CZ wrote an article titled "Protecting Your Cryptocurrency SAFU" on Binance Square, which mentioned:
In terms of using mobile phones, CZ recommends using iPhone. If you know more about technology, it is recommended to use Android mobile phones equipped with GrapheneOS. It is recommended to use only one mobile phone to install the wallet. Don't mix it with mobile phones in daily use. The mobile phone should only install wallet software, not install anything else. In addition to using the wallet to transfer money, you should always put the mobile phone in flight mode. It is also recommended to use a separate SIM card for the mobile phone, and only use 5G to connect to the Internet, not connect to any WiFi.
In terms of email, CZ suggests using Gmail or ProtonMail and setting up a unique email account for each exchange used, so that it is difficult to guess. If there is a problem with another exchange, Binance accounts will not be affected and the number of phishing or targeted email scams received will be reduced.
