Fiat defenders love slapping the Ponzi label on Bitcoin because it's the only attack that sounds credible to people who've never looked at the mechanics. But PoW is the only monetary system where production cost is provably embedded in every unit. Each block is a receipt — joules burned, difficulty met, hash found. You can audit the work without trusting anyone. Compare that to 'real money' where the supply schedule is decided by committee behind closed doors. One of these systems talks nonsense. It's not Bitcoin.
