Thank you all, I've been reading you but not finished yet...

Trying to understand what you're saying can't help to compare the situation with Venezuela. Right now , there is no cash, no Bs anywhere. Dollar market is ruled by Dolar Today an instagram account that determines the price and according to that other people sell/buy. When is low, a lot of people looks to buy some in order to get a good price and if it goes up, people will hold on buying but trying to sell as soon as possible.

Is this a fair comparison? Has been going down slowly in the past last week and a half.
