[ ... ] What about the Bitcoin Foundation in cooperation with Japanese authorites? what do you think???
Because i think this way will find everything within a week....
True enough, and it would be great if the press could manage to pry something out on the police investigation. When there is a lack of any reporting, this creates the appearance of a cover-up, even when there can be very good reasons to keep things quiet.
Six months though is enough time to investigate any kind of fraud or theft. How about releasing some preliminary findings, and the addresses of the supposed rogue traders who made off with the bitcoins so the coins can be traced?
MtGox has the addresses to every Bitcoin they either lost or still have in their possession. By law, these addresses are now in the hands of the administrator, Nobuaki Kobayashi. If the Japanese police are actually investigating, they should have these addresses by now. SIX DAYS is enough time to do the research. There must be some sort of negotiation happening.
Well, we still have absolutely no clue as to what happened to those coins, not even when. The only thing that seems fairly certain is that it was NOT an exploit of the malleability bug, as Mark claimed. A study by some folks at MIT concluded that at most a couple hundred BTC could have been stolen that way, possibly none.
Knowing the blockchain addresses where the coins went to is only the first, relatively easy, step. The real problem is identifying the owner of those addresses. And by now the coins must have been throroughly mixed and scattered, so even if they are spent or sold it may be impossible to detect the operation and catch the thief.
before the heist, the coins must have moved many times for legitimate purposes (e.g. cold/hot wallet flow) while in MtGOX's possession. Blockchain analysis cannot reveal when the chain of transactions stopped being MtGOX's housekeeping and became a theft. For that the police will have to examine other logs, subpoena the internet providers for access logs, interrogate Mark and other workers, etc.
It is quite possible, if not likely, that the heist was an inside job (i.e. an embezzlement rather than a theft), perhaps with accomplices among the staff workers, clients, and their friends. If that is the case, it will take a lot of work to identify the culprits, determine their actions and roles, and collect evidence against them (bank records, phone calls, emails, skype logs, etc.)
It seems that many clients of MtGOX, even if not involved in the Great Heist, were using it for things that they would rather not have the police look at. That is the declared reason of some (and, perhaps, the private reason of many others) for supporting the MtGOX revival projects by Sunlota nd others -- which make as much sense as digging up Nixon's corpse to enter him as Republican candidate for the US presidency. In particular, some clients support the revival because they hope (naively?) to use again their unverified accounts, which did not identify the owner. Thus many clients would rather hinder the investigation than help it.
Charlie Shrem and Mark Karpelès were among the Founding Members of the Bitcoin Foundation. Mark was eventually expelled, with visible reluctance, but Shrem (who may have used MtGOX for the "business" he is charged with) is still there, as well as several people which I would consider prime suspects in the case.
It is quite normal and apprpriate for the police to refuse giving out any information while an investigation is underway.
