Currency exchange is the conversion of one currency into another. For example, an Indian student studying in the US will have to exchange Indian Rupees for US Dollars to pay for tuition, living expenses, and other expenditures. Several variables, such as the demand and supply for different currencies, current geopolitical situations, and economic data, cause daily variations in currency exchange rates. Because of this, it's critical to monitor currency rates and ensure you're getting the best value.
