Well, don't be so negative, bitcoin adoption is something that is still coming through little by little, you don't expect it to happen over night, bitcoin is not also legal in several parts of the world, as we speak, only two countries have officially legalized bitcoin and made it a legal tender, more countries will follow in the future, and you can't be so sure that bitcoin will never be legal in Bangladesh, except you guys are been ruled by a permanent government, which I highly doubt, but even if it be true, when such a government see that alot of other, even bigger countries have introduced and legalized bitcoin payment in their system, they will have no choice but to change their mind on their stance with Bitcoin.
