It is clear as stated on their FAQ, the maximum bet allowed is 1btc so they should have at least 16btc to cover 1btc bet winning. Indeed, we dont know how many btc on their wallet. Foe sure, they should prove that they can pay such amount. Otherwise, whales will never come to this site.
Yeah that is true, but until now they dont even have said anything about their bankroll on how much they can pay. But not all site willing to prove this that they have big amount or low amount because it is too risky. But this is needed to make sure that site wont scam us or running away with our profit
