On December 22, PANews reported that Binance co-founder CZ stated on the X platform that he recently saw some people receiving cryptocurrency by accepting private keys or hardware wallets. This is a bad idea because the giver still has the right to access that cryptocurrency. It is better to transfer the cryptocurrency to an address that you own, or better yet, just have the giver send it to your own address. Allowing two people to access the same key (or mnemonic phrase) is a bad idea. When these cryptocurrencies are moved (or hacked), it is nearly impossible to prove who moved it (or was hacked).
