The fact El Salvador accepted Bitcoin as a legal currency does not mean that other government across the world will accept it someday.
The answer is No, because bitcoin will be accepted generally or across the countries when each country embrace Bitcoin as a legal tender, because I know quite well that theirs some countries that accept Bitcoin as a legal tender and their's so many other countries that have not accepted bitcoin as a legal tender, if El Salvador accept Bitcoin that doesn't mean that other countries will quickly accept Bitcoin as legal tender, from observation and other things I notice, bitcoin has stayed more than ten years, but yet no country has officially accepted bitcoin aa a legal tender, the thing is that, it's acceptance will be something that will be done gradually and the top five world power countries have to accept Bitcoin before other countries will queue up to accept Bitcoin as a legal tender.
