Does anyone else notice how in crypto projects periodically pop up that promise returns of several hundred percent per month? I've long understood — if something sounds too good to be true, then it's definitely not true. And often behind such promises is a simple Ponzi scheme.

Let's figure out what it actually is and why everyone who wants to invest in crypto should know about it. A Ponzi scheme is essentially a financial pyramid disguised as an investment project. The essence is simple: organizers take money from new participants and pay it out as "profit" to old investors. There is no real income. When the influx of new money stops — everything collapses, and most lose everything.

What does it look like in practice? You invest money, receive great interest, think you've caught a wave. But in reality, it's just your own money being paid out from the wallet of the next investor. When there are fewer people to attract — it's game over.

What should you pay attention to so as not to fall for a Ponzi scheme? The first red flag is guaranteed huge income. If a project promises 10-20 percent per day or 300 percent per month, this is not an investment, it's a scam. The second — complete opacity. You don't know where the money comes from, who the founders are, how the mechanics work. The third — the entire focus is on attracting new people. If the project talks about a partner program, levels, structure, and not about the product — this is a clear sign of a pyramid.

There have been many such schemes in crypto. BitConnect in 2018 promised magical trading bots and lost investors hundreds of millions. PlusToken in 2019 looked like a cool DeFi project but turned out to be one of the largest crypto pyramids. And there are many more examples.

How to protect yourself? First, always check the project before investing. Who are the founders? Is there documentation? What do real people's reviews say? Second, forget about easy money — crypto is risk and work. Third, use verified platforms where there is at least some regulation and support. And most importantly — never invest more than you're willing to lose.

Basically, a Ponzi scheme is an old fairy tale dressed in new clothes. Today it's a DeFi project with AI, tomorrow it will be something else. But the essence remains the same. Keep your head in the fridge, not in the clouds, and then crypto will work for you, not for scammers.
