Crypto would only retain its value in such a situation if a significant market system, in real goods, had been developed around it. Meaning you could exchange your crypto for the things you need. (Meaning the seller would have confidence they could do the same.) It seems like this could work, hypothetically, but given the need we have for the currency of our country, it's hard for me to imagine that crypto would hold its value in the face of some kind of massive computer failure.
