Quite the contrary. You *want* these people in your casino. Because in a second, he's going to bet 12 times and lose 12 times. That's what the house edge is all about - Martingale is a losing strategy and the more martingale betters you have, the better.

Why do you think almost all the online dice houses have "auto" modes that specifically cater to Martingale betters? Because these stupid people think they can work around their statistical disadvantage using a top secret system they bought from some internet marketeer.

Look at how the balance is decreasing. It's slow and steady, like satoshis are seeping though the creeks somehow.
