I am sorry but BTC is speculative... there aren't many traders, who's business is to make money to not trade BTC because of MtGox... Well at least just on that single merit, more likely would be the bad news with Dwolla, Okpay...  How about the shutdown and problems many exchanges have had...  Sure some people may be waiting for better exchanges, but most probably just are passing and will come back if there is more news/hype (positive that is).

Heck I trust my money 10x more on MtGox then on ANY new exchange unless deposits were FDIC secured.  Bitfloor is just the most recent example... poof money gone... At least with MtGox you just have lag, your money is still there when its over.

I personally think the corrections/crashes and bad news lately just scared away the big fish and a lot of monies supposedly in the pipe.  Some may be holding long term, others could be looking for an exit like the one on Sunday.
