it is difficult to say whether all countries officially recognize bitcoin, this requires massive and maximum cooperation between all countries in order to agree on this. but there are countries where bitcoin is officially recognized as currency. these are the countries that believe that the cryptocurrency will change the world for the better, in particular, it will affect the financial system and the economy as a whole. those who do not want to recognize Bitcoin are simply afraid of a coup in the country and for being used in "shadow operations", as well as for not being able to control the issuance of cryptocurrency.
Legalizing bitcoin in all countries is really an impossible ambition considering that until now there are still countries banning bitcoin and their governmento warned their people not to use and this is due to bad image of bitcoin, they dont want their people to be scammed.
