The Chinese exchange is not easy to hack. If so, it is deliberate......
I say that there is always a possibility for anything to happen in this market. Just last month Bitcoin has gone down to around 6k dollars only to rise up after a week to 10k dollars, so if you foresee with whatever information you have that Bitcoin could really go down to 4k dollars, then that might just happen. However, for me, I think that's already too low of a value, Bitcoin has already risen high enough to keep some sort of a maintaining amount, 6k more or less would be that amount, because even in at its lowest point, it didn't go down from there.
