Bitcoin going to $8k would be like only when the internet stops working or if there would be a situation like as of in the movie DON'T LOOK UP. Other than these 2 reasons there is no other situation where the price would fall to $8k, even in this market also the price would have to fall to like 30% of what it is right now and bitcoin loosing 70% of it's value being the pinnacle cryptocurrency is hard to imagine.
Everything is possible for bitcoin even if it means reaching the bottom price this bearish season. But the only thing is we can't predict what will be its bottom price this time. Although i can say that its hard to see bitcoin again falling again below $10k since it's more backed with big institutions these days but considering that its very volatile, then it has all the chances to pull its price down to $8k if this bearish season will continue to rule in the market.
