#加密货币安全事件 It seems CZ is also paying more and more attention to the security of hardware wallets. He said that private keys must never leave the device, and I quite agree with this view. After all, the private key is our "lifeline"; once it is leaked, it could be a big problem. But to be fair, with such strict requirements, can ordinary users really do it? It still depends on wallet manufacturers to put effort into technology and achieve the utmost security. When everyone uses hardware wallets, they should also be more cautious and not be too casual.
