I haven't found any betting strategy for dice that makes a profit. I've tried variations of martingale and I always lose in the end. The bottom line is that you can't really change the odds with any betting strategy. You just have to quit while you are ahead.
There's no strategy in dice game, the only thing I know is the bankroll management and just bet every time with small amount. And if ever you got some winnings already learn to be calm and don't yourself too excited to dice continuously like there's no tomorrow. That's why most of the dicers doesn't get good profits from it.
