Makes lots of sense. What if my offline device gets broken, or burnt, or w/e? Is there a super safe way to store bitcoins? I'm getting to the idea there is no 100% safe way to do it. My online wallet could get hacked and my offline USB/HD could crack...
Believe that's where the beauty of Trezor and Ledger come into play. If you somehow break or lose these devices or it gets stolen, I think you just need to provide the seed password or pin code to retrieve your full balance onto the replacement device.
