The future of money might not be what we think. Some industry leaders argue that currency systems will eventually pivot toward a foundation based on productive work and energy consumption—a concept that resonates remarkably well with how Bitcoin's proof-of-work model operates. This framework suggests a shift away from traditional fiat systems toward assets backed by tangible economic activity rather than institutional trust alone. The alignment between this vision and Bitcoin's energy-intensive validation mechanism raises interesting questions about how next-generation financial systems could function. Whether energy-backed currencies become mainstream remains to be seen, but the logic behind it certainly challenges conventional thinking about monetary value.
