I don't really know about the current state of acceptance of Bitcoins in your country in Bangladesh, but I have read some articles and mentioned that Bangladesh has not accepted Bitcoins for some reason and still considers owning Bitcoins to be an illegal activity.
Maybe you really can't do anything related to government regulations in your country. But in my opinion, don't ever think that in your country Bitcoin will never be accepted and legalized. Bitcoin and cryptocurrency are progress or an innovation that cannot be avoided.
I think that in the end a country must want and must have a way to regulate and regulate all cryptocurrencies because as time goes on more and more people in your country are interested in and even own and use crypto. So the government like it or not must have a way to be able to control the activities of its citizens.
