I think it's fairly certain to see more upside in USDARS right away. If you own pesos and live in Argentina,it's wise to sell them for silver/gold/dollars periodically. Now is a good time. I reccomend splitting with a bigger weight on USD bills, due to gold and silver volatility. Right now, the trade favors dollar strength, so you'd increase your dollar holdings next. You can rebalance this portfolio periodically, or even go back to pesos, and use term deposits to earn interest while the Peso strengthtens (usually down legs last a 1-3 months).
Good luck,
Ivan.
