In Bangladesh, people are not allowed to use bitcoin or any other cryptocurrency. Govt has declared it illegal. The great news is our current Finance Ministry is thinking over it and we will probably be seen Bitcoin legal in the coming years.
In Dhanmondi, there's a cafe namely "The Bitcoin Cafe". Although they don't accept bitcoin or any other cryptocurrency, I see it as a great way of promotion, people will learn more about Bitcoin and cryptocurrency. I have visited this cafe 2 times and asked to pay with Bitcoin but he wasn't agreed.

Governments change and also the ideas change. I think Bitcoin will be legalized around the world in 15-20 years. Maybe it won't be the local currency of countries but it will be inevitable to be accepted by governments and it will be one of the best currencies in the world.
