My personal view is he deserved to be banned by provider because he is hurting their balance he needs to be had 2 or 3 accounts on difference sites then he can do things as much he wants staying on just one is always problem.
I am also shocked about his wagering statics because I never thought about these figures here on this forum with this now community can imagine how things are going peoples are almost more than their expectations.
Just imagine he used to bet $100K in Sportsbook, I don't know how it is called a bad bet is it because the provider can't afford to pay their winnings? But for me he's taking a big risk because he's betting a big amount with one provider, maybe your suggestion of having 2-3 different casino accounts would be better, but I guess he has his reasons behind it.
BC.Game is surely having good profit from this user, and they will never want to lose him because with this surely they can have many more like this, but now they needed to be more professional with few more sites are here those are having good reputation and limits for whales.
Hopefully things will be sorted out, and he could be able to keep his fun on this site and forum as well because things like this always give good motivation to many others for having more crypto.
BC.game can't do much because it's the provider's decision, however if a whale customer like this will give his second benefit it's just that it's still a bit complicated so maybe the provider finally banned the bet.
