I am from Venezuela here all the foreign currency is free trade prohibited, there are two exchange rates one that is administered by the government where only your clique benefits, the other that is super high that they call Black Dolar but the latter is for which is handled all operation clandestinely but is where the value is fixed.
The market here is like that for every $ 1 of form to receive, you receive 700.00 Bs (Local Currency) In the Black market for every $ 1 you receive 84,000.00 bs at this moment. (Local Currency)
It smells like a scam but the legal currency the state does not sell it. Well with the above, there will always be a parallel market that offers to mobilize your currency for a certain commission, the only thing is to see how viable it is.
Venezuela in this moment SUX
