In my opinion, I find it quite stupid to store a crypto wallet inside removable media. First of all, it can easily be lost. Second, it will be found by customs if you are traveling. Third, USB media is more brittle than a HDD hard disk and can be corrupted more easily, thereby making it more susceptible to failure and so on so forth.

I don't know why people like to portray cryptocurrency on a pen drive in movies. Or why rich people even bother to give USB sticks with bitcoin wallets in them when they could just broadcast a P2P transaction. It is not logical at all.
