If I understand your situation correctly, you are working in Argentina, but not paying income tax because you are a non-resident, and the source of your income is outside Argentina.
In that situation, I would look into setting up an offshore corporation with a bank account to hold the income, and then get a debit card that could be used in Argentina.
This would be a hedge against the volatility of bitcoin (but maybe you see that as an advantage) and it would not require you to get cash from strangers, which I personally would be a little hesitant about, since there is a non-zero chance you are accepting dirty money and/or helping people circumvent currency controls, but I do not know the laws of Argentina, and whether or not you are violating any laws here.
