I believe this is a scam. I had assets worth over 8000 USDT and a profit of 5000 USDT. When I attempted to withdraw a large amount, my account was suddenly frozen. They accused me of conducting illegal transactions with an unknown account. They have created unnecessary rules with numerous restrictions. To unfreeze my account, I am required to add an amount equal to 100% of the total principal in the account. They even threatened to seize my properties and damage my personal reputation. I now realize that I have been scammed by them and have lost my money.
