conclusion: this time it is different. you cannot compare the bull run of 2017 one-to-one with the situation today.

reason: if you look into the chart of the pre 2017 ATH you will recognize that after the burst of a mini bubble the low after was never lower that the high of the former mini bubble. but this time the low is lower than the pre high. that leads to pure panic in the market. you can called it manipulation of the market.
