I think countries that still reject the use of bitcoin because the country's technology is inadequate, and the possibility of the country's financial management system has not been integrated with one another, and bitcoin is feared as a place for money laundering, most of which are corruptors in the country. but that does not apply to countries whose financial systems are very modern and technology from that country is already very advanced, surely the country accepts crypto currencies, especially bitcoin, for example Japan, America and other developed countries.
