#数字货币市场洞察 The crypto world is a complex and ever-changing ecosystem, with stories of scams, fraud, and criminals preying on each other happening all the time. The ironic part is—those who are skilled at scheming often end up falling into traps set by their own kind. Today, let's take a look at some real-life cases where criminals turned on each other and see what happened to them in the end.

**Money Launderers Get Double-Crossed**

In earlier years, some criminals would use dirty money to buy USDT, causing trouble for many sellers who needed to cash out—their bank cards would be frozen and their funds stuck. It seemed like these money launderers had the upper hand, but not so fast. Some groups figured out their methods and posed as regular buyers, approaching them proactively and acting very straightforward during transactions. The money launderers, thinking they had an easy deal, would transfer the crypto—only for the "buyers" to disappear without paying a cent. The bitterest part? The money launderers couldn’t go to the police since their funds weren’t clean in the first place, and could only watch their crypto vanish. That’s what happens when you try to profit from crime.

**The PolyNetwork Hacker’s Dilemma**

In 2021, a hacker stole over $600 million worth of assets from PolyNetwork. Instead of laying low, the hacker openly mocked the platform’s security flaws in public, acting extremely arrogant. But he seriously underestimated the industry's collaborative power. Almost overnight, all major exchanges worked together to completely block the hacker’s addresses, freezing even the stolen USDT. Want to spend the money? No way. With $600 million burning a hole in his pocket and nowhere to go, the hacker had no choice but to give up and return everything. The lesson? The cost of crime is much higher than you think.

**Small Exchange Implodes from Infighting**

Some sketchy small exchanges are set up from day one with a plan: run off with user funds once they’ve collected enough. To cover their tracks, they even plan to claim they were hacked. Sounds foolproof, but human greed ruins even the best-laid plans. When it came time to split the loot, internal members fought over how much each deserved. One person, feeling shortchanged and angry, reported the entire scam to the police. The result? The whole team was busted and all illegal gains were confiscated. Ironic, isn’t it? That one bout of infighting turned "scammers about to succeed" into convicted criminals.

**Young People Selling Bank Cards**

There’s also a group who try to make quick money by selling their own bank cards to money laundering gangs. The idea is to earn easy cash, but it’s playing with fire. After using the cards to move funds, the gangs disappear without paying a cent of the promised reward. These young people not only make no money but end up facing legal consequences for assisting cybercrime, with a bleak future ahead. It’s a classic case of "losing both the bride and the army."

**Conclusion**

Chaos definitely exists in crypto, but the bigger truth is—there are basically no winners when you try to profit through shady means in this ecosystem. Whether you’re a money launderer, scammer, or "smart guy," the long arm of the law will catch up to you eventually. Every failed case serves as a warning: there’s no such thing as a free lunch, and in the world of criminals preying on each other, there are never any lasting winners.
