The essence of currency is not that it is issued by a country, nor that a country has faith in it, but whether the market is willing to believe in it long-term. And the core of "belief" is not slogans, not GDP, not skyscrapers, but the first fundamental logic: can you use it freely? Because currency is never just numbers; it is the control over wealth. Whether you can withdraw it at any time, exchange freely, and move it freely determines whether it is truly your asset or just a string of numbers temporarily held by someone else. True currency trust is not about appearing stable during normal times, but about being able to freely control your wealth even when risks arise. So, is the money in your bank really completely yours?
