1. George Soros has nothing to do with it. Inflation drives the value of currency.
2. What a great question. Truth is, no one can give you the whole answer to that question, but there are two main factors, if we decide to forget about the unexpected things that happens, such as terror and its like. Basically it is demand and supply, If the demand is higher than the supply the currency will rise, and opposite. Then what drives supply and demand? Interest rates is one thing, deficit in the trade balance, investments in a country, and other things like that. Another factor to take into consideration is the expectancy of the future development in the country.
