anything is possible of course. but in my opinion limit of downtrend is around 6k usd. even if it drops below it, it can not stay there for so long. because mining costs are pretty high. electricity is expensive and hardware costs for bitcoin minings is also really very expensive.
The $6k support are so weak currently, I'm a little bit pessimistic the market could hold on that soon. $5k might be a real safe line , the downtrend could continue till the end of next month... Even make surprise drop back to $1k ? If there's another swing hanging for long time , hopefully it won't happen .
yes i will suppose that its price will never drop from 6k because many people think that it will more high and that is why they want to more investment in this currency and if they hold their currency for long time it will more beneficial for them ad also for bitcoin currency because holding of money is very important to increase its price.
