Is there any danger in travelling internationally with a hard wallet? I am not afraid of confiscation, because it can be recovered with the passphrase, but what about the chance of them denying you entry into the country because you have an evil cryptocurrency hard wallet on you? Could I buy a hard wallet in my country, transfer crypto to it, then leave it behind in a safe place, then buy another same hard wallet in another country and using my passphrase get access to my crypto again?
