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.
