Yes, there's no need for governments approval for making bitcoin as international currency. And right now, we are already using bitcoin and treats it as an international currency that's why we just need to make bitcoin as a method of exchange of goods and services. It is why for me, it's already an international currency for all of us.
Yeah , I agree with you. We dont need governments approval for using bitcoin. Not only bitcoin, I mean for using any cryptocurrencies we dont need governments approval. Nowadays most of the services accept bitcoin and other altcoins as payment. From that itself one can understand , bitcoin has already established itself as a international currency .
