New member here... was pointed in the direction of this thread, as a similar thing happened with someone I know (obviously on a much lesser scale).
Apologies if its already been mentioned, but one thing to point out about a degenerate gambler who is in this deep, is that they always think there will be a way out. It would be my guess that yes he may not have any money but there will be some huge pending wagers on certain markets (World Cup Winner is a perfect example and fits in with the 30-days), which could see him get out of the hole. If he wins he can claim he has borrowed the money from family etc (maybe even have a large sum to keep for himself), loses and he is in no worse a situation than before.
Again, I post this from what seems like a similar experience, and the same thing happened there. After he declared he was broke (and was bailed out) it turned out there were several large bets still pending, some of which won, and of course the winnings were gambled again until lost.
I would also be very surprised if he has told any of his family what has actually happened, and him going to the police to keep people away from them is most likely a way to try and keep them from knowing.
Good luck with eveyrone that has invested, is not nice reading about something like this!
