Interesting note, the number of short positions on Bitcoin has just dropped dramatically (60% at press time), this is undoubtedly going to be people who shorted Bitcoin during the run, closing their positions now that Bitcoin has dropped so sharply.
What this could potentially mean, near-term at least, is that these formerly short positioned traders could look to switch to long positions at this dip.
This most likely will not drive the next run up, but what this could mean is that the near-term low could be in, for now at least, and as the short positions begin to close they will need to buy back their positions, which could drive a near-term recovery.
I would not make any trades on this information, but it is interesting to note that a large number of short positions have just closed, leaving the door wide open for those same traders to switch to long positions.
Edit: Note that not long after June 30th (the last major dip in short positions) Bitcoin had a minor rally
