I don't remember when an announcement was ever made or a prompt for me to accept new terms... I assume the change happened when it was converted into the "demo" mode correct? I don't remember new terms popping up that I had to sign and agree to, of course I could be just forgetting, but I don't remember posts on here or on his website saying the investments were no longer backed.
Obviously it was very fraudolent, that's beyond doubt.
Still, the first warning was when he added a strange badly written disclaimer-like footer.
Another warning was when he changed that footer with clearer and clearly "I owe you nothing" terms.
And the final warning was the "demo mode".
