The most volatile aspect of crypto is the the backbone. Power and network infrastructure.

I don't know many people that expect those to hold up when everything comes tumbling down.

Once we are all "offline", the only true value is barter for goods.

Ammo, food, water, silver and gold, etc. Crypto is as good as a 10K dollar bill when it's all hand to mouth and shooting those that want to take everything you(physically) have.
