Why do you need to use a hardware wallet like the NANO LEDGER to transfer money from one person to the next, when you can simply transfer it from one Bitcoin address to the next? A hardware wallet will draw attention from customs, like we have seen before, when custom officials strip searched a person for wearing a Bitcoin t-shirt.   

Bitcoin is definitely not all about criminals and secret government agencies, like it is being portrait in movies and the media. A lot of people are using it for legitimate business and legal trading on regulated exchanges.
