Your talking in theatricals. It is kinda non-sense your computer has chips.. your printer has chips.. are they all set with backdoor? You can go on and on with it.... at end of day there has not been a hardware wallet with a backdoor (to my knowledge). Can you point to so meting that shows a modern hardware wallet with a security flaw this big? Do you have anything hard proof not theoretical? And which hardware wallets have you used?
And I'm not saying paper does not have a place if your planning on leaving it cold for long period of time and not using it, if done right paper is great. I just don't like to use you have to import into wallet. On hardware I like that if you need use it signs transactions on the device huge pro if you need to access it. But if you are putting it away for the next year or so paper wallet is great for you.
theoreticals* and hardware hacking is not theory, its been done just not in the Bitcoin space yet... as far as we know.
Right but which is more likely to have Bitcoin stealing malware, a chip in a Dell PC or a chip in a device designed to store bitcoins? I would think that the hardware wallets are the ones most likely to be targeted by this sort of thing. Also hardware wallets are much simpler devices which makes this sort of thing a bit easier.
If there was a hardware wallet with a backdoor it would be unlikely anyone would have found it. I don't think there are many publicly known techniques for detecting this sort of thing other than dipping the chip in acid and using an electron microscope. Certainly there have been many Bitcoins stolen from hardware wallets where the owners claim not to know why but its more likely those thefts were due to user error rather than a backdoor. What is certain is that hackers will try this as there are many hackers out there capable of these kinds of attacks and the incentive is definitely there. You must trust the manufacturer of any computer you use to store Bitcoins, whether it be a general purpose PC or a hardware wallet. If you use a hardware wallet you are still putting significant trust into the hands of the manufacturer and anyone who tries to say otherwise is completely wrong.
