I don't think that the bitcoin prices are affected by only Chinese. I agree that China is the biggest exchange area of bitcoins but because of that we can not guess like this. Now the Bitcoin users increased lot in all countries this is also one of the reasons for the price increase and decrease. And the digital currency will not stable like traditional currency.
Chinese market used to be shaping force for the bitcoin's price in the past. But since PBoC intervention early this year this situation changed.
We have reached ATH during Chinese exchanges blockade when withdrawal of BTC/LTC were suspended. In the past this would cause major price drop, but not anymore.
The higher the adoption, the higher the market cap, the lower the fluctuation of price and stability.
