As we approach ATH what is different compared to 2017?
We're still a year ahead of the big rally.
With both of the previous halvings there was a run up past the old ATH several months after the halving that set new ATHs and then retraced before going parabolic half a year later.
Don't compare this to 2017. Compare it to 2016 or early 2013.
We still haven't even passed the old ATH. Later next year the real fun begins. Think 6 digits.
