Why do people act and behave? It is people reaction to something .... or event DUE to FEAR
Fear as the driving FORCE and MOTIVATION pushes people to the edge to act and behave either rationally or irrationally.
When FEAR of MISSING OUT of the action controls the mind of the people or crowd this develops into a strong force.
When Fear of prices going higher exceeds the Fear of going lower, the force and direction tilts in the favor and direction UP
When Fear of prices going lower exceeds the FEAR of going higher, the directional force tilts in the DOWN direction.
When the motivations is not decisive who is in the driver seat, the trend will remain horizontal range.
Is GREED the bigger motivation than FEAR, I do not think so. I believe FEAR is the mother of all motivation.
