Zhang San discovered a business opportunity: the price of USDT varies across different platforms. He found that he could buy U at a price of 7.3 yuan on a certain platform and then saw that he could sell it for 7.4 yuan on another platform. This way, with a cost of 73,000 yuan for 10,000 U, he could make a profit of 1,000 yuan per transaction. If he makes several transactions in a day, earning over ten thousand yuan daily is no longer a dream.

So Zhang San said, let's do it! To gather the capital, he even took a loan of 200,000 yuan from the bank. However, after just a few days, he was judicially frozen. He thought he was onto something, but in reality, it wasn't. This is clearly price manipulation; platforms that offer such large profits with guaranteed returns are mostly money laundering or gambling sites, and the funds involved are dirty and problematic. Why would others sell to you at a 10% higher profit? Why don't they earn it themselves? Don't they know about certain platforms?

Many of these platforms do not have a T+1 restriction, which is why money launderers and gamblers operate there, buying U at high prices. Never chase after small profits, the so-called business opportunities, only to end up on a path of trouble. According to the legal interpretations of aiding and abetting or concealing crimes, it is easy to presume that you knowingly engaged in illegal activities, which can lead to your conviction.
