In a collapsed human civilization, Bitcoin’s viability as a settlement layer hinges on its decentralized, trustless nature. With no central authority, its blockchain could persist on surviving nodes, provided electricity and internet remain. Bitcoin’s fixed supply ensures scarcity, potentially replacing barter systems with a verifiable digital currency. Miners, incentivized by transaction fees, could maintain the network using renewable energy sources like solar or wind. However, challenges include network fragmentation, hardware degradation, and reliance on specialized equipment. Pre-existing wealth disparities could worsen, and volatility might hinder adoption. Still, Bitcoin’s cryptographic security and global recognition make it a plausible medium for trade and value storage in a post-apocalyptic world, assuming technological infrastructure endures.
