標題：Currency Drain and Its Impact on a Country"s Economy

Currency drain is a common problem in many countries, especially during economic downturns or periods of high inflation. It refers to the outflow of capital from a country, usually due to investors seeking higher returns in other countries or due to uncertainty caused by political or economic instability.
