I have no money at stake, but if I had I would be extremely wary of letting any bitcoiners or bitcoin companies play a key role in the investigation -- especially if they seem eager to help, like Sunlot, OKCoin, Kraken, and that new firm above.
We do not know what happened, except that the criminal was obviously familiar with bitcoin. So, every bitcoiner should be considered a suspect, including all the significant ex-clients. Everyone who was somehow close to MtGOX (like Roger Ver, who was a neighbor and close friend of Mark) should be suspect also.
Perhaps the Judge and/or Kobayashi and/or his hired consutants are corrupt too, but at least they should be bound -- by the obligation of their offices, and for the sake of their reputations -- to be fair, to follow the law, and to be minimally transparent in their actions. The former MtGOX management and staff, ex-clients, and other outsiders do not have any such obligations.
Jorge, it's not sane nor logical to judge every bitcoiner as a ''suspect'' and thus rule them all out from the process. It's the very same to rule every financial investigator out because they're involved with money and they're suspects!
The fact is that there's an ongoing investigation that will need every resource available to get the best results. If no bitcoin-related was ever involved, things would be in the dark for a much longer period. Take for instance someone who has no idea how bitcoin works, or how the infrastructure is implemented. How on earth could he be in the position to judge what (technically) happened?
I don't think that we must see ghosts wherever we look at. Time will eventually reveal what happened, plus, I expect it to happen earlier than April. Bitcoin is far to big to keep it steady for almost a year and up until now we've had a rather good excuse... but it slowly faints.
