See, most of the time I think that anyone who gets "hacked" either had someone do something through an inside job or they were bad with their handling of their funds, resulting in the lots funds being stolen due to incompetence. It's a shame that they saw those losses but it's not like there will be much that can be done for them now.
Bitcoin shouldn't drop because, if it was going to, it likely would have already. Only if they get dumped will such a thing happen, but at the same time there is almost no chance that will happen since they'll move it piece by piece, slowly selling them off and taking the value. More than likely, anyways. Not sure what the mentality of the hacker, or thief, is.
