When many people are aware of the benefits of Bitcoin, logically it will not experience a setback.
El Salvador is a country that has a great history regarding Bitcoin even though there are parties who are against the concept carried out by their head of government.
Regarding the adoption of crypto, I have no comment because it is still possible that it will experience a setback considering its uncertain future, but regarding the adoption of Bitcoin, I think it will increase when they realize that Bitcoin is very good as the best hedge asset.
For Bitcoin adoption, it seems that it will also be able to develop in several other countries besides El Salvador because what has been implemented by El Salvador itself has certainly become quite clear evidence for all countries that want to do something similar in the future. In addition, the concept that has been implemented by El Salvador will also continue to get better support from its own citizens when the El Salvador government is able to build all the facilities needed by its own citizens. So I agree with what you said where the decline in Bitcoin adoption seems difficult to happen if El Salvador can continue to develop with its current concept and all other countries will also be interested in experimenting with something like that in the near future.
Above I mentioned that I cannot be sure what the future of crypto in El Salvador will be, but regarding the future of Bitcoin, I am sure El Salvador will continue to maintain what they have proven to this day.
We do not see directly what is really happening there, but through internet access we can follow if the development of Bitcoin there is getting better day by day and other countries have also done what El Salvador has done, even though other countries may not dare to issue regulations like in El Salvador.
