Answers provided by AI have no value, they are just some sort of average of answers given by humans on the public segment of the Internet. There is no original though, no conscious effort, no intelligence. Often times if you read carefully what AI produces, it's just nonsense, but it's got to a level where it's grammatically correct, so at first glance it looks impressive.
That's right, AI just has a huge database that is not even up to date and based on that it creates answers like this. Although everyone immediately remembers El Salvador because it is the first country in the world to declare Bitcoin as legal tender, data shows that the rate of real adaptation in that country is even lower than in some other countries that no one else actually mentions.
I don't see any specific country as the
"best" in terms of the question posed by the OP, because the whole thing about someone looking at the success and adaptation of Bitcoin in a country through how much a country supports it is not something that should be the most important in the whole approach. Asking permission or legitimacy from politics/state to use Bitcoin is a bit absurd, because not even Satoshi contacted the FED or ECB and asked their opinion - their opinion is known to everyone anyway.
