Op I don't know how you understand the see the bitcoin movement as for me, it is the uses this people that affect the price of bitcoin. The more people use it the more it increases and that is where demand and supply comes to play in the usage of bitcoin. The demand makes the supply scarce and the scarce make it costly. So the price at a particular time determine by the number of usage (demand)  which would make the supply high.
SoPeople buy when the op price at a particular time determine byis low and sell when the numberprice is high so when the price is high the level of usage (demand)  which would makeselling is low and when the supplyprice is high the selling level is high.
