If you would try to place a bet like that the system would inform you that is far over the maximum amount allowed to bet cause the actual max house bankroll is only 40 BTC. Any bet which would result in higher total win would be stopped by the system.
Fair enough. I thought that you would accept a 39 BTC bet, as you wrote that it is the maximum amount you can bet. If the actual house bankroll is 40 BTC, would you accept a 39 BTC bet on a 2x multiple?
And about "Normal faucet claiming isn't provably fair - how do I know you aren't rigging it so the jackpot can't be hit?", are you really serious? First of all which jackpot are you talking about? In the roll claim (which are free money) there is a provably fair varification on the top of the screen (green button), can't you see it? And about the normal Faucet where is the reason why a Facuet should be provably fair?
Nevermind. I just noticed the provably fair box on top of the roll dice things. Apologies for the misunderstanding, and no there isn't a reason for the normal faucet to be provably fair.
How is the client seed generated? You don't allow the user to change it, so theoretically, you can generate server seeds and client seeds that won't win 0.3
BTC for over 20k rolls, and just give those to players. Less than 1% of players would end up hitting it, even if they play 1k times.
