For a large CEX like Binance, $5B might just qualify as a hot wallet.
The point of cold wallet is to minimize movements, if there is high frequency of funds moved from a wallet then it is likely can not be called cold any more. Plus CEX in any case still needs to have large buffer of funds on some wallet to support day trading.
