or is there any chance that it will not fall below 25k?
Just think of all the possibilities right now.
It's possible to fall to $25k, to $20k and even to $17k or $15k. You name it, it is bitcoin and it's nature of being volatile can drop into those prices that we're not expecting it to be low.
We've seen how $20k of 2017 became $3k on 2019.
We don't know how low it's going to be this time after hitting $69k as its last ATH. But whatever it will be, fill your bags and don't forget to buy when it's cheap.
