buying gold in BA is as safe as going to your bank or casa de cambio and removing the same amount in dollars. one coin or bar is worth around $1500 so your risk is based on the amount you want to invest.
This is something that happens very often so don't be sold on the paranoia that there is a special tactical team positioned and ready to steal your gold. At the same time, don't be a fool, just use common sense. start slow, buy bit by bit. get a safety deposit box in the bank if you want to buy large amounts and then slowly move it out of there if you want at some later date.
my advice obviously, is to buy it physically, not as an ETF. gold can both be insurance AND an investment. as we said before, no one knows what the future holds, but my guess is after June 30th the FED will (short term) let the market cool, but as the overwhelming deflationary forces that are still in existence take hold again, Ben will have to return to his earlier strategy and flood the market with more money. they may not call it QE 3, but there will be something equivalent. US Elections around the corner, unemployment high, all spells more cash dropped into the market to make Joe MainStreet feel that things are ok. More liquidity, under whatever name, is bullish for gold and should send it (in my humble opinion) up around 1600-1800 in the next 12 months.
I look at Gold in a different way. all fiat currencies (Dollar, Euro etc) are exponentially losing their purchasing power. I wouldn't keep pesos in a safe for my grandchildren because I have no faith it would be worth anything long term. Times have changed and sadly I now feel the same way about the dollar. I do however believe gold is a medium that will maintain its value for generations.
good luck
