I agree with you that altcoins will not do much. Altcoins recently has been become pumo and dump in a way that almost they are manipulated.
I know that bitcoin will get to all time high but what I do not know is when bitcoin will get to the all-time high. Also when the beat market will begin. But I am speculating that it would be around early Q4 but it is very possible that will might begin in Q3.
The bear market likely to start after the Bitcoin ATH is created
