>You're asking people to prove a negative[1]. It's a common logical fallacy.

No, I'm asking for examples of investigations where authorities have concluded that so-called 'hacks' at Bitcoin exchanges were indeed hacks and not simply thefts by scammers running the services.

>Really? This claim is trivially disprovable. Numerous people have been arrested, including Mark Karpeles of Mt Gox. You've never heard of that case? $500 million allegedly stolen

Karpeles has not been arrested over "$500 million allegedly stolen", which is perhaps why you linked to a story about something else, behind a paywall.

As for Moolah guy, if you have 'proof' that he was arrested over the hacked Mintpal coins that amounts to more than Chinese whispers on Bitcoin forums/blogs, let's see it. All your link does is link to another site that claims he was arrested, almost a year ago, and doesn't even state why.

Even if we assume he might be one day charged with the theft of the coins, that's one person involved in a Bitcoin inside job facing prosecution over it.

I'm sure I can find more than one person involved in an inside job at a bank (involving dollar amounts considerably smaller than we're talking about with Bitcoin 'hacks') doing actual time for it.
