Currency

Currency is a system of money accepted for transactions within a particular economy or region. It can take the form of physical notes and coins or digital representations in banks and financial systems. Currency allows people to buy goods and services, save and invest, and measure the value of products. Different countries have their own currencies, like the US dollar or the euro, and exchange rates determine how these currencies compare in value. Overall, currency facilitates trade and economic activity by providing a standardized medium of exchange.
