Well, with all my experience since 2013, I was knowing and prepared for 24k... but after these last days, I can surely say to yu that everything is possible... I mean everything... 18k - 5k 
Everything as in is truly possible. We can expect for the worst case scenario and the lowest that it can be. But if bitcoin stays strong at the $20k then we're now having another all time low.
And by checking that stats, it only shows that bitcoin is on the right track. It's not how much it will increase in the future but how much the support will be for this bear and for the upcoming years to come.
