how do you come into concluding on this one, even without bitcoin adoption each country has their economic challenges on how its been run and many still go more in debt, but aside the previous ones before the adoption of bitcoin as a legal tender in El-Savador, I've not heard from the news that it went ahead in seeking for another loan, remember they don't solely rely on bitcoin for their economic sustainability, there are other means of steady income.
Don't know if they have capacity to take a loan again since maybe they tighten up their belts to do this because they are suffering huge lose from the bear market season, But we don't really know the real score about that since there are other conclusion that they might be successful if they continue to accumulate while bitcoin dumps badly last couple of months or days. I never heard any hype coming from El Salvador or maybe we just missed the updates about crypto adoption on their country.
