No one can be sure about this. Bitcoin value might fall below 40K or even 10K.
40k is possible from the ATH but 10k? I don't think so.
Because I've been here in crypto space since 2016 and to be honest i never see bitcoin collapse from the ATH and fell like a rock, i mean not literally that seems the end is near..
I can't imagine what will be the reaction of some enthusiast if however they saw bitcoin suddenly collapse from 10k and tge and current ATH is 60k.
