You are wrong, bitcoin can drop its price up to 300$ this year. China this september of 2017 will start its release of their fiat digital currency in their country. This will possibly trigger a huge dump by Chinese people. This is just a possibility but there is a huge possibility that it will happen. But let us not give up our hope in bitcoin when we do then bitcoin will actually suffer a big loss.
A Chinese digital currency wouldn't cause a btc price crash because people in China don't buy Bitcoin to use as a digital currency. They use it to get around capital controls imposed by the state and transfer money out of the country. Since a Chinese digital currency wouldn't address either of these uses, there's no reason to expect it to have a direct impact on the price of btc.
