The CONCEPT of ST refers to the trading pair list of currencies with ST identification, that is, the exchange will carry out ST treatment (special treatment rule). It indicates that the project party has abnormal behaviors such as inability to continue development, serious damage to the community, manipulation of market price, insufficient currency trading volume, etc., and the platform will conduct ST treatment on such behaviors, thus informing users of risks. Generally speaking, the transaction pairs of tokens are processed by ST, which means that the token has the risk of delisting, but it does not mean that the token has no value. Once the fundamentals turn good and the project eliminates abnormal conditions, it may bring rich returns to investors. In general, ST tokens tend to be very risky, and ordinary investors are advised to invest cautiously.
