because bitcoin is pseudoanonym and it's volatile nature so in some country their goverment wouldn't accepted bitcoin, since they're worried if bitcoin will adopted and peple do money laundry or negative things like gun or drugs trading, in fact not only with bitcoin people do that even with their own currency same thing could happen
Did you even think about about what you write, even for a little moment?
1. How exactly bitcoin's volatile nature has anything to do with banning or accepting bitcoin by governments?
2. FIAT money are FAR more dangerous, untraceable, anonymous and used by criminals worldwide than bitcoin will ever be.
3. You are basically repeating lies that mass media are feeding general public too oblivious to research the subject.
