The rule of the currency trading industry is that the price of U for black money goes up, and the price of U for white money goes down.
You will not be arrested for speculating in currency, but you will be summoned. The most likely reason is that you sold USDT indiscriminately and received the funds involved in the case and were arrested.
It can be said that if your card is frozen because you sold U on the exchange, you take the initiative to submit information to unfreeze it, and then you are willing to refund, you can basically unfreeze the card by yourself.
Except for special circumstances: for example, you hook up with the exchange currency dealer off-site to discuss the price of U and the exchange rate, or the currency dealer does not pay with real name and transfers the first-hand black money of online fraud to you.
For example, if you make too much money and you cannot reasonably explain the legal source of your USDT, then "the man is innocent, but the treasure is guilty".
Not to mention confiscating your funds, you will get an illegal exchange for you. It's not too much to start with a 37-day package. During these 37 days, you will take cold showers every day, eat boiled vegetables, and endure the humiliation of your cellmates masturbating and shooting on your quilt.
You shiver every day, wondering if you can get out. Outside, your family will be desperate and spend money on lawyers. The news of your arrest will spread to your relatives and friends, and even the old people and dogs in your village will know about your arrest.
All this is because you want to sell U at a high price.
Why are other people's U prices high? X can make 3,000 yuan with 10,000 black money, so the loss of giving you U at a high price is basically negligible.
