The point of having dormant money in a CEX deposit is to provide customers with the ability to store their funds securely and access them whenever they need to. This allows customers to have peace of mind that their funds are safe and accessible when they need them. Additionally, it allows CEXs to provide customers with a wide range of services, such as trading, lending, and margin trading. However, it is important to be aware of the risks associated with leaving money in a CEX deposit for an extended period of time. The value of the funds may depreciate over time due to market volatility, and the funds may be subject to theft or fraud if the CEX is not adequately secured. Therefore, it is important to weigh the benefits and risks associated with leaving money in a CEX deposit, and to withdraw funds if it is deemed too risky.
