Great news and very impressed to see a country like El Salvador is going to do that and the initiative came from its president which is exceptional.
as far as the news I read, indeed the government has submitted a bill to legalize bitcoin as a means of payment. if approved, then el salvador will be the first country to legalize bitcoin. and I think for internal problems as you describe of course the rules are a compulsion
Just a correction, it is no El Salvador the first country to legalize bitcoin but they're the first country to declare bitcoin as a legal tender. Being used legally and being declared as a legal tender are different but overall of it, very good news.
