Education is really the key for them to be able to accept what is the benefits of making cryptocurrency run world wide. Some of the government has a bad views on the crypto because they are lack of knowledge of what it can do and how can it change the economy of the world. In this generation, we really need to adopt on whats on trend like crypto.
To be able accepted bitcoin as legal currency payment maybe have giving educational about how to use bitcoin and what the feature of bitcoin become legal currency payment than using fiat currency, many people still not understand and government always allowed with new digital currency payment if look benefit than using Fiat currency like USD right now.
Cryptocurrency or the world of crypto is a difficult thing not all can fully understand it in a short period, in short, it requires to learn it as it is, so that's right for the people to fully understand crypto world they need to fully understand it, in fact, I've read an article which a university offers a courses to the student about the crypto currency they will teach about what is crypto and how to earn to it. So maybe if a country's government takes a one step forward to this regards, then maybe they can be able to accept and adopt the usage if cryptocurrency; they will see how beneficial and useful using crypto to the lives of people. It will be a long journey for us to reach this world that run by cryptocurrency, but maybe there is a possibility that one day it will cam true, and that will be good for those who are already using crypto.
