I just spent over 2200 yuan to buy a Onekey hardware wallet because I didn't bring it with me when I went abroad. I bought three during the Chinese New Year, and with Onekey, I gave away one to my milk brother. I just bought another one. Including Apple phones, Nai Zi Ge has never sold or bought second-hand. The address of the cryptocurrency trading wallet changes from time to time. When it comes to safety issues, one cannot be too careful. Prudence lies in prudence.
