Maybe we're all wrong and the next bubble will be a yellow one again
The first bubble in 2013 December was not caused by China. It was a result of market manipulation by the Mt Gox guys. However, most of the people attributed it to China. Anyway... let us hope that the next (real) spike will be from China.
I recall it being a variety of both then again not sure how the market settled that one out since Gox was also a factor
http://www.wired.com/2013/12/china_crackdown/Bitcoin prices took a big hit on Wednesday after China’s regulators ordered the country’s payment processors to stop doing business with the country’s Bitcoin exchanges.
BTC-China, the world’s biggest Bitcoin exchange, said it would no longer take deposits in Yuan, effectively putting an end to the exchange’s pipeline of new Bitcoin buyers.
Bitcoin, the world’s most popular digital currency, which had been trading at about $700 on worldwide exchanges, dropped 35 percent to around $450 on the news. But then it did gain back some of that ground. At press time, bitcoins were trading at $575. That’s about half what a bitcoin was trading at two weeks ago.
