I don't think China was the cause of the 'recent' crash. Bitcoin has definitely been in a bad downtrend for weeks now. I'm sure these 'news' about China didn't help but that's not why Bitcoin has been doing bad all these weeks.
People are just looking for reasons that is why they considered China, again, as the biggest culprit for the continuing decline of the value of Bitcoin. This is getting to be unfortunate really that the market is allowing wrong perceptions and ideas to be entering the ecosystem but that is what free market for all of us. Of course, China is not really the reason for this bloodbath but what can we do if people are thinking otherwise? Rumors are always flying off the shelves and when a story or perception is sticking to the wall then it can really affect the market, the market that has already been weakened for the past many weeks. Remember that the recent big rise of Bitcoin was attributed to the statement of China's President on the blockchain (not on Bitcoin actually) and this kind of influence is really unnecessary as we should be China-free right now.
