It's simple, crypto market reached a new ATH and many had no other choice but to take profits, this won't definitely push the market more Futher into the moon, there will be big retrace and those who joined late will be in loss or in high panic Mode
I don't think the market has reached the final ATH limit, we are still early. However, the scenarios show a big pullback by institutional investors after some countries reactivate their economic activity mode once the vaccine has been subsidized. It can create a large retracement but does not necessarily believe in Fud. The market will break out of the side at $42k before the market makers want to create a big trap. Anyway, this trend looks bad.
