When a national currency loses its foreign exchange utility, it signals deeper economic instability. Iran's rial has depreciated so severely that it no longer functions as a viable medium of exchange in international markets. This kind of currency collapse raises important questions about currency preservation, asset diversification, and why some investors increasingly turn to alternative stores of value like cryptocurrencies. It's a stark reminder of how traditional fiat currencies can lose purchasing power and credibility when faced with prolonged economic pressure. Such events underscore the appeal of decentralized and non-sovereign assets in uncertain economic environments.
