Just now... China has declared a halt to Bitcoins exchange and operations by October... The price of Bitcoins has partially drop due to the news... However, if we can equal the population of Bitcoins user in China and invite a lot of investors... I think Bitcoin will still survive.... Hope so....
Bitcoin's survival is not dependent on just one single country and it will never be. China is trying to manage and curtail the system in their country so as to limit how every transaction is done, and I don't think that is a crime. In their last policy statement, they already said every bitcoin business must be licensed before they operate and I guess exchanges are involved as well. Over time, things will get back to normal.
