I wonder: Would a Trezor survive liquid nitrogen?
Half-jokingly...USB connector tech has to survive too, which is not likely.
Maybe you can use a microscope to get the info, though.
Here is something regarding 11th century (and nearby) tech.
https://en.wikipedia.org/wiki/Medieval_technologyWell, interestingly enough, wheelbarrow was invented back then (in 12th century).
This is not quite 100% a joke: If you really believe Bitcoin is the shit, and it will be worth more later then there is a certain logic with dying with some, then being revived later, remembering your passphrase from long term memory, and having the whole money thing taken care of.
12th century paper and such is quite readable even now, as are long dead languages. It's not impossible to read an 8 inch floppy or a 1950's era core memory you just have to build an interface (trivial with something like a Raspberry Pi and a set of amplifiers). Maybe Cryptosteel anded with a code you memorize. Or a Cryptosteel that decrypts a Trezor wallet that is protected with a passphrase. Might be too easy to hack. Then again in 100 years a Trezor
s physical security would probably be trivial as well.
Hm. Do I really want to dunk my head in a tank of liquid nitrogen?
There might be some reasons to want to secure your bitcoin beyond one or two generations, but I think that it is better to discontinue with your scenarios about being able to come back in a future life... that's fucking ridiculous. We have to be more practical in terms of our own finite lives and our financial and psychological plannings around our inevitable deaths... there are way the fuck more chances for life extension than being able to come back and even life extensions are likely not going to give you a whole hell of a lot of time. So more practical is just to think of how you are going to spend your bitcoins while you are still alive and the extent to which you might want to pass some of them down.. Of course, you lose a decent amount of control when you pass down, and trusts that you control can usually only go a bit beyond the measurement of any life in being at the time that you create the trust... within the vast majority of common law rules against perpetuities principles.
