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.
^ Though the BTC price is unpredictable I definitely disagree with you.
That is too much for me and I think the BTC price won't even drop below $20k. If the BTC price will break the resistance level of below $20k there will probably be a chance it will drop further but $13k is still too much for me.
However, anything could have happened but I am still hoping the BTC price will not drop like to the ground. I know one of these days BTC price will recover.
