There's allot of asian countries already that are participating already to the development of cryptocurrencies. In line with this, it is not enough since not all people in a particular country knows about cryptocurrencies. If and only if we can induce market adoption and achieve almost all the trust of each people, it is the most effective reason why other country should accept crypto as well, as their currency.
Many countries have adopted cryptocurrency as a payment system in several service provider stores and other products. Does that action not violate the rules? Yes, it may or may not violate. Each country has its own regulations relating to the adoption of crypto as a payment system.
Asia is one of the regions that has the largest crypto market today and they continue to implement regulations on crypto. Not all countries are friendly to crypto, and that is also true in Asia.
