I am neither bull nor bear, and relatively new at this.  But it seems to me, given the insane price rise lately, and the fact that very few people appear to think it could fall as far as the April ATH, that there is a decent chance it could fall that far or further.  Any number of (perceived) bad news items such as last week's China news could trigger it, and the very low volume provides further reason to think it could happen.  Ultimately, the value of btc will be determined by how widely it is actually used as money for transactions.  By that measure, it seems quite overvalued at $1000, since I doubt its use has increased tenfold in the last couple of months.  Overshooting on a correction could easily bring it back to $266, imo.  That is not a prediction, and I would not be surprised to see it at $2000 in January.  But I am not at all confident that $600 is the new floor.
