What affect the currency exchange rate? What currency has the highest value?

That's true, the value of fiat currencies is determined by supply and demand, and if you're planning to get profit from fiat currencies, you should think about asset allocation. You can learn more about dollar cost averaging, and I'm sure that it can help you understand how this market works and how to make the most money from investing.

It really depends on the supply and demand, and I can tell you that if you're thinking about trading fiat currencies, it's better to choose pairs like the euro and US dollar instead of the dinar of Kuwait which has the highest exchange value.

As a matter of fact, Floating currencies rates are determined by the market forces of supply and demand. How much demand there is in relation to supply of a currency will determine that currency's value in relation to another currency.

Meanwile,There are countless geopolitical and economical factors that affect the exchange rates between two countries, but a few of the most common include interest rate changes, unemployment rates, inflation rates, gross domestic product (GDP), manufacturing data, and essential commodities, in addition to the country's Balance of Payment situation (especially the Balance of Commerce part).

Furthermore, Kuwaity Dinar (KWD), is considered the highest exchange value against other currencies.
