In my opinion banning cryptocurrency in a country is like banning the future in business. Sooner or later those goverments will surely know what is the importance of cryptocurrency. Bitcoin is the FUTURE!
I agree in your opinion, banning a bitcoin in one country it's a mistake, for me cause we know that bitcoin is give profit high profit in every investment and bitcoin is big help for them and there economy to become successful. I wish that one day there government will realize that bitcoin is give them good future.
