Lols, you realize what you're saying here?
Even if this is Russia, there is no place on this damn earth where a company can come and ask the authorities for a 50% commission to reveal data about a criminal case. If they even propose that for real they would be arrested themselves for this, and if there would be a real inquiry into this case in Russia and them refuse to release the data they claim to have they would end up in prison, in some European countries this can fall into preventing the course of justice and it comes with up to 20 years special treatment
.
Bottom line...
NOTHING was solved.
NO culprit was found!
Which again, goes against your whole tracing coins theory which has been proven unsuccessful in almost all hack cases.
I don't have much knowledge about all these laws. But there is one thing that I don't understand. If this is true, then what's wrong in making a deal with these Russian guys? Five and half years have passed since the Mt Gox scandal and the stolen funds (
BTC650,000 + tens of millions of USD in fiat cash) remains untraceable. If these guys can help recovering some of that stolen amount, then what is wrong in cutting a deal?
