In my opinion, $13K is quite possible this week for Bitcoin. But whales are confuse for dumping more because they know Bitcoin has more value and it is undervalue around $13k. So more dumping means draining their bags so quickly. People are really hungry for Bitcoin in new inflationary era.
Bitcoin has plummeted over the past few days but it is still above the $20k mark for now. Bear market is not over yet and bad news continues to hit the market, bitcoin is likely to fall further but i don't think it will plummet to 13-15k this week with a pretty strong 20k support. IMO, bitcoin will have a slight rally and will probably sideways for a while then continue to decline.
