The trade-off between hot wallets and cold wallets is fundamentally a balance between security and convenience:

Hot Wallets: Sacrificing some security for operational efficiency, suitable for high-frequency trading scenarios.

Cold Wallets: Providing the highest level of security at the cost of operational complexity, serving as a 'safe' for long-term asset storage.

Investors can make flexible choices based on asset scale, trading frequency, and risk preference, and it is recommended to adopt a combined strategy of hot and cold wallets to balance security and flexibility.
