The existence of bitcoin is still pros and cons, many things must be understood and studied well. Indeed bitcoin has not become an official currency and it still has a mystery because not everyone knows about bitcoin especially to get it. Not all countries accept because they see unstable prices, anonymous users and also many things that are less acceptable by government regulations.
it is true that there are some countries that still have pros and cons against bitcoin, the government in that country cannot accept the existence of bitcoin, it is difficult for bitcoin to become a legitimate currency in a country that cannot legalize it, it takes time and patience to make the government believe in the benefits of bitcoin and the future of bitcoin
