The VIP-club
page more or less describes what benefits users with VIP and super VIP status get.
It would be better if a user with VIP status told us about it, but as I understand, we have no one on the forum who has reached the 10th and 15th rank on Betfury. In principle, it isn't surprising because to get the 10th rank, you need to wager at least $1 million and $50 million to reach the 15th rank.
I believe privacy matters and it's risk if you let other people know that you are from Bitcoin forum and appear on the leaderboard. If you leak it at BetFury, you can leak it somewhere else because a careless practice can result in a careless habit that surely not good at all.
Perhaps people who have too big capital but are ready to use it for betting like $1M or $50M are pepole who care more about privacy. If I have $1M or $50M, and use it for bets, I would like to hide my true identity as most as possible. It's not necessarily by reasons related to governments but it can be reasons related to physical attacks and your safety.
Flexing it and revealing your true identity will put your life safety at higher risk of many kinds of physical attack.
