We might see $2000 in 2 months... you know a lot of FUD and November fork (Core vs Miners) isn't even here yet.
If you remember the FUD from July befoer August 1, then expect something twice as big in November.
Buying now, long term, wont matter much, but if you want more bitcoins, then wait.
May be or may be not. who knows! But, I really doubt this huge fall as you guess. Bitcoin Value falls as China plans to close local exchanges. Not only this but many continuously FUD news and panic selling the main reason of this situation.
