Too exaggerated prediction.It would even hard to tell surpassing previous ATH on next bull run.
It is exaggerated, but never say never. After 20k will be touched again, 74k is just one step away, really (you have to visualize an exponential graph).
Of course, going 10x more is way more difficult and I think that the upper limit is exaggerated... for the next market cycle, that is.
