Hello Steemit,
I have only been stacking since early 2015 but I noticed that prices always get smacked in the first week of October, which is in conjunction with China's Golden Week where they celebrate the birth of the communist party.
Below are charts which shows the smack down from last year.
Zero Hedge have more on this :

Will it happen again? Who knows, we shall see.
Thank You And Peace Be Upon You.
