Well I'm sorry to tell this.. but I think Bangladesh have no idea in bitcoin industry..maybe there is ? But they can't even learned about it or could research for the benefits of bitcoin to their citizens..
They can't even imagine that this is one way to raised up their economy for their country..
We all know that Bangladesh is not a powerful and progressive country right? Why they shouldn't allowed bitcoin?.
It is a crazy decision to their executive department.. sorry to say that.
