PANews December 22 news, Binance co-founder CZ posted on the X platform that he has recently seen some people receive cryptocurrencies by receiving private keys or hardware wallets. This is a bad idea because the giver still has access to these cryptocurrencies. The cryptocurrencies should be transferred to an address owned by oneself, or better yet, just let the giver send it to an address owned by oneself. It is a bad idea to let two people access the same key (or mnemonic). When these cryptocurrencies are moved (or stolen by hackers), it is almost impossible to prove who moved it (or was hacked).
