because he doesn't TRUST other people with ACCESS to SIGNIFICANT AMOUNTS of SITE USERS' FUNDS)[/i] :
You're right on this one.
That's a personal thing that he wants to do and can't entrust this duty to anyone with the funds. The solution to avoid the drying of the hot wallet is to give this duty to anyone he trusts when he's out and can't fulfill it when the hot wallet is about to become empty.
maybe lets accept the fact that those casino he owns are already dying?
There are still plenty of players that are active so I don't think it's dying. It's just about maintaining the hot wallet before it dries out of funds.
