MY idea is to try and develop a system which lives up to the principle idea of being your own bank (Not your keys, not your coins.). While you earn an interest.
In that case, we would be delighted to hear your idea, since it's something that doesn't yet exist on this market as far as I am aware.
With regard to FreeBitco.in, they are among the oldest casinos on this forum, and, as you can see from their
official thread, are highly regarded by this community. It is not cool to make absurd claims without even offering a shred of evidence.
