Bitcoin (or crytos, more generally) require: - Abundant power - Hightech personal electronics - Electronics manufacturing - Global and reliable networking - Education to understand it all Remove any one of those, and i think it wont work. Now there are different kinds of apocalypses, here are some thoughts: - It's a fair bet that electronics cannot be really manufactured in any kind of scale, and most current consumer electronics are not especially long lived. Give a decade, and most people will not have the gear to run Bitcoin. - If you have Abundant power, i would use it grow potatoes in greenhouses, or similar, not for crypto mining. - How would the global networking, or even local, survive the apocalypse? Given that is needed for the blockchain to sync, it seems it will stop working more-or less immediately, or worse, fork. - Which brings me to, how would people agree on which blockchain, or fork of bitcoin to use? - And most of all, if modern education systems fail also, how would anybody understand any of this anyway? On the other hand, everybody understands potatoes. Boil em, mash em, stick em in a stew. Now that is the currency of the apocalypse!
