First of all , Scotland , Northern Ireland ,England , and Wales  have the same currency which in the pound sterling .However, in Great Britain, Southern Ireland uses , Euro as a currency. Then in France , before using Euro, French people used  "Le Franc". Today this currency doesn't  have any value and is not used anymore. Moreover ,  if we compare Euros to Dinar ( which is the Algerian currency ) we can say that the euro is stronger  then the dinar  now we are going to compare  Euro with the Bulgarian  currency  which  is  called " LEV"  Since the  stronger currency corresponds to the lowest number ( for example  for 1€ you can have 1,96 Lev it means that euro is stronger than the  Bulgarian currency). To conclude , we can say that the main currencies in the world can suffer from financial crises and then can fluctuate  like Dollars and Euros do.
