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 will survive no matter what happens, even if bitcoin exchanges in China will be suspended and won't be operating anymore. The question is are they the only exchange in this world? No, there are some other countries that has the potential with the growth of bitcoin. And I know that China won't let their citizens to be left behind by the bitcoin market.
