- Putting the hardware wallet on the keychain that is your car key is actually a wrong decision made by the holders. So even if we say that you often use it or open it, it is still not right to put it on your car's keychain.
I just hope that the one who gets it will be returned to the real owner, but if the person who gets it also has cryptocurrency, there will be a 50/50 chance of being able to open it, especially if a hacker is the one who gets it.
