OP when you are playing with high amounts of money, it's not time of experiments and in this situation it's better to play on highly trusted dice website.

DuckDice.io
You have to show us what happens before deposit and not after that because on that time it's late (I mean your post with pics).

Nothing personal but to my mind you deserve red trust. You offer bonus which is just legit way of scamming. The rules you offered for claiming that bonus isn't correct way and you know it also because it sounds almost impossible to players to claim bonus and you know 99% you will profit and players will lose their deposit. If I deposit and don't want to fight for claiming bonus anymore, it's players choise to deny or continue playing for your "bonus".
Let's explain, I deposited 1 btc and got bonus. I have to wager 1btc x55 = loss (yes it is even on 98% winning chanse and you know it), 0.5btc x 110 = loss again, 0.1 x 550 = loss and etc and etc, you are winning, sounds well.

I have one suggest for you, what about to make dice and offer 100x bonus if you will be able to wager 10000000000000x. Good idea, not?

But still to my mind that happens because people won't realize when casino offers you 55x deposit wager, they strongly believe that they win and you lose because casino exist for profit, not for charity.
