well i wouldn't call it "normal"! there is a threshold for everything including corrections and downtrends and after a point it becomes abnormal to go beyond that threshold. and right now we are way past that point so we are already not-normal anymore, any lower would be even less normal.

but generally it is correct that bitcoin always had this kind of roller coaster ride with big ups and downs in long steps and will have it for a long time in the future too.
