Why is the Argentine peso getting stronger?

If you stop to think about it ,those people you saw in the looooong lines buying dollars called it wrong and were paying 3.21 to buy each dollar,Had they waited their pesos are worth more today and would buy them more dollars.
You are still missing the point ,this is being caused by selling the dollar not buying it.
Argentina has started doing what the rest of the world has been doing for years.
Dumping the $$$$$$$$
I have no idea if this will continue or not it is just what has been happening lately
