If you find that your exchanges like Certain Easy, Certain Safe, etc. have restricted withdrawals, the common reasons are the following three:

First, the exchanges themselves are mainstream centralized exchanges with risk control and anti-money laundering systems, which monitor and identify the addresses involved in coin transfers. If the outgoing and incoming addresses are flagged as involved in gambling or money laundering, the exchange will implement risk control measures on your account and ask you to explain the situation. The restrictions imposed by exchanges are becoming increasingly stringent.

The second reason is that the exchange account has been judicially frozen by domestic public security agencies. Although the exchanges are all overseas, they will cooperate with domestic public security for freezing. As long as relevant procedures are submitted in the law enforcement request section on the exchange's official website, the exchange account can be frozen. For example, if you receive funds related to fraud, the public security agency will issue a letter to the exchange for cooperation in freezing the account, or if your account receives USDT from a gambling address, your account will need to be frozen.

The third reason involves foreign judicial freezes, such as those from the US or India. In addition to the reasons mentioned, aside from fraud and flagged addresses, it could also be due to regulations regarding U in the Middle East.
