There is something that you might forgetting, the value of any currency depends on the value people agree, if we make the rock value above gold, mining activity will change to rock, gold value goes down to 0.
So the bitcoin value doesn't depend only from China, depends of all who use it, we will give the bitcoin value and the Chinese government or any other country can't control that. Doesn't matter if value goes down, it will go back to top, the big secret companies and governments wants us to forget is: we have the power, we can agree to give or not value. Believe in bitcoin, it's our key to financial freedom, and using the words of Rick (the walking dead) not today, not tomorrow, i'll bring you back the value you deserve... hey i'm not going to kill the bitcoin :-)
