I wouldn't take the other side of that bet, sadly. But I think that's the only explanation for why the hot wallet would continue to be empty. Knowing that, why on earth would anyone continue to play on a site run like that? Maybe some of Bitvest's clientele could answer that for me.
I don't know if any of them will come this thread, but I'll tell you what I think. 
And OP said that
But just so you know I have it in my account on bitvest , it’s not being withdrawn , it cannot be. It’s not pending. For some reason on this particular large win my pin is not working.
The transaction pin was tagged invalid . ~ I have 2FA enabled it was not hacked or changed. It simply will not recognize the pin. The password is fine , 2FA is fine , it’s that pin.
It means this investigation is going with wrong concept. OP need a response from bitvest team/admin to reset his transaction PIN and request the withdrawal.Anyway, it is always difficult to get response from bitvest admins. Hot wallet issue is a common thing in bitvest. A user lost big amount as his withdrawal was getting delayed for empty hot wallet in the last month (I need admin of Bitvest to come here and explain! ( Not paying my winning)).
‘lightlord’ should hire a support manger & financial admin to resolve this kind of situation quickly.
