El Chabon, you're right, I know personally a guy who was robbed of a serious sum of money (tens of thousands of pesos) because a secretary called ahead to an accomplice at one of the places I describe.
Risk aversion is best if you don't walk around with big sums and change at different places, at different times and different amounts. Good luck in targetting you
I also know he was using that place for a good 10 years before it happened to him. It's been a bit under 6 years for me using places like that, and I've never been robbed.
Good luck to you but a patern makes you more likely to get targeted
I've been told many times, on this forum, when suggesting people go to Florida Street to change money that the same thing will happen, or you will end up getting counterfeit bills, or robbed on the way home by some random event or someone having seen you go into a known arbolito. I've been told that Florida and other places are just too dangerous to use.
If you get randomly robbed you blame it on you having dollars?
I know two guys personally who were robbed at ATM machines (and I've heard many anecdotal stories) back when the blue rate and the official rate were a few cents apart and it didn't make sense to go to all the trouble that many of us go to now to save money at private places to bring it into the country.
Another advantage, no more trips to the ATM
ATM, arbolito, private change house: this is Buenos Aires, where peril may await around the corner, and obviously doing anything related to money carries some kind of threat level.
So go for the less risky option
You mentioned withdrawing and keeping 90K somewhere - that seems to me to be a bit of an exaggeration. Personally, I don't even have 90K to my name (even in pesos), much less withdrawn and hoarded somewhere, but every month I need to spend a lot of money on rent, utilities and food and clothes for 4, school for my sister-in-law, the various activities she's involved in, entertainment, just to name a few. My household consists of 5 people (at the moment - usually it's only 4) and $500 USD a week doesn't quite fill the bill.
You have the money abroad?
Even if it did, how would I get that money here to begin with? Even that's over $2000 USD a month (my expenses are a bit larger than that). I can't pull it out of an ATM, I don't have that kind of money stockpiled here (or anywhere for that matter), I can't bring it back from the States (I haven't been back to the States in 4 years - can't afford the travel costs with everything else I have going on), I can't ask friends to bring it down all the time (I don't have enough friends coming down to keep me supplied with maple syrup, much less money) and the cost to go to Colonia and back to get dollars out of an ATM is much worse, all tickets, fees, time and what-not-else included, than using a place like I describe. Zoom is too limited in the ability to get quantities of money here, and it's only in pesos anyway. Also, how much longer are they going to be left alone?
Let's say 7000 dollar every 3 months, 2000 dollar profit, i would say it's worth a trip to Colonia
Expats who live here and have to get monthly expenses into the country really should be using a private place. The best private places are guys who work by themselves, or a couple of family members, etc.
Why exactly?
The place where my buddy got robbed after leaving was more like the first place I described in my previous post (which I used to use) - a real change house that had a "backdoor" (or in that case, literally a basement) for clients doing international transfers with them. The secretary of the agent who handed him the money took advantage of the opportunity and called ahead to her accomplice.
If he was changing that kind of money it must have been known before he came, so he will more likely be a target
The place I use now is in an apartment in a high-rise building. I go up to the 18th floor, knock on a nondescript door and am greeted by the main guy or his son personally. I've never seen anyone else in there. A desk in the main room, two bedrooms, one of which is the meeting room and the other their workroom. It's as safe as it can possibly be for what is being transacted - and this guy makes a lot more money off his transactions than he does from potentially robbing people and maybe losing his business - people who get robbed after leaving a place like this shouldn't think twice about suspecting it was him and will most likely never return (I know I wouldn't).
Easy he gets robbed and you as well, difference is he and the robbers share the profits
I also suspect that these "little" guys selling pesos on the street (Florida or wherever) work for guys like this or the big change houses. I remember one time I went to change $1000 USD in 20 dollar bills at a place on Florida and the guy I was taken to had to call someone else to get the price - they don't like a lot of small bills. But the point being it was obvious the guy I was doing business with was just a clerk. Hell, I wouldn't be surprised if the private guy I go to is only part of a bigger structure as well.
Good advice: Dont change 1000 dollar at once but divide into 3 or 4 and use different guys
There are a lot of businesses and private individuals who need to get money out of the country, and that is a supply of dollars (or euros, yuan, what-have-you).
That dollar never makes into the blue
Best for anyone who got money abroad(or earns abroad) and can't fly or doesn't want to fly back to there home country to investigate whether you can open a account in Uruguay and just go there when you need dollars. Other option could be having multiple Credit Cards
