another poorly researched and written article on your website "coinpedia" which you keep trying to get traffic for!
Bangladesh is one of 4 countries that have banned bitcoin and they did it a couple of years ago. and usage or trading of bitcoin has been illegal there. so there is nothing new about this which you made into "news".
This is one among the country where ban has been imposed long back. Nothing seems to be new with bitcoin related news from Bangladesh. Even after this there are traders in Bangladesh, but they have been operating it with assistance from banking from foreign countries.
