It doesn t affect residents of Argentina. In fact it affects only to illegals.
This new rules is for you guys custom made.
Don't forget actual tourists who come here for 3 months or less- just to travel! (although i guess it's consider 'illegal' to change their dollars with cuevas).
Has inflation on many products as well as hostel and transport prices not jumped in the past year to match the blue? If even actual tourists have to pay at the official rate converted back into their own currency, traveling in Argentina is suddenly not a very good price-to-value ratio.
