Historically, the month of February has always been a bad one of the crypto market. Prices usually plummet whenever it gets to this time of the year. In 2018, Price crashed from 19.7k high and ranged between $4K to $10K. We saw something similar in Feb 2020.
Those years you mentioned were not significantly a post Bitcoin halving years and as such couldn't see demand surge. 2021 is different and we don't expect and dump this February. Of course, there could be corrections but certainly not dumps. And definitely, not even at this time that institutions are showing huge interest in Bitcoin. Already the price has blown past $40,000 today. We can see $60,000 before the end of February, hopefully.
