The essence of the trade-off between hot wallets and cold wallets is the balance between security and convenience:

Hot Wallet: Sacrifices some security for operational efficiency, suitable for high-frequency trading scenarios.

Cold Wallet: Provides the highest level of security at the cost of operational complexity, serving as a "safe" for long-term asset storage.

Investors can flexibly choose based on asset scale, trading frequency, and risk preference, and it is recommended to adopt a combination of hot and cold strategies to balance security and flexibility.
