SlowMist Cosine forwarded a security case about the use of a hardware wallet on the X platform: "A user stored BTC in a hardware wallet and thought they could rest assured. After a few years, they took it out and found that the battery was bulging and couldn't be used anymore. They found the same wallet and went to Huaqiangbei to replace the battery. However, when they opened it, they found that the wallet had already been initialized and there was no backup, and it was forever lost. We remind everyone that they must also make a backup when using a hardware wallet. If they need to repair a hardware wallet, they must also find a professional hardware team." Cosine commented on this: "After a few years, the battery bulging can no longer be used, but the wallet has already been initialized. Which hardware wallet, we can avoid pitfalls...
