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.
Even if chance is slim but there is a possibilities that we will go down to that figures especially if the heavy support will be break one by one and selling pressure will be so heavy. But hopefully we will not come to that point and major supports will came to lift back bitcoin to its huge price level so that we will not left shock by events since for sure many people will lost their money especially those people who hold for more longer period of time because they think bitcoin will bounce back again.
