In the country where I come from, there is also very high inflation, but no one there considers such a logical fallacy as gambling in order to save your money from simple depreciation due to short-sighted government policies.
Everyone uses the absolutely logical method of converting their money into dollars and holding it until they need it for some purchase, so you are tied to the dollar exchange rate (which is even a bit of an investment) and get out of the situation with the local currency.
I’m wondering, if they convert their local currency to USD, how much fee are they paying? This could apply to a few people who might convert, hold it, and then change it back to their local currency when they need to buy something. As far as I know, when a country is going through hyperinflation, it’s more about surviving your daily needs, so I don’t think conversions happen that much anymore. Once you receive money from whatever source, you usually have to spend it right away.
