Here's a example what happens with me:
When I bet big suddenly on crash game on stake it every time stops and seems like the computer is thinking about results after waiting for sometimes i bust at 1x to 1.10x, I would had believed that it is random when this incident happens with me once or twice but it happened with me more than 10 times, I betted my all funds but every time on crash it waits and think to how to bust me on short time.
Bet big? What is big in your opinion? Your understanding of big might be different from what we and owners of Stake think it is.
If you really see it happening this way, why wouldn't you record your session and put it on youtube? I could be sympathetic if I saw this happen. If you were to bet in a pattern like this ($1 W, $1 W, $10 L, $1 W, $1 W, $10 L, $10 L and so on), people might start to believe you, but for now it's your word against the casino's.
I don't think that it's rigged but if I lost a million dollars I'd probably change my mind. You can go crazy after such loss.
