Howdy Dim,
Like everything down here, it's a little more complicated than that.
There are many points to factor:
A. Do you have an account at this bank? If not, there may be a transaction limit.
B. Is this the same branch that you opened the account with? If not, there may be commissions.
C. Are you prepared to declare the source of these funds and is that source tax exempt? If not, there may be taxes.
D. Your bank may require you deposit the dollar in a dollar account and then sell them through their app...which is at MEP not oficial.
