If you live in a country where the government mismanages the economy or the currency, Bitcoin is not a great choice. What most people use in that situation is just a different national currency. This is a well-known phenomenon known as dollarization or currency substitution: https://en.wikipedia.org/wiki/Currency_substitution

In most of those countries the transaction fee is a non-trivial percentage of the GDP. Using it as a currency there would be economic suicide. And the volatility would be crushing to the poor.

They'd be infinitely better off with like USDC or better yet, a USD issued CBDC.
