It's not just the BTC that's the problem, I have 2M reddcoins which are stuck but confirmed (they used the wrong fork). Actual value is not that much, just sth less than 0.2 BTC, however, if I was one of the BTC owners that lost a significant amount I'd definitely call the authorities in Norway to take action against this Bjorke guy and the coinmarket.io guys even if he's not himself the guilty one, he's withholding information about the real owners, which is in eachself a crime. And to anyone that doesn't think there is a case, because BTC is not considered a currency but a commodity, IANAL but stealing commodities is also illegal pretty much everywhere. And the involved amount actually translates to real money directly so it's a very strong case that would really stand in courts. I'm really amazed at the people who have lost more and are still waiting from a reassurance by the devs and to get their btc back. Even if it's not a scam, even if it's not done on purpose, it's *your* BTC, you have *every* right to demand it back *now*. Not doing anything just makes whomever has all those BTC now think even safer. Who knows, eventually he'll try to cash on those BTCs and maybe even be in some tropical island having fun with your money.
I'd suggest to whomever lost the most to initiate an actual complaint to the police, preferably one in the same country. No, I'm not going to do it, because I lost too little and for me the expense would be completely outweighed by the amount of RDDs lost. If for some reason RDD goes 100x in the next week (and from 0.2 BTC, I'd lose 20 BTC) then yes, I'd probably do it, but not now.
My 2 cents.
