but only up to a certain point. When there are not enough new investors, everything collapses. The last in line lose all their money. History has many such cases — just think of Bernie Madoff’s scam, which defrauded investors of billions.

How to recognize something like this? The first sign is promises of high income with minimal risk. If it sounds too good to be true, it probably is. The second sign is vague explanations of how exactly profits are generated. The third is pressure to make quick decisions and recruit new people. The fourth is difficulty withdrawing money. If I see several of these signs at once, it’s almost certainly a Ponzi scheme or something similar.

How to protect yourself? The main thing is education. You need to understand how investments actually work. Before investing, thoroughly research the company, its team, and its products. Check its reputation and look for reviews from independent sources. Never invest money you can’t afford to lose. And most importantly, don’t succumb to pressure to recruit friends and acquaintances. That’s a sure sign that it’s not an investment but a scam.

If an opportunity looks like a Ponzi scheme, it’s better to walk away immediately. The risk of losing everything simply isn’t worth the dubious profit. Remember, your money is the result of your labor, and it deserves respect and caution when choosing where to invest.
