Market cycle psychology graph is a well-known instrument. And bitcoins price corresponds rather well with it.
The peak of the price, or the euphoric stage, has landed on December 2017 when BTC topped its record day by day. Then the investors took turns with other stages, ranging from complacency to anger. Today we are at a point of a depression as bitcoin is only slightly exceeding the $6,000 mark. But, if judging by the graph a new cycle is just around the corner - and possibly a new peak.
