When staying at a hotel during a business trip, everyone generally automatically connects to free Wi-Fi. As a Web3 professional, I usually bring my laptop when I go out, hoping to handle some work during the trip. As a result, this became the first big mistake I made.

Public Wi-Fi may seem convenient, but it hides risks you can't imagine. In such an open network environment, your transaction records, private key operations, and account information are very easily sniffed. Especially for those holding crypto assets, a single careless action can lead to serious consequences.

So the lesson now is: any operations related to Web3, wallets, or transactions must never be performed on public Wi-Fi. Even simple account checks should be done only after returning to a secure network. VPNs, physical isolation, offline wallets—these are not just for show, they are essential.
