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 .
