Looking at how various countries' central banks are implementing digital currencies, it becomes clear why issuing a national digital currency sounds easy in theory but is difficult in practice. Venezuela had already begun experimenting with digital assets, but ultimately the results were minimal, with significant gaps in both technological implementation and policy execution — even less reliable than a solution from a professional team. In contrast, El Salvador's Bitcoin strategy, although controversial, is at least clear in its approach and steadfast in execution, giving the entire country's financial exploration a clear direction.

The deeper issue reflected here is that national CBDCs need to overcome multiple obstacles in technology, law, and economics, and any weak link can cause the entire effort to fail. Some countries want to solve financial difficulties through digital currencies, but if infrastructure, talent reserves, and policy support are not in place, they will ultimately only serve as symbolic gestures. The true success stories tell us that issuing a currency is not the goal; building a sustainable financial ecosystem is the key.
