Delayed update
The platform was suddenly frozen and could not be bought or sold. When the platform resumed trading, it was found that its investment funds were stolen. In fact, after the "black platform" freezes the customer account, the trader will operate the disk. When customers buy up, the disk will be pulled down, and when customers buy down, they will be pulled up, so customers are doomed to lose money.
Traders cheat.
In fact, the K-line charts on these futures platforms can be drawn by traders. As long as the final price is consistent with the regular futures market, many investors do not know that the K-line on the disk has been tampered with.
Using virtual funds
Heizhuang gambles with retail investors with virtual funds. These fake trading platforms are actually a closed casino, because the trading leverage of "Heizhuang" is much higher than that of retail investors, who are doomed to lose money.
