Government can give the best answer of it. By the way, the major reason behind not legalized Crypto in Bangladesh is Corruption which is in their (govt officials) blood. Maybe those people can't think anything fair. Each and every sector is being corrupted by them. Until it (corruption) gets tolerable amount, we won't see anything change here. Because it increase the money laundering which will make thr county more poorer then before. So, maybe government will think about it with the other countries, but we should give up the corruption first and should be implemented a zero tolerance policy against corruption.
