how do you make a strategy in a region with high inflation and high money exchange fluctuations?

I suggest that you base your strategy on the forigen currency (the US Dollar for example) and have alternative strategies to cater for the expected inflation.

This may be risky because it is more on speculation and chances but it will work, a forward hedge.
Gather all pertinent data on inflation and fluctuation plus intuition.
By then you can decide whether or not to hedge.
It is more like a gamble but will lessen the losses or give you a gain.

To make strategy to minimize profit margin squeeze. Among them: actively prevarication cash flow by using forward contracts to lock in exchange rates or avoiding the mismatch by keeping expenses and revenues for an operation in the same currency.
