I can see this happening as I think people are too quick to dismiss the market activity in 2013/2014 as not happening again. If you compare the charts the pattern almost looks like a exact repeat of 2014 where the market crashed, briefly recovered to about 50% of the previous high which held for maybe two months and then it crashed down again even further. That time it took the remainder of 2014 and all of 2015 before the market started to slowly rise again in 2016, and taking nearly to 2017 to return to the 2013 highs.
 
Point of all this is it has only been two months since the ATH's and it takes much longer than a few weeks to fully correct and recover. Hopefully the process does not draw out as long as it did last time, and maybe not go as deep, but getting back to the OPs point, I can fully see BTC dipping to 3k yet, albeit briefly, before taking off. I can also see this drawing out all through the summer and fall and maybe not starting a earnest recovery until sometime in 2019.
