I see 2 scenarios happening, most likely won't happen until Oct/Nov because Sept is usually a bearish/neutral month.

If Bitcoin doesn't close below $40K on the weekly, I see if breaking the ATH and maybe going to like $75K or so in late 2021.

If it closes below $40K then, I see it either trading sideways or going to the $28K or even attempting to retest the previous 2017 ATH of $20K. Keep in mind that this might be a repeat of 2018 where everybody was expecting Nov to be a bullish month and instead it was the opposite. So its still a possibility that this will happen. Right now very little volatility and we are getting BARTS and pretty much trading with Pumps and Dumps due to low volumes.
