Been a long time since I visited this project, the idea itself of a regulated Bitcoin still stands strong (and even got stronger), but not with this team.
I saw all the red flags so I didn't invest, but I feel for the people who did.

As I were you guys, I would take the $ refund; after the recent dip/crash it will buy you about half the ETH you had when invested. Maybe still not fair, but try winning this case with a lawyer..it will be a (costly) dead end.
The other option is waiting till it hits the exchange, but there's no way this thing will hit more then 50 cent.
