I dont think there is such a pattern specially when investment is involved. It will likely be on how the economy will be moving.  See how it drops when a certain online wallet is scammed or hacked. That is why only predictions are being made and it will be with your instincts that you can rely on.

I thought there are also pattern while I am predicting OIL's price. But it really dont have also. That is why bets are made also if it will go up or down.
