What was claimed
Indonesian Rupiah has fully collapsed against Bitcoin. This is the fate of every fiat currency.
Our verdict
InaccurateLive price data show 1 BTC equals roughly 1.4–1.5 billion IDR, which is a market exchange rate, not evidence the rupiah has 'fully collapsed'. A collapse would imply loss of functioning currency and market trading, which is not supported by exchange data. Predicting that every fiat currency will inevitably collapse is an unsupported universal claim; historical evidence shows many fiat currencies remain stable for long periods while others have failed, so outcomes vary by policy and context.
