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.
Actually, if we are being honest to look at the entire year so far none of it has looked like any year before, so I don't think we can even talk about monthly patterns now, just something else different.
75k ATH is not going to look good overall however, so most people might say this is the end if that's so. All the more better for us to get in;)
