Asia and more so China are the epicenter of Bitcoin volume. I believe that Magi astrology has shown us many big things in advance with Bitcoin. However one must respect Chinese traditions too since they are a key market maker/mining force. The Ghost Month and festival date always occur during a moment of weakness with BTC as it is considered bad luck to be overly invested at these times. The boxes on the chart show the start of Ghost Month towards the actual Festival date. The effect post festival is much less than the lead up to it.
