EMA148 give me the idea of bottom price in weekly chart

I think EMA148 is more important than EMA200, because: e^3=20, e^4=55, e^5=148.

EMA148 is the middle axis(4950) of before-dropping price(6400) and after-dropping first bottom(3500) in 2018.11,
so i think the history will repeat:
EMA148 is the middle axis(6350) of before-dropping price(7250) and after-dropping first bottom(5450) in 2020
