Yes they can. Let's take the US being far richer than the El Salvador but yet El Salvadorian government has accepted bitcoin for its legal tender for payments and services but yet US being a strong hold of bitcoin are still agitating and considering the adoption of bitcoin for legal tenders.
El Salvador was able to diminish the potential conflicts between bitcoin and her economy drifts after spotting that bitcoin would boosten their regional economy following after they have structured how bitcoin would strengthen their economy infrastructures.
This is not just about waking up and adopts bitcoin for legal tenders without sentiments views and how to resolve them.
