People lined up outside currency exchange points in Tehran and other Iranian cities to buy cheaper dollars offered by the government, to sell it at higher market rate and make a quick profit.If you've ever traveled outside the country, you know exchange rates can kill you, but only if the foreign currency is worth more than your home country's currency. For example, if $1 will only buy £0.70, then you're effectively "trading down," assuming costs for goods and services are relatively equal in both countries.
