Bitcoin will be unstoppable these are experts words. Maybe a few countries will block it. But stopping it.... no i think not.
Yes the site can be banned and in bitcoin there are a lot of sites not only one. So! Banning bitcoin is not going to happen suppose if it is going to happen than only a few countries will do this not everyone because it is impossible to do so because it is the digital currency and people will search for some other source to use bitcoin and they will use till the end of the world and it can never be banned.
