Poipex's fraud method is to provide digital currency, Line contact information, and then meet at the time to buy Tether between Line and digital currency. The Poipex platform manager provides an electronic wallet and waits for the platform manager to say that the person who has deposited the digital currency takes the cash. When the banknotes left, we only saw the contract, not the real Tether. This kind of fraudulent method of buying digital currency and depositing money requires a very large amount of money. There are bank transfers and clerk files, but digital currency is a cash transaction, which cannot be stopped once. The transaction can be 500,000, 1,000,000, 5,000,000. There is no upper limit. The combination of fraud platforms and gangs and digital currencies is really terrible and will kill many people.
