As i know, you are not first and least gambler of the gambling history who lose 10 bitcoins. I know mostly richest gamblers have lost more than 10 bitcoins in a day.
But it is bad news about you, But i want to ask if you are continuously losing your bitcoins, than why you are continue play dice game?
I clearly tell you that you are not lucky gambler in dice game.
He said he was winning, i guess he was just to greedy and continue to gamble until he lost all.
Oh, yeah, he said he used martingale method - and if he did it manual than he did worst mistake - he was chasing losses with 10 bitcoins. If he did it with autobet then i don't think he could have stopped bets.
