The value of a country's currency has nothing to do with the size of its population or the "value of the country". Like anything else, the value of a currency is based on supply and demand. You can print $10 on a piece of paper - but its purchasing value in comparison to anything else will be relative to the supply and demand of and for those pieces of paper. If the market is flooded with dollars, then the cost of everything that can be purchased with those dollars will inflate. Ever heard of inflation?

All currencies fluctuate on a daily basis. That's why there are exchange rates and markets for exchange of foreign currencies. If your local dollar is only worth half an American dollar, you will have to pay two of your dollars to buy something that otherwise costs 1 American dollar. This is how bitcoin is priced and works, as well.
