Don't forget that bitcoin has come from $2500 at the start of the month. And it only took 2 weeks for bitcoin to get to what it is at right now.

Plus, dumping bitcoins massively usually takes less time for bitcoin to climb its way up.

I'd say that it is definitely something that you've got to prepare for. It might seem completely unlikely that it's going to happen right now, but in 2013 bitcoin went from $1300 to $500 in a few days time. It might be going up one day and all of a sudden everything is just in red.

I'd say even below $2000 is possible. It just depends on whether people panic on a massive scale, and make others panic alongside them, resulting in a big ass dump.
