this is already a scam
many investors were deceived and OP has always insisted he don't need the Doublebot money, but now he does not want to return investors' money? Why?
this is the main issue here. Where are the bitcoins? Why it is so difficult to return the bitcoins?
Because he don't have them man, simple as that.
As i see they are still people "invest" in this...

Why they don't read first or search before send their coins here, it's trully weird.
I suppose some of them, they deserve to lost some.
Shame though...
