We have a comprehensive list of countries that accept bitcoin as a legal tender, and if have, how good is the country development today?
what do you mean comprehensive list? as of right now only El Salvador has made bitcoin as a legal tender. the other countries are just being speculated whether they are going to be the next country to make bitcoin as a legal tender. in short, there is no "comprehensive list" since there is only one country at the moment that made bitcoin as a legal tender.
