Martingale betting sucks. I thought OP is just having beginner's luck on this form of betting and got carried away.
I suggest OP just continue using that betting method and see the result in the long-term using it.
Even a $10,000 bankroll and you will start with lowest allowed minimum to bet can be depleted quickly using a martingale.
We had been reading Martingale being not that truly winnable in gambling though some says with so much capital this can be profitable but for me? I still love checking my luck each time I play so the technique is attitude and my behavior not to become greedy and not to seek for so much luck, multiplying my funds is more than enough for me to get away and try again in the coming days or at least week because surely ? the gambling site will take all my winning after my luck leaves me lol.
