Did anyone take back 3 btc
I didn't for sure! But I know that I saw someone in this thread that wrote that he did it.
No the only way to get some more back is trough the group action against KnC. 2 lawyers from Sweden and 1 from USA.

You realize if KNC goes bankrupt in the process you will lose your retainer ($1,500.00 ish USD) with these lawyers. You'd be better playing poker at a casino!
Have you been following the funding KNC is closing and following the company? They aren't going bankrupt very soon..
