I will go to Australia from Bangladesh. I can carry either "US dollar" or "Australian dollar" there. But I do not know whether carrying "US dollar" will be profitable or not if I convert "US dollar" to "Australian dollar" there. Or just buy "Australian dollar" with "Bangladeshi TAKA"and carry there. How to calculate the profit?
List of exchange rate: USD/AUD = 1 / 1.41016; AUD/BDT = 1 / 55.2579; USD/BDT = 1 / 77.8907
I think that carrying "Australian dollar" will be profitable. But not sure.
