In this modern world 'Ban' is a valueless word.
That's the greatness of digital currencies like Bitcoin, unlike other types of fiat currencies.
If, the country enforces laws prohibiting the use of fiat currency for transactions, you really can't do it, but unlike digital money, news of prohibition, mouth prohibits, you can still make transactions with crypto, no matter what the country does about the prohibition law but still transactions are smooth.
Great isn't it, digital/crypto money.
