The fluctuating price of Bitcoin makes it difficult for businesses to accurately price goods and services.  Imagine a store constantly adjusting prices based on the latest Bitcoin exchange rate – a logistical nightmare.  Similarly, for consumers, staying informed about Bitcoin's value to determine the best time to use it is a complex task.

The potential for misunderstandings between buyers and sellers is a valid concern.  If prices aren't clearly communicated in both Bitcoin and a stable currency like USD, confusion and frustration are likely. The lack of firsthand experiences from El Salvadorians highlights the limitations of online discussions.  Understanding how citizens are actually using Bitcoin – whether directly or through stablecoins – is crucial to evaluating the experiment's success.

The focus on ROI calculations for investors is another important point.  Bitcoin's volatility makes it challenging to predict profitability, especially for those unfamiliar with cryptocurrency markets.
