You are lying, Bangladesh never allowed to trade virtual currency. But you mentioned you got approval!!

I have also visited your social media link where I can see something like:

How a county can give approval such a confidential business to them who cant spend only few dollar where to get an approval require a large number of dollar!! So, obviously you are trying to make people fool.
