The thing Kiur Köster and Kenneth Bjørke need to realise is 'Social Currency' is now invaluable, more so than cash and cryptocurrency.
What do I mean? Well, in this age your name and social standing can be sullied permanently and globally. The effects can be catastrophic.

Unless our bitcoin (read: BITCOIN, not altcoins) is returned, I can guarantee neither of them will be able to operate a legitimate business or gain meaningful employment again.
Just like Mark Karpelès. It will be permanent and locked online forever. Their reputations destroyed forever.

The two K's never meant for their details to be exposed, but now they are. Things have changed.
They would now be better off taking out loans and paying us back whilst bitcoin is cheap, than coming up with more excuses and inviting what's coming.

tl;dr - Get busy paying me back my BTC, or good luck trying to create new identities and flipping burgers in McDonalds for the rest of your lives.
