I don't agree with your terms and conidtions as listed
"What is the maximum bet?
There is no maximum bet - your payout is limited to the bankroll"
That is simply not true, it cannot be true, you, your site, has a maximum amount they are able to payout and still cover all of players' deposits, why not publicly list your bank roll? Is it because this is one giant ponzi scheme?
Maybe you misunderstood something, I will try to explain it.

Our bankroll is public - under the play button you'll find the current maximal profit you can earn with the next game you play. As stated in our FAQ we limit the maximal profit on each game to 1% of our bankroll.
At this moment users can win up to 0.00117562
BTC on a game, which means our bankroll currently holds approx. 0.11756200
BTC.
There indeed is no such thing as 'maximal bet', if a player would deposit 1
BTC right now and then bet 1
BTC on "high" and win, he would get his 1
BTC + 0.00117562
BTC back. (We don't reduce the money betted, only the profit.)
Cheerz!
