If you ignore the fact that you are running a ponzi (this is a ponzi), then the negative trust is still appropiate.
Your "game" is not fair to players: there is no way to verify that appropiate players are receiving a payout. I haven't looked real closely at how your "game" works, however I assume it determins who gets paid something similar to the early players profit while the later players get nothing. Even if you used the first blocks that confirmed transactions you could easily use your own money (via mixers) to play early on this would make it so the majority of plays would end up loosing.
There is no real way to "verify" bets. In addition to the above you need to be trusted that appropiate players get payout. Even prime dice, which is arguably the most reputable Bitcoin casino here allows players to verify their bets to prove they received appropiate payments.
You are asking players to trust you with large amounts of money while you have no reputation. Mu believe your first post was creating your game. This is very similar to a brand new user asking to be trusted with a short term loan.
You clearly are not new to the forum based on how quickly you made it to meta and how familar you are with the trust system. This means that you are either a scammer (and should not be trusted) or plan on eventually scamming and want to protect your existing accounts reputation when you eventually run away with investor money. I am sure you knew you would probably get negative trust the hour you started your game however, a reputable member could potentially provide a history of "honesty" with their game to get it removed. I somewhat thing it is the former. I somewhat doubt that badbear will confirm or deny this, however I would speculate that you can be linked to either a scammer or are using An IP masking service like tor or a vpn.
There was recently a ponzi that was "honest" with players for a while (a few weeks) and had over 700 BTC move through their address. This built up a lot of confidence with their game allowing them to quickly accumulate large amounts of Bitcoin very quickly which means if they delayed payouts even a short time then they could run away with large amounts of Bitcoin. The end game in these ponzis is to run away once enough confidence is built up.
